(figs 1-10)

FIG2

Figs 1-10. Pseudorhaconotus enervatus gen. nov. & spec. nov., ♀, holotype. 1, wings; 2, antenna; 3, head, dorsal aspect; 4, head, anterior aspect; 5, hind leg; 6, outer hind claw; 7, habitus, lateral aspect; 8, first-third metasomal tergites, dorsal aspect; 9, fore tibia, anterior aspect; 10, mesosoma, dorsal aspect. 1, 2, 5, 7: 1.0 × (= scale-line); 3, 4: 1.6 ×; 6: 3.0 ×; 8, 10: 1.3 ×; 9: 1.9 ×.

Material.― Holotype, ♀ (NMS), ‘Spain, Granada, Orgiva, 30S VF68, 500 m’, ‘interception trap, 25.x.2007, Jose Luis Ruiz de la Cuesta’, ‘don. A. Ribes, 11223’.

Holotype, ♀, length of body 4.5 mm, of fore wing 2.9 mm.

Head.― Antenna slender, incomplete with 22 segments remaining (but according to photograph of unprepared specimen 32), outer side of third segment flattened, superficially granulate and sparsely setose, third segment 1.1 times as long as fourth segment, length of third, and fourth segments 3.0 and 3.4 times their width, respectively; occipital carina largely present but absent ventrally near wide hypostomal carina; length of maxillary palp 0.8 times height of head; length of eye equal to temple in dorsal view (fig. 3); head in dorsal view behind eyes narrower than at level of eyes; OOL:diameter of ocellus:POL = 9:3:5; frons flat and shiny, superficially granulate and largely transversely rugose; vertex and temple superficially granulate and with a few indistinct rugulae; face granulate and with some transverse striae, but smooth medially; clypeus rather small, flattened, smooth, shiny, its ventral rim concave and strongly produced forwards; length of malar space 1.4 times basal width of mandible and 0.6 times height of eye in lateral view.

Mesosoma.― Length of mesosoma 1.8 times its height; side of pronotum costate carinate, medio-anteriorly with some transverse carinae; lateral carina of mesoscutum obsolescent; prepectal carina rather wide ventrally; mesopleuron superficially shiny, granulate and largely rugose medially and below precoxal sulcus smooth; precoxal sulcus medially weakly impressed and crenulate-rugose; pleural sulcus coarsely crenulate; episternal scrobe not differentiated; metapleuron sparsely setose, smooth anteriorly and remainder coriaceous-rugose; mesoscutal lobes shiny, largely glabrous, flattened and superficially granulate; notauli complete, shallow, rather wide and distinctly crenulate (fig. 10); scutellar sulcus distinct, but narrowed medially, with 4 lateral crenulae; scutellum flat and granulate, with some striae; medially and posteriorly propodeum superficially granulate, medio-posteriorly superficially rugose (fig. 10).

Wings.― Fore wing: pterostigma elongate (fig. 1); r issued at middle of pterostigma (fig. 1); r longer than width of pterostigma; r:3-SR+SR1:2-SR = 7:41:16; 1-CU1:2-CU1 = 1:20; basal cell (except dark part near 1-M) and subbasal cell (except posteriorly) nearly glabrous; m-cu interstitial. Hind wing: M+CU:1-M = 11:29; m-cu medium-sized and directed basally and situated basally of 1r-m.

Legs.― Fore femur 3.1 times as long as wide; fore spur 0.5 times as long as fore basitarsus; hind coxa shiny, superficially granulate; length of femur, tibia and basitarsus of hind leg 3.0, 9.3 and 5.4 times their width, respectively (fig. 5); hind femur shiny, and apical half coriaceous; hind tibial spurs 0.25 and 0.35 times as long as hind basitarsus; hind basitarsus slightly wider than second tarsal segment.

Metasoma.― First tergite 1.2 times as long as wide apically, its surface shiny and very superficially granulate, flattened but depressed postero-sublaterally, its dorsal carinae complete (fig. 8), parallel except basally and tergite flat basally; second tergite distinctly longitudinally costate-striate, but with two granulate patches medio-laterally (fig. 8); third-fifth tergites basally striate and remainder superficially granulate, but posteriorly smooth; length of setose part of ovipositor sheath 0.34 times fore wing, 0.4 times metasoma and 0.9 times length of hind tibia; ovipositor sheath somewhat widened subapically and truncate apically, but with small appendix (fig. 7).

Colour.― Dark brown; scapus, head, pronotum, remainder of mesosoma (except propodeum) dorsally partly, middle and hind coxae and first tergite chestnut brown; remainder of antenna (but darkened apically), fore coxa, trochanters and trochantelli, base of tibiae and tarsi yellowish-brown; palpi brown but darkened basally; basal third of pterostigma and 1-R1 pale yellowish; veins largely (but M+CU1, cu-a and 2-A yellowish as veins of hind wing), as remainder of pterostigma dark brown; band below base of pterostigma subhyaline, fore wing basally pale yellowish and remainder of membrane dark brown or brown.

Distribution.— Spain (Andalusia).

Etymology.— From ‘ex’ (Latin for ‘out of’) and ‘nervus’ (Latin form nerve) because of the lacking nerve of the fore wing.
