It differs from the sympatric species described below in its ovate shell. Compared to the other species from the Eulo Supergroup, it is most similar to E. bundoona in size but that species differs in its more depressed spire and much wider umbilicus. Unusually, weak spiral rugae are present and similar but weaker spirals are also present in E. bundoona. E. ovata also resembles E. fenshami in shape but is larger and differs in having a short bursal duct, and in this feature, it resembles E. eulo, as it does also in having a pimple-like projection on the inner side of the operculum.
