Diagnosis
3.5−4.0 mm long (mean = 3.74 mm; n = 5); 2.19−2.53 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. lewisi from which it can usually be distinguished by the smaller size and tuberclestubercle:
a small knob-like or rounded protuberance of the exoskeleton
on interstriaeinterstria:
longitudinal spaces along the elytra between the striae, which is not as<br />
impressed and bear smaller punctures.
2 not 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.

Remarks
Wood and Bright (1992) considered the species as being described by Stebbing in 1909 (Stebbing, 1909: 20) and rather than in 1907 despite listing this publication under the taxonomy section for the species. This error undoubtedly occurred because Stebbing classified Phloeosinus minor as a new species in both publications. However in 1909 he states “this amplifies the description given of this insect in [1907]” at the end of the species description. This error has been unknowingly perpetuated throughout the literature published since 1992.
