Haliotrema (Monogenea: Ancyrocephalinae) from Ostraciid Fishes in Guadeloupe, West Indies

Six sympatric species of Haliotrema Johnston and Tiegs, 1922 are described from ostraciid fishes in Guadeloupe, West Indies. All have a basic cone-shaped cirrus, but characteristics of that and other terminal genitalia plus those of anchors can differentiate them: H. guadeloupensis sp. n. from Lactophrys triqueter (typehost) and L. bicaudalis; H. torridum sp. n. from L. triqueter (type-host) and Acanthostracion polygonius; H. glandulosum sp. n. from L. triqueter (type-host) and L. bicaudalis; H. minutum sp. n. from A. polygonius; H. lactophrys (MacCallum, 1915) comb. n. from A. polygonius and A. quadricornis which is transferred from the genus Ancyrocephalus Creplin, 1839; and H. kritskyi nom. nov. from A. polygonius. The latter has been given a replacement name for Parahaliotrema brevis. Mizelle and Kritsky, 1969 which would become a junior homonym because it, H. affinis (Mizelle and Kritsky, 1969) comb. n., H. cornutus (M. and K.) comb. n., H. grandis (M. and K.) comb. n., H. pacificus (M. and K.) comb. n., and H. zebrasoma (M. and K.) comb. n. are all transferred from the genus Parahaliotrema Mizelle and Price, 1964. We follow others in considering that genus to be a junior synonym of Haliotrema. We also determined that at least Ancyrocephalus parupenei Yamaguti, 1968 and A. pauu Yamaguti, 1968 do not belong in Ancyrocephalus. However, investigation of H. australe Johnston and Tiegs, 1922 and other species should precede transferring those species to another genus.
