Abstract

A new species of Remipedia (Crustacea), Speleonectes emersoni, is described from two anchialine caves in the Dominican Republic. It represents the first record of remipedes for the island of Hispaniola. Speleonectes emersoni is a comparatively small-sized remipede. It can be distinguished from other species in the genus Speleonectes by a combination of features that include: 1) a relatively large antennal exopod, 2) frontal filaments with subapically inserted medial processes extending over the tip of the main filament, 3) an arc-shaped horseshoe-type claw with 7–10 small denticles, and 4) an anal segment that is longer than wide with caudal rami nearly as long as the anal segment.
