Barclay& H. Mendel(34 BMNH).   Differential diagnosis.The habitus of this species ( Fig. 9) is very similar to that of several other members of the Costatusgroup; reliable determinations will be based on examination of the aedeagus ( Fig. 13). The median lobe is nearly parallel-sided in dorsal view and quite blunt apically; in lateral aspect it is strongly curved. The aedeagus is similar in general shape to that of  E. ecuadorensis( Fig. 21), but differs in shapes of the median lobe and parameres, and curvature of the medial lobe. Externally,  E. hintoniis slightly larger than  E. ecuadorensis(ca. 1.71 vs. 1.56 mm), but otherwise they are very similar.   Distribution.Currently known from two localities in Bolivia( Fig. 127). Oliva (1986)reported specimens from Tucuman Province, Argentina; these specimens were not seen during this revision, and therefore could not be confirmed as  E. hintoni. 1937-06-12 1937-06-13 1937-06-12 BMNH H.
