Kier (1984, p. 144) reported that no specimens of either species could now be found in the Sanchez Roig collection. As both his species were based on badly worn specimens there is no way of knowing what fascioles were present, and the plastron plating is unreported. The specimens are close to Antillaster but that genus differs by having flush rather than shallowly sunken petals which expand towards the ambitus.
