ABSTRACT Between April 1987 and April 1990, 45 species of marine isopods were collected from
intertidal and subtidal habitats in the vicinity of Pine Cay, Turks and Caicos, British West Indies. Five
species, Licranthura tuberculata, Mesanthura spongicola, Califanthura minuta, Stenetrium caicoensis, and
Armadilloniscusstepus,areknowncurrentlyonlyfromthenortheasternTurksandCaicosIslands. TheTurks
and Caicos collections represent considerable range extensions for many of the species collected. Four
species, Apanthura cracenta, Mesanthura punctillata, Carpias triton, and Munna petronastes, known
previously from tlie east coast of Central America (Belize), are reported for the first time since their
description. This report also presents the first publi.shed records from outside of their respective type
localities for Amakusanthura significa, Mexicope kensleyi, Carpias brachydactylus, Carpias serricaudus,
Uromunna caribea, Stenetrium monocule, and Stenobermuda acutirostrata. The other species reported,
mostly flabelliferans, appear to be widely distributed in the tropical western North Atlantic and their
occurrence in the Turks and Caicos was not unexpected.
