Description. As described for A. orbitalis . Subvibrissal and anterior genal bristles about 0.5X length of vibrissa. Acrostichal setae in 4 rows. Abdominal tergite 4 mostly covered with microtomentum, shiny laterally, tergite 5 with microtomentum anteromedially.

Male postabdomen: Sternite 5 as described for the species group. Surstylus with medial ridge broad, strongly projecting, anteroventral corner nearly right-angled, ventral tooth broad, rounded apically ( Fig. 136). Pregonite indistinct, fully fused with postgonite. Postgonite with lobes barely separated, anterior lobe very short, quadrate, posterior lobe pointed, long. Basiphallus narrow, with long epiphallus and preepiphallus, preepiphallus mostly sclerotized, tip transparent. Distiphallus with small, round, spinose dorsal knob, distal edge toothed ( Fig. 135).

Female postabdomen: Tergites 6–7 and sternites 6–7 wider than long, moderately sclerotized, covered with microtomentum. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 shiny, as wide anteriorly as posteriorly, pinched medially, anterior and posterior margins emarginated medially, nearly meeting sternite 8 laterally. Epiproct with moderately long anterior arms, shiny, with 2 pairs of setae and a medial unpaired seta ( Fig. 137). Cerci narrow. Sclerites of sternite 8 broad, strongly pinched near basal third, distal third covered with microtomentum, apices pointed, without hooks. Hypoproct depressed antero-medially ( Fig. 138).
