This species is, with O. sihanouki nov.sp., the smallest known member of the O. Alatus group; O. sihanouki, which has four red abdominal segments, is clearly distinguished from O. sp. A5 by its much more densely punctate elytra and the greater extent of the black portion of the elytra; the specimen was found in association with the two types of O. vexans nov.sp., the largest member of the group. It is distinguished from all known members of the group with only the first three visible abdominal segments red by its uniformly testaceous legs (N.B. in the key this species has beeen inserted among the species with the first three abdominal segments red, but since the abdomen is unknown, it may be more comparable to O. sihanouki).
