3.4−4.8 mm long (mean = 4.26 mm; n = 5); 1.70−2.53 times as long as wide. This species can be distinguished by each declivital interstria variously tuberculate, never granulate; and red-brown color.

This species strongly resembles A. minor from which it can usually be distinguished by the larger size and the tubercles on declivital interstriae 2 distinctly larger than those of other interstriae.
