Head black except clypeus and mandibles largely brown, antenna brown except scape, pedicel and flagellomeres 5–8 orange, meso- and metasoma orange, ovipositor sheaths black ( Figs 36A, B ). Wings hyaline except for brown spot apically on the marginal and submarginal cells of fore wing ( Fig. 1 ). Head . 1.43× wider than long when viewed dorsally ( Fig. 36C ); face rugulose-reticulate, pubescence long; deep sub-antennal groove; frons without lateral medial carina above toruli, rugose, with short pubescence; vertex rugulose-reticulate with scattered shallow punctures tending to punctate laterally, with scattered short setae; gena punctate, with scattered short setae; posterior margin of head not concave in dorsal view; occipital carina absent; malar space 0.2× height eye; clypeus 2.8× as wide as high, margin sinuate, without medial process; distance from lateral ocellus to eye margin 0.77× distance between lateral ocelli; scape 1.45× length pedicel; first flagellomere 1.19× as long as scape, 0.54× as long as second flagellomere. Mesosoma. Propleuron smooth, pubescence long, ventro-lateral carina present; pronotum smooth dorsally to rugose ventrally; mesoscutum in lateral view slightly angular antero-dorsally ( Figs 36B,F ), medial and lateral lobes strigate, with scattered short setae, admedial lines present ( Fig. 36F ); notauli distinct, carinate, narrow and deep; scutellum and axillae strigate, scutellum anteriorly with a single deep depression ( Fig. 36E ); metapostnotum scrobiculate, posterior margin convex; mesopleuron rugose, with long pubescence; mesepimeron broad, carinate; metapleuron rugose, with short pubescence; propodeum rugose, almost areolate, posterior margin scrobiculate; hind coxa strigate dorsally, pubescence long laterally, ovipositor guide distal, transverse, broad with short setae in groove and along distal margin; hind trochanter imbricate, with scattered short setae; prefemur on hind leg present; hind femur imbricate, with scattered short setae; hind tibia imbricate, pubescence short, with scattered stout emergent setae; hind femur 1.4× length hind tibia; hind tibia with ventro-apical pecten of short robust spines; hind tarsomeres 1–4 with ventro-apical pecten of short robust spines, tarsomere 1, 2.4× length tarsomere 2; tarsomere 2, 1.4× length tarsomere 3; tarsomere 3, 3.3× length tarsomere 4; tarsomere 4, 0.4× length tarsomere 5; hind tarsal claw 0.4× length tarsomere 5; fore wing veins 2r-m and 3r-m largely spectral; hind wing venation complete ( Fig. 1 ), M+Cu and r-m spectral, Cu weakly pigmented, 2-M largely spectral, except for apical third nebulous and weakly pigmented, with 2 hamuli. Metasoma. Ovate, 1.09× length of mesosoma ( Fig. 36B ); T1 and T2 broad, glabrous; ovipositor 5.2 mm . MALE. Unknown. Etymology. This species is named after the collector, Arturs Neboiss, Museum of Victoria . Distribution. This species is known only from the type locality, Licola, about 150 km east-northeast of Melbourne, Victoria ( Fig. 63 ). FIGURE 36. Aulacus neboissi sp. nov. , holotype female, (A) dorsal habitus; (B) lateral habitus; (C) dorsal head; (D) lateral head; (E) dorsal mesosoma; (F) lateral pronotum and mesoscutum. Biology. Nothing is known of the biology of this species. Comments. Although A. neboissi keys out with A. hackeri , the two species differ as follows: ovipositor guide medial, frons with lateral medial carina above toruli, and head, meso- and metasoma black-brown in A. hacker , whereas in A. neboissi , ovipositor guide distal, frons lacks lateral medial carina above toruli, head black and meso- and metasoma orange.
