Most similar to E. (B.) routhensis but differs in the shell of E. (B.) routhensis being more pupiform, with that of E. (B.) chillagoensis being broader and with the inner lip of the aperture more distinctly separated from the parietal wall. Anatomically the two species are also similar, with only some minor differences.
