Branchiosyllis salazari n. sp. (Polychaeta, Syllidae) from Northwestern Carribean with notes on type material of B. exilis (Gravier, 1900)On the basis of 195 specimens from the Northwestern Caribbean Sea, a new species of Branchiosyllis Ehlers, 1887 is described. Branchiosyllis salazari n. sp. has three pairs of eyes (two small pairs above the anterior margin of the prostomium, the third pair in a tansverse line), without branchia, setae with large hooked blades in median setigers, and proventricle without middorsal line. The type material of B. exilis (Gravier, 1900), an apparently circumtropical species, was revised to clarify its presence in the Caribbean Sea. Its diagnostic features are: two pairs of eyes in a transverse line, no branchia, setae with large hooked blades in posterior setigers only, and proventricle with a middorsal line of Diamond-shaped cells. A key for the seven species of Branchiosyllis in the Grand Caribbean is included.
