Differential diagnosis. The habitus of E. punctipennis ( Fig. 58) is very similar to that of several other members of the Costatus group; reliable determinations will be based on examination of the aedeagus. The aedeagus is somewhat similar to that of E. panamensis ( Figs. 39, 62; differing therefrom in having a wider and shorter median lobe, a narrower and shorter basal piece, and narrower and differently shaped parameres. Externally ( Figs. 34, 58) the two species differ in color ( E. punctipennis is reddish, E. panamensis is brown), and E. punctipennis has much larger elytral punctures and smaller elytral granules, which do not link the punctures.

Distribution. Currently known from northern Mexico, Arizona, Texas, and Oklahoma ( Fig. 137).
