This dorsal view of the anterior body shows the rough elytra (several are missing). Note the particles of debris adhering to the elytra and elsewhere, and the brownish coloration on the elytra.

The edges of the elytra on this species are smooth, as seen in this closeup photo. This individual also has a red spot on each elytrum. Ricketts et al. says all members of the species have this spot (but that A. vittata do not), while O'Clair and O'Clair say that some individuals may not have the spot.
