A NEW SPECIES OF EREBONECTES (COPEPODA, CALANOIDA) FROM MARINE CAVES ON CAICOS ISLANDS, WEST-INDIES

Erebonectes macrochaetus was collected from two anchialine caves on Ca icos Islands. This is the second species of the genus, and considerabl y smaller than its congener only known from caves in Bermuda. The most pronounced morphological differences between the two species are foun d in the furcal setae, mandible, first leg, and the fifth legs of the male. In E. macrochaetus one furcal seta on left side is extremely elo ngated, the endopod of mandible is reduced, and in first leg the first segment of endopod has an elongated process on its outer distal corne r.
