Abstract

Specimens of Periclimenes mclellandi, new species, were collected from gorgonians, primarily Pseudopterogorgia americana Gmelin, at depths of 14 to 43 m off Pine Gay, Turks and Caicos Islands, British West Indies. The new species belongs to the ''iridescens'' complex and is similar to P. patae Heard & Spotte, 1991, also associated with gorgonians at Pine Cay and the Florida Keys, but at shallower depths. Periclimenes mclellandi is distinguished from P. patae by a bilobate endite on the second maxillae, two rows of combsetae on the propodus of fifth pereopods, shorter and deeper rostrum with fewer rostral teeth, and an overall greenish coloration in Life. Both species are distinguished from other described members of the ''iridescens'' complex by the chelae of the second pereopods, which are similar and equal or nearly equal in size, and by the dactyls of pereopods 3-5, which are simple instead of biunguiculate. Some specimens of P. mclellandi were parasitized by an unidentified aceolid trematode metacercaria and an undescribed bopyrid isopod.
