Diagnosis

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 declivitaldeclivital:
pertaining to the elytral declivity
interstria variously tuberculate, never granulategranulate:
pertaining to a coarse, grainy surface texture
; and red-brown color.

This species strongly resembles A. minor from which it can usually be distinguished by the larger size and the tuberclestubercle:
a small knob-like or rounded protuberance of the exoskeleton
on declivitaldeclivital:
pertaining to the elytral declivity
interstriae 2 distinctly larger than those of other interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br /> impressed and bear smaller punctures.
.

Host plants

The species is polyphagous, but may show some preference for Dipterocarpaceae in the southern part of its range, and for Fagaceae in the northern part (Browne 1961bBrowne 1961b:
