Abdomen as in A. bicinctus, but male hypopygium has only two pairs of claspers, the third (middle) pair being represented by minute rudiments; upper pair longer and more slender than in A. bicinctus, smooth except for tip, which is blunt and serrated; ninth tergite has two large black pointed lobes. Legs—coxae pale ochreous, dusted with grey; trochanters ochreous. Femora ochreous-brown, with blackish ring close to base, and two other rather broad blackish rings, bordered on each edge with white; tip rather broadly ochreous-brown. Tibiae brownish-ochreous, with blackish ring near base, bordered with white; tip broadly black, preceded by narrow white ring. Tarsi blackish.
