REMARKS

This species from the Miocene (Upper Badenian) of Hungary has well-developed frontal and outer orbital teeth as well as shallow grooves on carapace dorsal surface that are in favour of a true ethusid. It shares carapace proportions and ornamentation with the extant Ethusa mascarone, but E. octospinosa has a more protruding front (Hyžný & Dulai 2021: 165, figs 61.1-2 and 61.1-3a, b, respectively).
