Abstract


The Neotropical genus Salyavata Amyot & Audinet-Serville, 1843 (Heteroptera: Reduviidae) is revised. Eleven species are recognized as valid, with six described as new, arranged in three species groups. The variegata-group comprises: S. variegata Amyot & Audinet-Serville, 1843; S. dominica spec. nov. from Dominica and Lesser Antilles; S. macmahanae van Doesburg & Brailovsky, 2001; S. englemani spec. nov. from Panamá, Colombia and Venezuela; and S. webbi spec. nov. from the Amazon region in Brazil. The nigrofasciata-group comprises: S. nigrofasciata Costa Lima, 1935; S. wygodzinskyi Maldonado, 1955; S. alvarengai spec. nov. from Brazil; and S. brasiliensis spec. nov. from Brazil. The cornuta-group is proposed for S. cornuta Wygodzinsky, 1943 and S. berengeri spec. nov. from French Guiana, Trinidad and Venezuela. The first known female specimen of S. nigrofasciata Costa Lima is described and figured. Eggs and nymphs are documented for some species. Further, a summary of the species, a key to the species groups and to all species, and distribution maps are provided.

Since the publication of the first “Notes on Salyavata” (van Doesburg & Brailovsky, 2001), we received for identification several interesting collections. Thanks to this material, our knowledge of the genus Salyavata and the distribution of its species have greatly increased. Several Salyavata species are in first appearance very alike S. variegata by habitus and surface pattern, the reason that most of them were named as such by several authors.

Introduction


Since the publication of the first “Notes on Salyavata” (van Doesburg & Brailovsky, 2001), we received for identification several interesting collections. Thanks to this material, our knowledge of the genus Salyavata and the distribution of its species have greatly increased. Several Salyavata species are in first appearance very alike S. variegata by habitus and surface pattern, the reason that most of them were named as such by several authors.

Costa Lima (1935) described S. nigrofasciata from Urucuia, Minas Geraes, Brazil, Wygodzinsky (1943) S. cornuta from Taperinha, Pará, Brazil, and Maldonado Capriles (1955) S. wygodzinskyi from Mt Marahuaca, Venezuela.

Van Doesburg & Brailovsky (2001) recognized and described the Middle American species S. macmahanae, placing the rest together under S. variegata as well, but noticed already (p. 388) that the Panamanian and some Colombian specimens were different from S. variegata, which we now consider to belong to a new species. In addition, the loaned specimens contain another six undescribed species and the female of Salyavata nigrofasciata Costa Lima, 1935, which is described for the first time.

Noteworthy is a collection of nymphs of S. macmahanae and S. englemani spec. nov. from a study by the late Dr Betty McMahan on termites and their Salyavata predators in Costa Rica (1980-1989) and Panamá (1984, 1985) respectively. The collection, mainly in alcohol in small vials, was sent to the senior author as a gift, who incorporated it into the RMNH collection. From this material all nymphal instars of both species could be shown and even some differences between them can be determined; egg shell clusters from S. englemani were also present.

We base our species limits on the external morphology of the head, the colour patterns of the pronotum and abdominal spines, and the structure of the parameres and median process of the pygophore in the male genitalia. More importantly, most of the species can be unambiguously identified by the particular structure of the uninflated aedeagus, a character complex documented before in Salyavatinae (e.g., Wygodzinsky, 1943, 1948; Truong et al., 2007), but not used in a comparative way for species delimitation (see fig. 4).

All measurements are in mm; tl. = total length; in the captions of the figures, b = bar, for nymphs: 4-3/i means 4 specimens of 3rd instar. The lettering of the illustrations is adopted from the Heteroptera handbook “True Bugs of the World” (Schuh & Slater, 1995).

Systematics


Salyavatinae Amyot & Audinet-Serville, 1843

Salyavatides (Groupe 5) Amyot & Audinet-Serville, 1843: 349 (new group); Stål, 1859: 191 (discussion).
Salyavatina Stål, 1872: 120 (catalog); 1874: 80.
Salyavatitae Villiers, 1948: 340 (fauna of tropical Africa).
Salyavatinae Champion, 1898: 190 (fauna C. America); Fracker & Bruner, 1924: 166 (diagnosis); Costa Lima, 1935: 24 (n. sp.); 1940: 161, 162, 211; Wygodzinsky, 1943: 1 (revision); 1944: 350 (diagnosis gen.); 1948: 564 (genitalia); 1949: 64 (catal.); 1960: 310 (distribution); Brailovsky & Peláez, 1978 (fauna Mexico): 171; Froeschner, 1981: 78 (key); 1999: 225; Maldonado, 1990: 482 (catalog); van Doesburg & Brailovsky, 2001: 385 (n. sp.); Weirauch, 2006a: 4, ff (camouflage in nymphs); 2007: 159, ff (fossula spongiosa); 2008: 231, ff (phylogeny); Truong, Zhao & Cai, 2007: 1-20 (fauna of Vietnam).

Diagnosis.— Reduviidae with body not flattened, antennae with 4 segments, inserted on anteriorly projecting prominent tubercles at front of head, ocelli present, scutellum spined, fore legs cursorial, fore tarsus 2-segmented, abdomen laterally frequently spined.

Weirauch (2008) suggested that Salyavatinae and Sphaeridopinae are a monophyletic group, based on the particular structure of the mouthparts, and on the ventrally directed ponticus basilaris of the male genitalia. In her analyses Salyavatinae are paraphyletic with respect to Sphaeridopinae because Salyavata is more closely related to Sphaeridops (Sphaeridopinae) than to other genera of Salyavatinae. If future phylogenetic analyses confirm Salyavatinae’s paraphyly, one of the solutions might be to synonymyze Sphaeridopinae under Salyavatinae. In this scenario, the mouth parts and genitalic characters supporting the monophyly of Salyavatinae + Sphaeridopinae could be considered diagnostic for Salyavatinae as a whole.

Genus Salyavata Amyot & Audinet-Serville, 1843

Type species: Salyavata variegata Amyot & Audinet-Serville, 1843; by monotypy (fig. 8).
Salyavata Amyot & Audinet-Serville, 1843: 350 (n. gen.); Stål, 1859: 191 (list); 1872: 120 (catalog); 1874: 80 (catalog); Champion, 1898: 190 (fauna C. America); Fracker & Bruner, 1924: 166 (diagnosis); Costa Lima, 1935: 24 (n. sp.); 1940: 211; Wygodzinsky, 1943: 1 (revision); 1944: 350 (diagnosis); 1948: 564 (genitalia); 1949: 64 (catalog); 1960: 310 (distribution); Brailovsky & Peláez, 1978: 173 (fauna Mexico); Maldonado, 1990: 488 (catalog); Wygodzinsky & Lodhi, 1989: 377 (antennal trichobothria); Schuh & Slater, 1996: 158 (diagnosis); Froeschner, 1999: 225 (list); van Doesburg & Brailovsky, 2001: 386 (n. sp.); Weirauch, 2006a: 4, ff (camouflage in nymphs); 2006b: 99, ff (metathoracic gland); 2007:159, ff (fossula spongiosa); 2008: 231 (phylogeny).

Diagnosis.— New World Salyavatinae; head with antennal base unarmed or with a single spine; pronotum with each humeral angle armed with 2 stout spines, disc of pronotum with a single central spine; fore tibia cylindrical; posterolateral angles of abdominal segments II-VII armed with a single, relatively long, sharp spine. The latter also present in nymphal instars 2-5.

The genus Salyavata can be easily recognized among all Salyavatinae in particular by the strongly spined abdominal segments. Other genera, such as Elaphrocranus Berg-roth, Petalocheirus Palisot de Beauvois, and Tragelaphodes Bergroth, have spined abdominal segments as well, but the humeral angles in these genera have a single spine, not 2 as in Salyavata. Furthermore, in Elaphrocranus the abdominal spines are rather short and have the antennal base bifid apically, whereas Salyavata has just a single spine at the antennal base in some species. In Tragelaphodes the abdominal spines are relatively large, but the anterior lobe of the pronotum has a pair of spines, whereas in Salyavata there are no spines. Petalocheirus species have the fore tibia expanded, whereas in Salyavata it is cylindrical.

The eleven species of Salyavata which are here recognized can be divided into three species groups by the length of the scape (= first antennal segment), the setation on the pedicel (= second antennal segment), the size and position of the ocelli relative to the eye, the presence of large spines on the head, and some aspects of the colour pattern of the pronotum and abdominal spines.

In the variegata species group the base of the antenniferous tubercle is flat, the scape is slender and much longer than the width of the head acrosss the eyes, the setae of the pedicel are reclined and shorter than width of the segment, the ocelli are small and placed on the flat cuticule, and the distance to the eye about the same as to the other ocellus. This species group includes the type species Salyavata variegata Amyot et Audinet-Serville, 1843, as well as S. dominica spec. nov., S. englemani spec. nov., S. macmahanae van Doesburg & Brailovsky, 2001, and S. webbi spec. nov.

The nigrofasciata species group has the base of the antenniferous tubercle flat, the scape thicker and much shorter than the width of the head over the eyes, the setae of the pedicel are erect and nearly as long as the segment width, and the ocelli are large and placed on a shared ocellar protuberance, situated close together with the distance to the eye about the same as to the other ocellus. In the female the setae of the ninth tergite and adjacent sclerites are much longer than in the variegata-group or the cornuta-group (see below). This species group contains S. alvarengai spec. nov., S. brasiliensis spec. nov., S. nigrofasciata Costa Lima, 1935, and S. wygodzinskyi Maldonado, 1955.

The last group, the cornuta species group, is easily recognized by the large spines at the base of the antenniferous tubercles (fig. 16A), it also has a thick scape (similar to the nigrofasciata species group) but barely longer than the width of the head over the eyes, the setae of the pedicel are reclined and shorter than width of the segment, and the ocelli are large, placed on a shared ocellar protuberance, situated far apart from each other with the distance to the eye shorter than to the other ocellus. It has a large distribution which includes the Guianas, Brazil, Venezuela, and Trinidad, and contains several forms of which the true taxonomic status at the moment is uncertain because of paucity of specimens and lack of males. This species group includes S. berengeri spec. nov. from French Guiana, and S. cornuta Wygodzinsky, 1943, from Pará, Brazil.

The classification into the three species groups is also manifest in the colour pattern of the posterior pronotal lobe (fig. 1A-L). Basically the dorsal surface of the lobe shows two transverse rows of six light coloured spots, in an anterior and a posterior row, a constellation best to see in S. brasiliensis (fig. 1I). In the variegata-group the outermost spots of both rows are united to form an arc around the base of each anterior humeral spine (fig. 1A-E). In the cornuta-group this fusion apparently took place as well, but no arc has been formed and a central longitudinal spot proceeds backwards from the base of the central spine (fig. 1F, G). In the nigrofasciata-group, the species S. nigrofasciata and S. wygodzinskyi (fig. 1J-L) apparently forms an exception, because the white spots are expanded to such an extent that the pattern of the anterior row is largely dissolved. The posterior row of spots is, however, although more or less united with each other, still clearly recognizable. In S. alvarengai the outermost two spots of both rows are united (fig. 1H).

Wygodzinsky (1944: 350) mentioned a species specific character in the forewing: the presence or absence of a cell basad to the internal [= posterior] discoidal cell, separated by a transverse vein from the discoidal cell, and the relative size of it. Our interpretation is that the ‘crossvein’ illustrated by Wygodzinsky is in fact part of the blackish surface pattern following the forewing veins, which gives the impression of a crossvein, but observing the wing microscopically in backlighting, no trace of a crossvein is visible.

Eggs.— Studied in S. englemani only, described under the respective species.

Nymphs.— First instar shining, smooth around, sparingly set with simple short trichomes; further instars with abdominal segments II-VII each with a posterolateral spine and densly set with short and long projection trichomes; nymphs of S. englemani are described in detail below.

Etymology.— According to Amyot & Audinet-Serville (1843: 350), the name comes from Sanscrit: salya (porcupine) and vata (like).

Description.— Holotype ♂ (AMNH), Panamá, C.Z., Coco Solo Hosp. (fig. 17F). This species is very alike S. variegata in habitus and colour pattern, but could easily be distinguished by the abdominal spines which are proximally black around and by the black or yellow bases of the tibiae, and by the following characteristics:

Head (fig. 5A).— Posterior part of head behind eyes dorsally and ventrally black laterally yellow (in variegata some yellow laterad of ocelli); upper side of neck with a yellow longitudinal spot; ocelli small (0.12 × 0.14), round to a little oval, on a little raised vertex; antenniferous tubercle long; scape 1.50 times as long as width of head over eyes; base of pedicel yellow (in S. macmahanae black); eye relatively small; buccula broad; maxillary plate large; mandibular plate small.

Thorax.— Prosternal antero-lateral process of pronotum short, a little pointed, black; dorsal pronotal pattern as in fig. 1C, almost the same pattern as in S. variegata; the costal loop of the light patch on the fore wings, fainted or missing; the bases of the tibiae black; middle annulus of femora as long as distal annulus (in S. variegata shorter).

Abdomen.— Lateral spines yellow annulated, wholly black at base and with black points (fig. 2D), spine on segment VII in ♀ very short, at base broad, yellow, apically black; posterior margin of tergite VII clothed with short curled, brown setae; underside brown with yellowish markings, sternites anteriorly with a transverse yellow band and three yellow patches at the sides; underside densely set with extremely short light setae giving it a semi matt apearence except the posterior brown middle part of the sternites that are bare and glossy; hind margin of sternite VIII evenly rounded.

Genitalia.— Posterior margin of pygophore less deeply sinuate than in S. variegata; row of setae on each latero-posterior margin directed dorsally along the parameres; median process of the pygophore with apex strongly acuminate; flaps of parameres in situ more shallowly rounded than in S. variegata; aedeagus with dorsal phallothecal sclerite (dps) with apex narrow and rounded; lateral ventral sclerotizations of endosoma stout, about as long as wide (lvs); ventral endosomal process (vep) with medial margins parallel to each other (fig. 4E).

Female.— Similar to the male, somewhat larger. Terminalia (fig. 18D): posterior margin of tergite 7 brown, medially yellow, straight in dorsal view; tergite 8 medially blackish, laterally yellow, narrow and strongly curved downward; tergite 9 with lateral yellow swellings rather broad (compared to S. variegata) and protruding, central sulcus black, subbasally narrowed; tergite 10 reddish yellow; gonocoxa 8 oval, short rounding more anteriorly; gonapophysis 8 yellowish; gonoplac acute, protruding; ventral projection of the gonoplac (Wygodzinsky, 1943: 18, fig. 6, gonapófise mediana; see Weirauch, 2008: 254, fig. 19) very small, with long setae.

Median process in postero-ventral view, b = 0.1. D. External view of right paramere, b = 0.1. E. Top of right paramere, internal view, enlarged, b = 0.1.

Eggs.— (fig. 21A). Eggs of S. englemani spec. nov. were collected and subsequently hatched in vitro by McMahan in Gamboa, Panamá. The eggs were laid in batches consisting of two alternate rows of suberect eggs, more or less glued together basally. The three batches examined contain 14, 9 and 11 eggs. Eggs of S. englemani resemble those of S. variegata as depicted by Wygodzinsky (1943: 20, fig. 9A): ovoid, brown to dark brown, smooth subshining chorion, apically ending into a thickened, narrowly folded-back neck, covert by a white ring; operculum white with a dark central area fits exactly in the white ring giving the size of the opening which is 0.36 mm; eggs are 1.2 mm long (from batch 1).

Having eggs of S. englemani laid in batches is remarkable, because as far as is known in Salyavatinae from the Old World, as in species of Lisarda and Petalocheirus, they lay single, loose eggs (Ambrose et al., 2007; Miller, 1953; Cobben, 1968; Haridass, 1985; Haridass et al., 1987).

Nymphs.— (figs 19C-H, 20A-B, 21B-F). First instar smooth around (figs 20A, 21B), the whole body lavishly set with glandular trichomes; further instars mat, greyish brown, densely set with very short setae intermixed with long (0.08-0.12 mm) trichomes; lateral abdominal spines short (fig. 21G), wing pads of instars 3 and 4 with apices rounded, margins closely fringed by long trichomes

Biology.— Dr E.A. McMahan (pers. comm.) studied termite species belonging to the genus Nasutitermes in Panamá (Balboa, Smithonian Tropical Research Institute) and found Salyavata specimens, mostly nymphs of N. corniger and N. ephratae, on the nests. (For the distribution of these termite species, see Araujo, 1977).

Measurements.— Holotype, ♂, total length 13.4; scape, 2.5; pedicel, 4.5; basiflagellomere, 2.0; distiflagellomere missing [1.05]. 8 ♂♂, gem. 13.5 mm; 4 ♀♀, 14.3 mm.

Distribution.— (fig. 23). Ecuador, Colombia, Venezuela, Panamá, and Costa Rica.

Of unknown locality: 1 ♀ (USNM), “Costa Rica inter: Miami, 14.viii.1963, R.T. Johnson”, perhaps intercepted in Miami and ascribed to Costa Rica?

Etymology.— The species is named after our friend Dr Dodge Engleman, Miami, U.S.A., who collected many specimens during his stay in Panamá.

Notes.— Most of the specimens from Panamá and Colombia meet the description, even genitalic characters, but about 40% of these specimens have the bases of the tibiae more or less yellow, whilst no other differences can be found. This can be interpreted as intraspecific variation: the Coco Solo series shows no variation, but the Venezuelan series are variable. It is possible that different populations exist, perhaps predating on two related Nasutitermes species. We exclude them from the type series. It concerns the following specimens:

Description.— Holotype ♂ (USNM), Dominica, Springfield. Very similar to S. variegata due to the colour pattern of the abdominal spines (fig. 2E), the yellow base of the pedicel, and the colour pattern, incl. of the pronotum (fig. 1B). Salyavata dominica also shares with S. variegata a similar structure of the parameres (fig. 6D-E) and aedeagus (fig. 4D). It differs from S. englemani by having the anterolateral prosternal process yellowish, not black. The aedeagus although very similar between S. variegata and S. dominica, bear discrete differences such as the more divergent medial ventral endosomal processes, and the narrower lateral ventral sclerotizations (fig. 4D). Females of S. dominica differ from S. variegata in the shape of the posterior margin of the seventh tergite: in S. variegata it is slightly protruding posteriorly and broadly cleft medially, whereas in S. dominica it is strongly produced posteriorly, nearly rounded, and more strongly cleft. Females of S. dominica can be distinguished from those of S. englemani by the straight seventh tergite of the latter.

Head.— Overall colour dark brown, dorsally a pale brown area next to the eyes and a small pale yellow spot next to the ocelli; laterally with a very small pale brown longitudinal stripe including neck tubercle; postcephalic tubercle protuberant; ocelli small, smaller than in S. englemani, ocellar tubercle slightly raised over vertex, not completely flat; antenniferous tubercle long; scape about 1.3 times as long as head width across the eyes; base of pedicel yellow; eyes hemispherical in dorsal view, not reaching neither the dorsal or ventral margin of the head, and about the same size as in S. englemani; buccula broad; mandibular and maxillary plates of similar height, maxillary plate protruding.

Thorax.— Prosternal antero-lateral processes of pronotum very short, blunt, apically yellowish; in dorsal pronotal pattern (fig. 1B), the light arcs around the anterior pronotal spines are large, but narrow; costal loop of the light patch on the forewing contrasting with adjacent darker areas; all dark and yellow annuli of femora of equal width, end black with a faint yellow margin; bases of tibiae with a small yellow ring.

Abdomen.— Abdominal spines (fig. 2E) black with a yellow annulus, bases black with a faint small yellowish spot located posteriorly to the insertion of each spine, adjacent to the laterotergite suture, more or less connecting with the yellow annulus; spines of segment VII with the yellow annulus continuing broadly to the base; posterior margin of tergite VII slightly protruding and rounded in dorsal view, with numerous short curled, whitish setae; underside dark brown, each sternite with a medial pair of anterior oval yellow spots, and three to four irregular smaller ones close to the lateral margin; surface of sternites shiny, covered with evenly spaced, long setae, anterior half of each sternite with very short setae; hind margin of sternite VIII medially excavated.

Genitalia.— Parameres with a strong apical notch (similar to S. variegata), median process of pygophore with lateral margins parallel, apex broadly rounded (fig. 6C) (more acute in S. variegata), in lateral view nearly straight (fig. 6B) (sinuate in S. englemani); flaps of the parameres (fig. 6D, E) broad; in repose not parallel, somewhat inclined; aedeagus with dorsal phallothecal sclerite with lateral margins nearly parallel and broad round margin; medial ventral endosomal process with medial margins divergent and apically gently convergent; lateral ventral sclerotizations narrow and long (fig. 4D).

Female.— Very similar to the male in colour and structure, but slightly larger; spine of segment VII short, yellow with dark apex. Terminalia (fig. 18C): tergite 7 dark brown, medially yellow, dorsally densely beset with small reclined setae, posterior margin strongly produced caudally, nearly hemispherical in dorsal view, notched medially; tergite 8 yellow with paired lateral small black areas, narrow and nearly straight; tergite 9 with lateral yellow swellings broad (compared to S. variegata) and not as swelled as in S. englemani or S. variegata, central sulcus black with a faint medial pale line which is basally narrow; tergite 10 pale yellow; gonocoxa 8 oval, more angulate on its posterior margin than in S. englemani; gonapophysis 8 yellow with apex dark; gonoplac acute, protruding, ventral process very small, not noticeable.

Nymph.— Fifth instar (fig. 19A, B) brownish grey, rather smooth, wing pads clean, without fringe, femora and tibiae each with two white bands; lateral abdominal spines very short.

Measurements.— Holotype, ♂, total length 12.13; scape, 2.05; pedicel, 3.8; basiflagellomere, 1.6; distiflagellomere, 0.76.

Distribution (fig. 23).— Salyavata dominica is known exclusively from Dominica, in the Lesser Antilles. Remarkably, it is the only species of Salyavata known from the Caribbean, except Trinidad.

Etymology.— This species is named after the island where it occurs, Dominica, in the Lesser Antilles. A noun in apposition.

Diagnosis.— Species characterized by the black base of the pedicel, the black apex of the femora, the black basal portion of the tibiae, the large black abdominal spines with a yellow annulus in the middle (fig. 2F), in the female very short, strongly curved and the abdominal sternites shining, without microsetation. Male with the postero-ventral lobes of the parameres prolonged (fig. 7C), median process of the pygophore with margins gently converging to the apex which is rounded (fig. 7B), aedeagus with dorsal phallothecal sclerite narrow and apex rounded; ventral endosomal process with medial margins more sclerotized anteriorly, adjacent to each other, and strongly convergent apically; lateral ventral sclerotizations small, inconspicuous (fig. 4F). Female (fig. 18G) with posterior margin of tergite 7 straight in dorsal view; gonocoxa 8 rounded on its posterior margin; ventral process of the gonoplac visible and acute. For more detailed description, see van Doesburg & Brailovsky (2001: 388).

Nymphs (fig. 22).— E.A. McMahan preserved in alcohol nymphs from Costa Rica (La Selva Biological Station) in 23 vials containing 4-1/i, 5-2/i, 3-3/i, 3-4/i, 5-5/i whose preservation condition is moderate. First instar (fig. 22A) as in S. englemani, second to fifth instar (fig. 22B-F) largely smooth, rather shining, abdominal spines very long; wing pads, especially the mesonotal of instars 3 and 4, laterally extended into a sharp spine (fig. 22B, E), all abdominal spines with trichomes (fig. 22G).

Weirauch (2006a: 4) mentioned and depicted (fig. 19I) a 5th instar nymph of Salyavata sp. from Guatemala (Tikal, Dec. 29, 1973, leg. D.H., A.C., and K.M.C. Mistner, ex termite nest T 820 [AMNH]). This specimen belongs almost surely to S. macmahanae.

Biology.— In Costa Rica S. macmahanae predates especially Nasutitermes corniger (Motschulsky) in the rain forests. All five nymphal instars are found on the carton nests of the termites where they capture workers at repair sites using “angling” behaviour (McMahan, 1982, 1983a, 1983b, 2005).

Measurements.— Total length (average) 8 ♂♂, 14.6 mm, 20 ♀♀, 15.9 mm.

Distribution.— Panamá (new record), Costa Rica, Nicaragua, Guatemala, Belize, Mexico.

Notes.— The presence of S. macmahanae in Almirante, prov. Bocas del Toro is a new record for Panamá. Because this locality is very close to the Costa Rican border, it fits very well the known distribution of the species.

About San Carlos [1 ♀ (HNHM), Costa Rica]: this name refers probably to the river at the north border, a large area, not far from the south border of Nicaragua, at the Nicaraguan lake. Paul Schild (Pablo) collected especially near Turrialba, now and then together with Burgdorf (Carlos). This H.K.K. Burgdorf collected in Costa Rica predominantly near San Mateo, sometimes with P. Schild (Horn & Kahle, 1936: 243; 1937: 325).

For the redescription and illustrations of this species we may largely refer to Wygodzinsky (1943: 7 [female], 1948: 564 [male]) and additional notes by van Doesburg & Brailovsky (2001: 386) and fig. 9. We mention here a taxonomically important character, well illustrated by Wygodzinsky (1943, fig. 1), but not mentioned by him in the description. It concerns the yellow colour of the abdominal spines (fig. 2H, I) that mesially continues far down into the black of the abdominal margin. Salyavata variegata shares this character only with S. cornuta, and is not found in the other species of the genus. So, S. variegata is characterized by the colour of the abdominal spines in combination with the unarmed antennal bases. Although this colour of the abdominal spines is very constant throughout the distribution of the species, in some specimens from French Guiana, Suriname (Albina), and Ecuador (1 ♀ (AMNH), Sucumbios) the yellow connection downwards tend to be almost interrupted subbasally by a black surrounding, a tendency beginning at the anterior spines and progressing backwards, resulting in a very similar pattern to that exhibited by S. dominica. The spines on segment VII are shorter than the foregoing and somewhat broader at base, in females even very short, broad and almost entirely yellow. Head behind the eyes and lateral of the ocelli is usually yellowish red, except in a male from Trinidad. In the male, the hind margin of sternite 8 is shallowly excavated in the middle.

Male genitalia.— Hind margin of the pygophore bisinuate, lateral parts rounded; row of setae on dorsal edge of both lateral parts of the border directed dorso-centrally over the parameres, centrally directed edges of the parameres in situ almost straight; median process of the pygophore narrowing apically with apex rounded (more acute in S. englemani); aedeagus (fig. 4H) with dorsal phallothecal sclerite broadly rounded apically; ventral endosomal process with medial margins strongly convergent apically; ventrolateral sclerotizations wider than in S. dominica.

Female.— Terminalia (fig. 18J): posterior border of tergite 7 brown, medially yellow, barely produced, broadly cleft medially, and with a fringe of small curled, posteriorly directed setae (fig. 18J); tergite 8 yellow with paired large black areas, broad and nearly straight; tergite 9 with lateral yellow swellings narrower than in S. englemani, protruding, central sulcus black; tergite 10 pale brown; gonocoxa 8 curved on its margin; gonoplac prominent, its ventral projection conspicuous, triangular. The egg of S. variegata was described and figured by Wygodzinsky (1943: 7, fig. 9).

Distribution.— The distribution of the species is mainly restricted to the Amazon basin, including the Guianas and Trinidad, but also to the Orinoco region in the savannas of Colombia and Venezuela. It occurs as well in dryer habitats such as the Cerrado in Mato Grosso in Brazil.

Notes.— Amyot et Audinet-Serville (1843: 350) did not mention the gender of the specimen they described from Cayenne, and gave for its length 0.015 which may be interpreted as 15 mm.

A suitable specimen was not found in MNHN, but in the NMHW collection a specimen is present, suspected to be the type, a female, is 15.1 mm long and bears handwritten labels: “Cayenne Coll. Signoret.” and “variegata det. Signoret”. As it is known that the Hemiptera collection of Audinet-Serville was bought by Signoret, and that this collection finally came to the Vienna Museum (Horn & Kahle, 1935: 8: “Hemipt. via V. Signoret an Naturhist. Mus., Wien”), there is no doubt that this is the specimen, described by Amyot et Audinet-Serville. The mentioned two handwritten labels are probably from the hand of Anton Handlirsch who rearranged the old Serville collection into new boxes (pers. comm. by Dr D. Pluot-Sigwalt, quoting Daniele Matile). Moreover, this specimen which originally was glued on cardboard, shows remains of glue on underside of prothorax, abdomen and legs, and obviously has been reprepared in a way as to fulfil the posture to be figured as is presented in pl. 6 fig. 6 of the mentioned work of Amyot et Audinet-Serville. We therefore regarded this female specimen (fig. 8) to be the holotype of Salyavata variegata Amyot & Audinet-Serville, 1843.

The foregoing implies that the neotype designation by Wygodzinsky (1943: 6) becomes invalid. Because of the war he was not in the opportunity to see, or even to trace the type specimen, and supposed that it did no longer exist. Judging his excellent drawing of this neotype (female, 16 mm), which we compared with the holotype from Cayenne, it is obvious that he had the right species, although the neotype locality is Rio Javarí, Benjamin Constant, Est. do Amazonas, Brazil, near the border of Peru.

The male specimen from Rio Autaz, from NHRS was inspected and its identity confirmed by means of photographs kindly submitted by Dr Bert Gustafsson, one of them presented here in fig. 17J.

Wygodzinsky (1959: 310) mentioned a specimen of Salyavata variegata (det. Wygodzinsky) from Bolivia (Buena Vista, Ichilo, Santa Cruz, 400 m, xi.1933, Steinbach [1 ♀, Steinbach]), which we have not examined.

Measurements.— Holotype male, tl, 13.3; l/w, ± 9; w/abd, 4.2; w/pron, 3.7; l/pron, 2.9-3.3; w/head, 1.6, l/ant I, 2.4, II, ± 3.6, III, 1.85, IV, 0.5. Paratype female, tl, 15.4, l/w, 11.1, w/abd, 4.6, w/pron, 4.0, l/pron, 3.3, w/head, 1.9, l/ant I, 2.5, II, 4.3.

Distribution.— Amazonas”, Brazil (Pará).

Etymology.— The species is named in honor of Mr M.D. (“Mick”) Webb, Collection Manager Entomology of the Natural History Museum, London, who provided the first author countless times with specimens on loan and otherwise turned out to be very helpful and patient too!

Notes.— The holotype is still a bit teneral and although most of the body and appendages are rather fully coloured, especially the fore wings are still pale, the cuticle is soft and a little curled. The apically whitish spines may be not yet fully streched and coloured. The British Museum obtained the female specimen from W.W. Saunders who sold the Hemiptera in 1865. The label gives only “Amaz”, presumably in Saunders’ own handwriting. Although it is clear that Amazon or Amazonia is meant, it is a very vague indication.

The Salyavata nigrofasciata species group

Diagnosis.— Antenniferous tubercle very short, basally flat without protuberances, on its lateral margin a small tuft of setae; scape stout, shorter than width of head across eyes; pedicel four to five times as long as scape, with numerous fine, erect, long setae, in the male longer and denser than in the female; eyes large, reaching dorsal and ventral margin of head in lateral view; ventral distance between eyes not more than width of labium; ocelli very large, dome-shaped, close to each other, situated on a common elevation behind the eyes; labium narrower than in the variegata-group, length of first (visible) labial segment at least three times its width in the middle; labrum, mandibular and maxillary plates smaller than in the variegata-group; lateral postcephalic tubercles vestigial; antero-lateral process of prosternum moderately developed; subbasal black annulus of forelegs ventrally interrupted; abdominal spines black around at base, black parts of lateral abdominal margins behind the spines interrupted by a small yellowish white, more or less transverse spot; abdominal spines on segment VII very short, especially in the female; setation somewhat denser, including the forewing (except the membrane) than in the other species groups.

Distribution.— Brazil, Venezuela, French Guiana.

Note.— Wygodzinsky (1943: 3) while comparing S. variegata and S. cornuta against S. nigrofasciata, suspected already at least two different groups within Salyavata.

For a more extensive description and a fine drawing (of the male) we could refer to Wygodzinsky (1943: 8). The following can be added: eyes of female smaller than in the male (fig. 14A, B) but smaller than in S. alvarengai; the pedicel is black with a narrow yellow annulus at base and near the apex; anterior apex of clypeus strongly broadened and medially lightly excavated; the pronotum (fig. 1J) is somewhat different from the other species: the central spine is much closer to the posterior border than in the other species and the lateral spines are shorter and broad at base. Abdominal spines as in fig. 2G. Male genitalia as in fig. 14C-E; aedaegus as in fig. 4Gd, Gv and in Wygodzinsky (1943, figs 19A-C).

A striking character of this species, not mentioned by Wygodzinsky, is the extremely rich setation of body and legs with fine, long, white, erect setae, especially on the posterior part of the head and anterior part of the pronotum and even sparsely on the fore wings. The latter in addition, set with numerous very short decumbent yellow setae strewn over the margins, veins and some surfaces, especially on the base and the top section of the exocorium; the membranes are bare; the fine setation is also present on the abdominal connexiva; the sternites are brown and glossy and bear only the long fine setae. Apices of femora black.

Female.— Five specimens were available from Bahia with total lengths (in mm) of: 16.1, 14.4, 15.8, 15.9, 15.9, mean 15.6. Overall appearance is the same as in the male with minor differences; the pedicel is shorter, the ratio to the scape is about 4, whereas in the male it is 4.5 to 5; the setation is much shorter and more decumbent. Eyes are somewhat smaller: ratio of width of head over eyes to synthlipsis is 2.36; in the male 2.8 measured from five specimens each; prosternum antero-laterally rounded, without an antero-lateral process; posterior margin of abdominal tergite VII straight between the very short, triangular spines. Terminalia (fig. 18I): tergites 8 and 9 densely covered with a long curled silvery setation.

Distribution (fig. 24).— Brazil: Bahia, Minas Gerais, Paraiba.

Notes.— Costa Lima (1935) did not mention the gender of the holotype but in his figure 2, the form of the last visible (seventh) abdominal tergite clearly shows that it is a male. Dr. H. Lent of the Instituto Oswaldo Cruz stated (in: Wygodzinsky 1943: 10) that the type is a male, but slightly mutilated, an observation which was confirmed by the junior author when examining the Costa Lima collection. Costa Lima mentioned the type locality being Urucuia (Minas Gerais), but there are two places in Minas Gerais with that name. A photograph of this specimen is shown in fig. 13.

This species and the following are very distinct in colour pattern from all other Salyavata species with more or less common “variegata” pattern (fig. 17H, L). Yet, based on their morphology they clearly form a monophyletic group with S. alvarengai and S. brasiliensis.

The male specimens from French Guiana and Urucu (Brazil) fit reasonably well Maldonado’s (1955) original description; head, pronotum and scutellum densely set with short, curled, white setae; frons black, base of clypeus yellow to brown, apex of clypeus black, broadened and medially excavated, labrum partly black; in the Urucu specimen the dark body parts are black; labium black; antero-lateral prominences of prosternum present as small papillae; pronotal spines (figs 1L, 17L) extremely long and sharp; legs shiny black with redish to yellow annuli; annuli of femora 1 and 2 smaller than shown in Maldonado’s figure a, apices of femora yellow; abdominal spines (fig. 2K) long, anterior to the first spine (on tergite 2), there is an extra small spine; pygophore blackish brown with yellow side markings and three ill-defind lighter patches near the posterior margin which is roundly produced at both sides of the median process (fig. 15C); this process is brown, dorso-ventrally somewhat flattened and lanceolate in contrary with Maldonado’s statement; parameres (fig. 15C, D) distinctly S-shaped, black, apically a little flattened and club shaped; aedeagus as in fig. 4I.

Notes.— According to Maldonado, this species is close to S. nigrofasciata Costa Lima but recognizable by the absence of the pronotal black fascia (fig. 1L), the well developed anterolateral processes of the prosternum, and the length of the scape which is given as less than one-fifth of the pedicel. But there are additional differences such as the pronotum and its spines: in S. nigrofasciata they are different from the other Salyavata species in that the central and the lateral spines are much more posteriorly situated, the posterior and abdominal spines are very short, and the ocellar protuberance lower. Nevertheless, S. wygodzinskyi fits well in the nigrofasciata species group by the very short scape, the typical setation of the second segment and the large ocelli on a considerable protuberance. The anterior angle of the second abdominal connexivum has a short spine whereas in all other species there is only a small hump. The female is unknown.

Notes.— We had the opportunity to study several males from French Guiana. The differences in length of these specimens are remarkable just as several other aspects seem somewhat variable. Nonetheless, we consider all the material before us to belong only to two species: S. berengeri and S. cornuta. The females of S. cornuta can be separated into three groups by the characteristics of the terminalia. Two specimens from Brazil and two from Venezuela share a broadened base of the eighth tergite, included the broadened bases of the lateral swellings, while the middle annuli of the tibiae are long. One female from Kartabo, Bartica District (Guyana) has the same kind of ninth tergite, but the middle black annuli of the tibiae are very short. The other female from Kartabo, Bartica District has these annuli of normal length, but the eighth tergite is not broadened basally, and the swellings are more or less linear, a feature that it shares with the two females from the Trinidad Island. Additional males of S. cornuta might help to sort out the differences found in the females.

It has been shown that species of Salyavata are predators of termites, especially of species of Nasutitermes (Isoptera: Termitidae), in such an extent that one may speak of an obligatory relationship. Lubin (1983: 745) mentions among “Major predators of Nasutitermes […] several reduviid bugs (Hemiptera) that specialize on Nasutitermes, (e.g., Salyavata variegata in Panama).”

Pioneering were the studies of Dr E.A. McMahan (1982, 1983a, 1983b, 2005) in which she investigated the biology and behaviour of Salyavata in Costa Rica and Panama. She discovered and observed a most striking way in which the nymphs of the bugs (S. macmahanae) with sucked-out carcasses angled new victims mostly workers, one by one through a breach of the skin of the termite nest of Nasutitermes corniger (Motschulsky) in Costa Rica. On nests of Nasutitermes ephratae (Holmgren) the nymphs were seldom found (determination of the termites by Dr Kumar Krishna). In Panamá (S. englemani) the nymphs did not show the angling behaviour (McMahan, 2005: 206).

The dull dark gray nymphs live on the termite nest and are extremely well camouflaged in depressions and crevices at the region of the nest attachment (McMahan, 1982), covering themselves with debris (Weirauch, 2006a). In the 1st instar, the body and appendages are already set with numerous glandular trichome projections (Weirauch, 2006a: 3) (fig. 20B), to pick-up fine debris particles (fig. 20A).

The lateral abdominal “spines” of the nymphs are nipple-shaped projections of the integument set with several trichomes from which many are composed of a long projection trichome and an associate seta in a special close arrangement (figs 21G, 22G), just as on the whole dorsum of the abdomen. The associate seta may have a mechanosensory function to trigger a sticky substance from the trichome.

Adult specimens are seldom collected from termite nests. Most of the specimens in the museum collections were caught in light traps, Malaise traps, or by fogging canopies. During his stay in Suriname (1959-1963) the senior author collected S. variegata on light and found only one male against about one hundred females. Nymphs and adult of S. englemani spec. nov. were found on nests of Nasutitermes guayanae (Holmgren, 1910), by R. Cambra et al. in Darien (Panama) and named by R. Constantino.
