Description

Unpigmented, spermathecal pores lateral, male pores on porophores with one genital marking on each, large conical mid-ventral marking on xviii. GMs in vii, ix presetal just median to spermathecal pores. Genital marking glands mushroom-shaped with thick stalks, one or two at each spermathecal duct, one for mid-ventral GM in xviii, two at each prostatic duct.

Male-sterile, lacking iridescence on male funnels. Hearts x–xiii oesophageal; intestinal origin xvi, caeca simple in xxvii. Spermathecae with conical ampulla, diverticulum chamber long ovate, stalk muscular.

Remarks

This is probably the male-sterile A. robustus , as most particulars agree with previous data on the species. The only exception is the mid-ventral genital marking on xviii, a condition never seen in material examined by Gates (1972).
