REMARKS

This species from the Upper Miocene (Messinian) of Livorno, Italy, is charaterised by the characters as follows:carapace longitudinally oval and posteriorly wider; dorsal surface sculptured, regions distinct, finely tuberculate in the median part of the gastric, cardiac, hepatic and branchial areas; front produced, with two pairs of triangular teeth separated by a V-shaped depression; anterolateral margins elongated and divergent; posterior margin concave and with a clearly thickened rim. Ethusa popognensis is distinguished mainly by well-developed branchial regions crossed transversely by two granulated ridges, a character shared with ‘ Dorippe ? carpathica ’ (see above) and some other fossil Ethusa .
