Description.Length of each forewing: ♂9.0–10.0 mm (n = 3), ♀11.5–12.8 mm (n = 3); median cell length about 1.3x length discoidal cell. Male. Genitalia ( Figs 63–65, 88–89): Tergite IX reduced to narrow bridge midventrally, in lateral view partly delineated from tergite X, with small convexity below phallic apparatus midapicolaterally, rounded in ventral view; abdominal tergite X apically with deep V-shaped excision; gonopods each with coxopodite about 1.5–2.0x length of harpago and well-developed irregular-shaped mesal lobe subapically; phallic apparatus with two pairs of sharply pointed, straight endothecal spines subapically. Female (association tentative, Figs 96, 97). Resembling Au. victoriana: Terminal abdomen with sternite VIII divided to form 2 plates, in ventral view broad based, tapered distally to truncate apices, in lateral view, apicolateral angles slightly produced, triangular.
