Examination of the holotype photographs of A. inaequalis ( Fig. 7 ) and A. cylindricus ( Fig. 8 ) reveal that they are the same species. The primary difference pointed out by the authors of the two species is the basal segment color of the antennae. According to Thomson (1868), the three basal segments in A. inaequalis are completely ochraceous, with the fourth ochraceous (reddish brown) with a black apex. While Bates (1866) reported the first two segments in A. cylindricus are tawny (reddish brown), the third also tawny with the apex black, and the fourth segment black. Although, it is not possible to be sure about the same antennomere colors in the holotype photographs (the same or not) differences such as this typically fall within the realm of normal intraspecific variation.

Although not previously commented on, a feature clearly visible in both holotypes and the specimens examined, is the presence on the elytra of a small, variable in size, yellowish-white pubescent tuft after midlength.
