A New Cave Amphipod (Crustacea) from Curacçao: Psammogammarus Caesicolus n. sp.

Abstract

A new species of Amphipoda, Psammogammarus caesicolus , is described from interstitial, anchihaline waters in Blauwbaai cave, Curaçao, Netherlands Antilles. By the morphology of the third uropod, the new species links the somewhat aberrant Ps. longiramus from the Red Sea with the type-species of the genus, Ps. coecus , from the Mediterranean.
