Differential diagnosis. The habitus of E. costaricensis ( Fig. 43) is very similar to that of other members of the Costatus group; reliable determinations will be based on examination of the aedeagus. The aedeagus is similar to that of E. microporus in that both have the parameres lobe-like apically; however, the shapes of the lobes differ in the two species ( Figs. 46, 47). The median lobe is very simple and parallel-sided in E. costaricensis , whereas in E. microporus it is widened and minutely indented in the distal one-third, at the locations of micropores. Externally, the pronotal hood carinae are shaped slightly differently in the two species ( Figs. 42, 43).

Distribution. Currently known to be distributed from Panama to Mexico ( Fig. 141).
