| ABSTRACT Diaphorocleidus altamirensis sp. nov., parasitic on the gills of Argonectes robertsi Langeani, 1999 from the Xingu River, northern Brazil, is described. The new species differs from its six congeners by the morphology of the male copulatory organ (which comprises a coil of six rings), by the midventral vagina, and by the presence of only one pair of eyespots. It is the first species of Diaphorocleidus Jogunoori, Kritsky & Venkatanarasaiah, 2004 described from hemiodontid fishes. In addition, new host and geographical records of seven species of dactylogyrids found on fish from the Xingu River are reported. |

| ABSTRACT During a survey of helminth parasites of the brown ground snake, Atractus major Boulenger, 1894 (Serpentes: Dipsadidae) from Moyobamba, region of San Martin (northeastern Peru), a new species of Glossidiella Travassos, 1927 (Plagiorchiida: Plagiorchiidae) was found and is described herein based on morphological and ultrastructural data. The digeneans found in the lung were measured and drawings were made with a drawing tube. The ultrastructure was studied using scanning electron microscope. Glossidiella peruensis sp. nov. is easily distinguished from the type- and only species of the genus, Glossidiella ornata Travassos, 1927, by having an oblong cirrus sac (claviform in G. ornata), distinctly ovate testes (rounded testes in G. ornata) and... |

| Fifty-five specimens of bluefish, Pomatomus saltator (Linnaeus, 1766), collected at Cabo Frio (23ºS, 42ºW), State of Rio de Janeiro, Brazil, between March 1995 and November 1995, were necropsied to study their infracommunities of metazoan parasites. Sixteen species of metazoan parasites were collected. All fish were parasitized by one or more metazoan. The digeneans were the majority of the parasite specimens collected, with 44.2%, followed by the helminth larval stages (cestodes, acanthocephalans, and nematodes) with 40.6%. The Simpson index for all parasite species was 0.097, indicating lack of dominance by any species in the parasite community. Microcotyle pomatomi Goto, 1899 showed the higher frequency of dominance and mean relative dominance. The... |

| Sixty specimens of Caranx hippos (Linnaeus, 1766) and fifty-five specimens of Caranx latus Agassiz, 1831 collected from the coastal zone of the State of Rio de Janeiro (21-23ºS, 41-45ºW), Brazil, from October 1998 to October 1999, were necropsied to study their metazoan parasites. All specimens of C. hippos were parasitized, and the majority of specimens of C latus (96.4%) were parasitized by one or more metazoan species. Nineteen species of parasites were collected in C. hippos: 5 digeneans, 5 monogeneans, 2 cestodes, 5 nematodes, and 2 copepods. Seventeen species of parasites were collected in C. latus: 6 digeneans, 2 monogeneans, 3 cestodes, 4 nematodes, and 2 copepods. The endoparasites (digeneans, cestodes, and nematodes) were the majoriry, 76.4% and... |

| Two species of Lepeophtheirus Nordmann, 1832 parasitic on the ariid fish Netuma barba Lacépède, 1803, and the bothiid fish Paralichthys sp. from the coastal zone of the State of Rio de Janeiro, are redescribed and illustrated: L. bagri Dana, 1852, and L. monacanthus Heller, 1865. New junior synonyms for these species are proposed: L. marginatus syn.n., L. christianensis syn.n. and L. platensis syn.n. of L. bagri and L. unispinosus syn.n. of L. monacanthus. |
