Occurrence. Ostracod associations coming from the Upper Triassic (Tropites subbullatus/Anatropites spinosus zones of the Tuvalian substage) clays and sandstones of the Mufara Formation outcropping along the west side of Monte Gambanera (Castel di Iudica, central-eastern Sicily) have been analysed for the first time.

Massive stocky carapace with a symmetric triangular shape; quite symmetric relative to H max; general shape of valves similar, but LV is significantly larger than RV and radius of curvature of PB smaller than anterior one; LV overlaps RV all around the carapace with minimum at PVB; maximum of H located at mid L or in front of mid L; maximum of L at mid H or a little belowmid H; VB quite straight; presence of a very fine flattening at AB of RV in blade shape and a spine located near the maximum of convexity of AB; two more or less distinct spines at PVB of RV; one spine at AB of LV; dorsal view biconvex with valves almost symmetric in shape and W max at or just behind mid L; surface seems to be smooth.
