Reticulation of the head strong, but weak on front. Reticulation of the pronotum distinct, that of the elytra distinct and that of the abdomen strong, undulated and very transverse.

Comparative notes

The spermatheca of the new species is similar in shape to that of A. alboguttata Bernhauer, 1915 from Tanzania, of which I have examined the type series (in FMNHC). The proximal portion of the spermatheca of the new species is, however, less developed and is in tightly coiled, whereas in A. alboguttata the proximal portion of the spermatheca is more loosely coiled. The apical umbilicus of the distal bulb of the spermatheca is cylindrical and conical at the apex, whereas it is entirely conical in A. alboguttata. The posterior half of the brown elytra of A. alboguttata is yellow, in the new species the elytra are brown with reddishbrown base.
