FIGURE 24. Aulacus glorious sp. nov. , holotype female, (A) dorsal habitus; (B) lateral habitus; (C) dorsal head; (D) frontal mandibles; (E) dorsal mesoscutum; (F) lateral mesosoma. Mesosoma. Propleuron rugulose, pubescence long, ventro-lateral carina present; pronotum rugose dorsally, rugulose ventrally; mesoscutum in lateral view rounded antero-dorsally ( Fig. 24F ), medial and lateral lobes rugosereticulate, pubescence short, admedial lines present ( Fig. 24E ); notauli distinct, carinate, narrow and deep ( Fig. 24E ); scutellum and axillae rugose-reticulate, scutellum anteriorly with pair of deep depressions, separated by a median carina; metapostnotum rugose, posterior margin scrobiculate; mesopleuron rugose, with long pubescence; mesepimeron broad, carinate; metapleuron rugose, with long pubescence; propodeum coarsely rugose, posterior margin smooth; hind coxa strigate dorsally, imbricate laterally, pubescence short laterally, ovipositor guide somewhat caudad, oblique, distal margin with long setae ventrally, long setae in groove; hind trochanter imbricate, pubescence short; prefemur on hind leg present; hind femur imbricate, with scattered short setae; hind tibia imbricate, pubescence short, with scattered stout emergent setae; hind femur 0.7× 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, 2.2× length tarsomere 2; tarsomere 2, 1.4× length tarsomere 3; tarsomere 3, 2.0× length tarsomere 4; tarsomere 4, 0.9× length tarsomere 5; hind tarsal claw 0.3× length tarsomere 5; fore wing veins 2r-m and 3r-m spectral medially; hind wing venation incomplete, R+Rs, M+Cu, Cu, r-m and 2-M absent, with 3 hamuli. Metasoma. Clavate, 1.7× length of mesosoma ( Fig. 24A ); T1 and T2 narrow, glabrous, except for a few shallow punctures dorsally; ovipositor 5.0 mm. MALE. Unknown. Etymology. This species is named after the type locality, Mount Glorious, west of Brisbane, Queensland . Distribution. The holotype was collected from Mt Glorious, Queensland ( Fig. 60 ). Biology. Nothing is known of the biology of this species. Comments. Aulacus glorious is similar to the Western Australian species A. mcmillani . Both species have the mesosoma rounded in lateral view, clavate metasoma, lack a distinct spot on the apex of the fore wing, and hind wing venation incomplete. The two species differ however in the position of the ovipositor guide and colouration (see key above for details).
