Composition. 14 taxa currently recognized, plus one described herein, distributed mainly in coastal anchialine and marine shallow-water interstitial habitats of Japan, Indonesia, the Red Sea, Mediterranean, Cape Verde and Canary archipelagos, the Dutch Antilles, the Caribbean coast of Nicaragua, and Baja California (Table 1; Vonk et al. 2011, and references therein).

Remarks. Vonk et al. (2011) recently reviewed the main features of members of the so-called Eriopisa -group. The foregoing generic re-diagnosis is based on data provided by these authors, complemented with features of the new species described herein.
