( Figs. 5 View Fig A-E)

Generic Differential Diagnosis (modified after De Deckker 1979a and George and Martens 2003): Valves rounded in lateral view, externally covered with polygonal elevation and rounded or pointed tubercles ( Figs. 5A, B, C, D View Fig ,). Ventral side of carapace ( Fig. 5E View Fig ) with anterior lip-like expansions of valve margins, near mouth; large part of ventral surface plate-like, set with 2-3 rows of rounded elevations and bordered by an elevated outer list. Each valve with prominent, rounded and opaque antero-dorsal eye-tubercles ( Figs. 5C, D View Fig ). Mandibular palp with 6 plumose internal setae and about 10 apical setae on terminal segment. Maxillula with 6 zahnborsten on third endite and two very large setae near first endite. T 2 without d-setae, penultimate segment divided, terminal segment with one long claw and two subapical setae, the latter unusually long in at least some species. T 3 with terminal segment separate from penultimate segment. Caudal ramus with distal seta.
