PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON 110(l):74-98. 1997. New records of marine Isopoda from Cuba (Crustacea: Peracarida) Brian Kensley, Manuel Ortiz, and Marilyn Schotte (BK & MS) Department of Invertebrate Zoology, National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560, U.S.A.; (MO) Centro de Investigaciones Marinas, Universidad de la Habana, La Habana, Cuba Abstract. — Seven new species are described from localities on both the north and south coasts of C ba: Cyathura (Cyathura) esquivel, Mesanthura frances, Joeropsis juvenilis, Joeropsis unidentata, Dynamenella nuevitas, Paraimene ibarzobalae, Paraimene tumulus. Several new records, including Carpias har-rietae, Caecijaera horvathi, and Sphaeromopsis mourei are noted. The material was collected from a range of habitats, including shallow coral reefs, man-groves, seagrass beds, coastal lagoons, river mouths, rocky and sandy shore inter-/and shallow infratidal areas. Knowledge of the marine, freshwater, and cave isopod fauna of Cuba has grown slow-ly, from the earliest records of two species of Aega by Schioedte & Meinert in 1879. Numerous short papers, often describing a single species, have accumulated over the years. The first cave isopod was described by Hay in 1903; since then several addition-al species especially in the genus Cyathura have been added to the list. Coineau & Bo-tosaneanu (1973) produced the only report on interstitial isopods from Cuba. Ortiz et al. (1987) provided an updated list of Cuban isopods along with a bibliography. From the relatively small number of species in this list, it is obvious that many more await dis-covery, as many regions of the island's shal-low and deep waters have not been collect-ed. In an attempt to fill some marine distri-butional gaps, and to document the diversity of several groups of shallow water marine organisms, two collecting trips, in April 1994, and May/June 1995, were carried out jointly by Cuban and Smithsonian Institution scientists. This work was sponsored chiefly by the Center for Marine Conservation, Washington, D.C. The 1994 trip was based aboard the R/V Ulises, which travelled along the north coast through the Archipielago de Camagiiey as far as Bahia de Nuevitas, stop-ping at several localities to carry out inten-sive sampling. The 1995 trip was to the south-western part of the island, mainly in the region around the Isla de la Juventud. The material reported in this paper was collected primarily by the authors, although several other individuals assisted. K-CUBA station numbers refer to field notes for the two trips. Holotypes have been deposited in the Centro Colecciones Naturales Marinas, Instituto de Oceanologia (IO), Havana, Cuba; paratypes and additional materials are deposited in both the CCNM and the Na-tional Museum of Natural History (USNM), Smithsonian Institution. An annotated checklist of the marine isopod fauna of Cuba is being compiled, based on a variety of sources of material. Dimensions in millimeters are always to-tal length measured along the dorsal midline.
