Ostracods are one of the major groups of marine benthos, inhabiting virtually all oceanic environments worldwide, and a total of 31 species have been recorded in genus Euphilomedes Kornicker, 1967. In the present study, we describe a new species Euphilomedes

Ostracods are small bivalved crustaceans widely distributed in aquatic environments and in total 99 species have been recorded in genus Euphilomedes Kornicker, 1967. In this study, we further describe two new species of benthic ostracods in this genus,

A new species of Philomedidae is described: Euphilomedes chupacabra from coastal Puerto Rico. This is the first described species of Euphilomedes from the Western Atlantic, a genus of particular interest for its sexually dimorphic lat-eral eyes. As
