Diagnosis.

Body length 4.5–7.0 mm. Covered in pale and dark brown scales, with two obliquely shaped pale brownish, black-bordered spots across middle of elytra. Second funicular antennomere longer than funicular antennomeres 3 + 4 (Fig. 2 C View Figure 2 ) (compare with A. koguma , which has the second funicular antennomere shorter than funicular antennomeres 3 + 4). Pronotum lacking impunctate longitudinal midline (present in A. koguma ). Scutellum diagnostic: large, shiny, and lacking scales (Fig. 3 B View Figure 3 ). Odd and 2 nd elytral intervals with erect scales (scales beginning at middle of elytra on 2 nd interval; from elytral base on odd intervals). Sclerolepidia indistinct, forming low, rounded, non-protruding tubercles (Fig. 4 A View Figure 4 ). Third tarsomeres emarginate (not truncate as in A. koguma ). Pedon with lateral edges approx. parallel in dorsal view but converging evenly into a wide, blunt point. Internal sac not visible inside the aedeagus, but with a non-hooked protruding structure (unmodified in posterior 1 / 2, with roughened in anterior 1 / 2) that is clearly longer than the pedon (Fig. 6 F 1 View Figure 6 – 2 View Figure 2 ).
