Instituto Oswaldo Cruz. Rio de Janeiro, RJ, Brasil / Uma nova espécie da família Olig ancanthorhynchidae (Acanthocephala) Phosthenochis sp. foi coletada do intestino delgado do cachorro - do - mato Cerdocyon thous Linnaeus, 1766 (Canidae: Carnivora) no bioma Pantanal e descrita através da microscopia de luz e eletrônica de varredura. Caracterí sticas diferenciam esta espécie das demais descritas para este gênero, tais como tamanho do corpo, posição do leminisco, tamanho do ovo, hospedeiro e distribuição geográfica. Características morfológicas obtidas por microscopia eletrônica de varredura, com o presença de duas papilas laterais no pescoço, a presença de farpas nos ganchos e de colar festonado auxiliaram a identificação da espécie. Adicionalmente, foi depositado no GeneBank a seqüência obtida através do gene ribossomal 18S. As análises por micr oscopia de luz e eletrônica de varredura e moleculares adicionam infomações importantes para estudo da taxonomia deste grupo. Palavra chave: Helminto , A canthocephala, Prosthenorchis, cachorro - do- mato, Pantanal / A new species of Oligancanthorhynchidae (Achant h ocephala) Phosthenochis sp. is described from specimens collected from the small intestine of the crab - eating fox Cerdocyon thous Linnaeus, 1766 (Canidae: Carnivora) in the Brazilian Panta nal wetland and the new species were analyzed by light and scanning electron microscopy. Characteristic features distinguishing the new species from others already described were obtained, such as size of the body, the leminici position, size of the eggs, host and geographical distribution. Therefore, details of the surface body such as the presence of two lateral papillae in the proximal region of the proboscis, the presence of barbs in hooks and robust and festooned collar obtained by scanning electron mi croscopy helped to identify the species. In addition, the DNA sequence of the new species by 18S ribosomal gene was deposited in GeneBank. The analyses based on light microscopy and scanner electron microscopy, as well as the molecular analyses helped to o btain important information for the taxonomic study of the group.
