immarginatus group

This monotypic species group involves specimens whose humeral umbo is very prominent, the elytra are conspicuously depressed behind the umbo with the middiscal setal tuft set in the depression, and the posterior two­thirds of the elytral disc is strongly convex (fig. 40). A. immarginatus (Chevrolat) specimens are known only from the highlands of Colombia.
