Gondwanocentrus Quicke & Butcher gen. nov.

Figs 1–8 .

Antennae with fewer than 20 flagellomeres. Terminal flagellomere pointed but not acuminate, wider than basal flagellomeres. Basal flagellomeres elongate and narrower than distal ones. Pedicellus large, approximately half length of scapus. Head coarsely sculptured. Eyes completely glabrous. Face transversely striate, roundly bulging. Hypoclypeal depression dorsally rounded. Malar suture absent. Maxillary and labial palps with 6 and 4 segments, respectively. Frons not depressed behind antennal sockets, flat. Ocelli small. Occipital carina complete, ventrally joining hypostomal carina far from base of mandible. Pronotum formed into a short ‘neck’. Mesosoma largely coarsely sculptured. Propleuron with posterior flange. Notauli narrow, distinctly impressed at anterior. Scutoscutellar suture complete. Scutellar sulcus wide with string medial carina. Scutellum with lateral carinae. Epicnemial carina complete. Precoxal sulcus deep, oblong, coarsely foveate. Metanotum with complete midlongitudinal carina; posterior margin not protruding. Propodeum sharply angled in lateral view, with short midanterior carina that divides to form pair of curved carinae and these are met by a pair of submedial carinae making a hard-to-discern areola; sublateral carinae short, forming a weak apophysis; lateral carinae distinct. Fore wing: pterostigma large; vein r-rs issuing from distinctly beyond the middle, perpendicular; 2nd submarginal cell long, distinctly narrowing distally; vein 1RS well developed; vein (RS+M) a sinuate, particularly strongly curved distally; vein 1rs-m not tubular or pigmented; m-cu antefurcal; M+CU completely tubular and weakly sinuate; 1cu- a postfurcal; 2cu-a present. Hind wing: vein M+CU slightly longer than 1-M. Coxae coarsely sculptured. Tarsi not shortened. Hind tibia without striate sculpture medio-laterally; apico-medially with moderately developed comb of setae but these not adpressed. Claws with small rounded basal lobes and with pecten. Hind coxa coarsely sculptured. Tergites 1–3 sculptured, largely concealing more posterior tergites; with complete lateral crease. Tergite 3 curved in dorsal profile with narrow lamelliform posterior margin. Ovipositor moderately exserted, needle-like.

Type species. Gondwanocentrus humphriesi Butcher & Quicke sp. nov.
