REMARKS

Ethusa berica, a true ethusid from the Lower Oligocene of Vicentina (De Angeli & Beschin 2008; De Angeli et al. 2010) and the Upper Eocene of Parona di Verona, Italy (Beschin et al. 2019), has a fairly long carapace, a smooth dorsal surface, with well-defined grooves, and four frontal spines, the inner ones protruding and close together, only separated by a V-shaped sinus, as revealed in the figure of a more complete and more recent specimen (De Angeli et al. 2010: fig. 7). The posterior rim is marked, wide; the presence of a strip should be checked.
