Diagnosis.

Body length 4.1–5.2 mm. Covered in dark gray and black scales, with a pale-yellow scale, V-shaped, transverse band across middle of elytra. Basal patch of black scales surrounding scutellum approx. V-shaped and extending prominently onto the second elytral intervals (as opposed to the similar A. nohirai which has an elongate I-shaped patch of black scales on the first elytral interval that barely extends on the second elytral interval basally). Pronotum lacking impunctate longitudinal midline (present in A. koguma). Scutellum covered in pale scales. Elytra with erect scales only on odd intervals. Sclerolepidia distinct and protruding. Third tarsomeres distinctly emarginate. Pedon with lateral edges approx. parallel in dorsal view, but sinuating into a blunt, rounded point. Internal sac protruding from aedeagus, with roughened musculature posteriorly and a club-shaped sclerotized structure anteriorly at its apex (Fig. 6 J 1 – 2).
