Genus Pseudorhaconotus nov.
Type species: Pseudorhaconotus enervatus gen. nov. & spec. nov.
Diagnosis.― The new genus differs from all other genera or subgenera of the tribe Rhaconotini by the lack of vein r-m of the fore wing, the elongate pronotum with a transverse carina, the absence of a dorsope on the first metasomal tergite and the lack of an apical fringe of setae of the fore wing. It keys out in the key by Belokobylskij & Tobias (1986) (with difficulty) to Ecphylus Foerster, 1862, because of the lacking vein r-m of the fore wing; differs from Ecphylus by having vein cu-a of fore wing and vein cu-a of hind wing present (absent in Ecphylus), labial palp with 4 segments (Ecphylus: 3 segments) and third metasomal tergite sculptured (Ecphylus: smooth).
Description.― Antenna medium-sized and with about 32 segments (♀); apical antennal segments dark; scapus normal, its maximum width about twice maximum width of third segment (fig. 2); vertex superficially granulate and with some indistinct rugulae (fig. 3); maxillary and labial palpi with 6 (but 2 basal segments hardly separated) and 4 segments, respectively; anterior ocellus about in same plane as posterior ocelli but at border of steeply declivous frons (fig. 3); antescutal depression absent (fig. 7); pronotum elongate and with a strong transverse carina medially and with upcurved rim anteriorly (figs 7, 10); tegula upcurved anteriorly; mesoscutum low anteriorly (fig. 7); prepectal carina complete and well developed laterally; mesosternal sulcus complete, as row of medium-sized punctures; axillae not well differentiated; propodeum elongate, with long median carina, without tubercles and no distinct and complete areola; vein r-m of fore wing absent and vein cu-a short but distinctly developed; angle between vein r of fore wing and apico-posterior margin of pterostigma acute (fig. 1); vein CU1b of fore wing short and slightly oblique (fig. 1); first subdiscal cell of fore wing narrow and long (fig. 1); fore wing banded and without apical fringe; vein SR of hind wing absent (except for an incomplete fold) and m-cu of hind wing present (fig. 1); vein CU1a of fore wing weakly indicated and at same level as vein 2-CU1 (fig. 1); angle between veins 1-SR and C+SC+R of fore wing sharp; parastigma hardly developed; vein m-cu of fore wing interstitial; vein M+CU of hind wing much shorter than vein 1-M (fig. 1); fore tibia with a row of minute pegs (fig. 9); all tibiae with apical row of pegs; fore femur with weakly developed subbasal blister; middle tibia and tarsus slender, tarsus slightly shorter than tibia and similar to fore tarsus; hind coxa with baso-ventral protuberance; hind tibia evenly setose, not mixed with long setae (fig. 5); no distinct row of pegs on hind tibia; hind femur simple ventrally (fig. 5); first tergite with a strong latero-ventral carina, without dorsope and no distinct glymma and its spiracle in front of middle (figs 7, 8); first acrosternite short and in lateral view rounded, not protruding, tergite largely open ventrally; only second tergite with a transverse postero-oval area (fig. 8); first and second metasomal tergites of ♀ movably joined; second suture of metasoma distinctly impressed medially, rather wide and distinctly crenulate (fig. 8); third tergite without transverse striate groove; fourth and fifth metasomal tergites with sharp lateral crease; medially fifth tergite of ♀ 1.3 times longer than fourth tergite (fig. 7); sixth tergite of ♀ truncate posteriorly, smooth and largely retracted; ovipositor sheath somewhat widened apically and somewhat longer than first metasomal tergite (fig. 7).
Biology.― Unknown.
Distribution.― Europe (West Mediterranean).
Etymology.― From ‘pseudo’ (= Latin for ‘false’) and the generic name Rhaconotus Ruthe, 1854, because it looks like a Rhaconotus species but is distinctly differentiated. Gender: masculine.
