PROC. BIOL. SOC. WASH. 94(4), 1981, pp. 1005-1047 NINE NEW SPECIES OF ANILOCRA (CRUSTACEA: ISOPODA: CYMOTHOIDAE) EXTERNAL PARASITES OF WEST INDIAN CORAL REEF FISHES Lucy Bunkley Williams and Ernest H. Williams, Jr. Abstract. — Nine new species of Anilocra are described: A. haemuli from Haemulon flavolineatum, H. aurolineatum, H. carbonarium, H. chrysar-gyreum, H. macro stomum, H. plumieri, H. sciurus, Epinephelus cruenta-tus, E.fulvus, E. guttatus, and Paranthias furcifer; A. holocentri from Hol-ocentrus ascensionis; A. myripristis from Myripristis jacobus; A. acanthuri from Acanthurus chirurgus, and A. bahianus; A. chromis from Chromis multiline atus and C. cyaneus; A. abudefdufi from Abudefduf saxatilis; A. holacanthi from Holacanthus tricolor; A. chaetodontis from Chaetodon capistratus, C. ocellatus, C. sedentarius, and C. striatus; and A. partiti from Pomacentrus partitus. Anilocra laticauda Milne Edwards, 1840 and A. leachii Schioedte, 1866 are declared nomina dubia. The Martinique and Peru specimens of A. laevis are shown to represent 2 species: A. haemuli and A. laevis, respectively. A table distinguishing the species of genus Anilocra in the Caribbean Sea is included. Introduction Six species in the genus Anilocra Leach, 1818, have been described from the New World, A. laticauda Milne Edwards, 1840; A. mexicana Saussure, 1857; A. laevis Miers, 1877; A. plebeia Schioedte and Meinert, 1881; A. acuta Richardson, 1910; and A. meridionalis Richardson, 1914. Schioedte and Meinert (1881) synonymized A. mexicana Saussure and A. laticauda Milne Edwards; and Trilles (1975) suggested A. laevis Miers was a synonym of A. laticauda. Various other authors, summarized by Trilles and Vala (1975), have reported Anilocra laticauda from members of 11 families of marine fishes in the Caribbean Sea. Hochberg and Ellis (1972) and Williams and Williams (1977) have suggested that other species of Anilocra occur in the Caribbean. In the present study 1379 specimens of isopods in the genus Anilocra from the West Indies were examined (1198 were collected by the authors from 823 fishes) and separated into 9 species based on the characters fisted in Table 1. Materials and Methods Host fishes were individually collected with multiprong and conventional spears, quinaldine fish relaxant, or handheld nets and lights at night, using
