Diagnostic description.

Aulacus longiventris is a distinctive species and is easily distinguished from other Australian species based on the distinctive head shape in lateral view (Fig. 60A) with pronounced raised transverse carina above toruli, long postocular space 1.0 × eye length in dorsal view and ovipositor guide oblique positioned medially.

Female. Body size (13.5–16.1) mm, ovipositor length (16.5–22.5) mm, fore wing length (9.9–12.5) mm (Fig. 59); colouration head, antenna and mesosoma black, metasoma orange, with variable amounts of black on T4 to tip, coxa reddish-brown, fore and mid legs orange, tibiae and tarsi cream-coloured except tarsomere 5 black, hind legs orange, metatibia dark brown except, hind tarsi cream-coloured except most of first tarsomere and fifth segment black, ovipositor sheath dark brown with large cream-coloured apex, wings hyaline, fore wing with indistinct infuscation appically on 1st marginal and 4th submarginal cell (Fig. 60G), hind wing veins spectral; head shape quadrate, width (1.0–1.1) × length, postocular space (1.0) × eye length in dorsal view (Fig. 60C), raised transverse carina above toruli, malar space (0.1-0.2) × height of eye (Fig. 60A); length of scape (1.8) × length of pedicel, 1st flagellomere (1.3–2.2) × length of scape, (0.7–0.8) × 2nd flagellomere; mesosoma length (1.5–1.6) × height, mesoscutum in lateral view rounded antero-dorsally (Fig. 60D); mesoscutum length (0.8–1.1) × width in dorsal view (Fig. 60E); medial lobe rugose; ovipositor guide transverse, positioned anteriorly (Fig. 60 F); ovipositor sheath length (1.8–2.0) × fore wing length (Fig. 59); 2-Rs+M (0.4–0.5) × 1-Rs+M, three hamuli, equidistant (Fig. 60G); metasoma clavate,T1+T2 length (4.7–5.4) × width in dorsal view.

Males. Body size (13.0–19.9) mm, similar to females except coxa and trochanters black.
