Contribuição ao conhecimento da fauna helmintológica na região Amazônica - Nematódeos

Abstract

Study 18 species as follows: TRICHOSTRONGYLOIDEA: Hassalstrongylus dessetae sp. n., Heligmostrongylus proechimysi Durette-Desset, 1970, Viannaia hamata Travassos, 1914, Molineus torulosus ( Molin, 1861) Yorke & Maplestone, 1926. OXYUROIDEA: Aspidodera raillieti Travasses, 1914, Aspidodera scoleciformis (Diesing, 1851) Railliet & Henry, 1912, Cruzia tentaculata ( Rudolphi, 1819) Travassos, 1917, Helminthoxys urichi Cameron & Reesal, 1951, Trypanoxyuris (Trypanoxyuris) minutus (Schneider, 1866) Inglis & Diaz-Ungria, 1960. OXYUROIDEA: Aspidodera raillieti Travasses, 1914, Aspidodera scoleciformis (Diesing, 1851) Railliet & Henry, 1912, Cruzia tentaculata ( Rudolphi, 1819) Travassos, 1917, Helminthoxys urichi Cameron & Reesal, 1951, Trypanoxyuris (Trypanoxyuris) minutus (Schneider, 1866) Inglis & Diaz-Ungria, 1960. FILARIOIDEA: Dipetalonema gracile (Rudolphi,1809) Diesing, 1861, Skrjabinofilaria skrjabini Travassos, 1925. SPIRUROIDEA: Leiuris pereirai Gomes & Vicente,1970, Paraleiuris vazi Vicente & Gomes, 1971, Pterygodermatites (Paucipectines) elegans (Travassos, 1928) Quentin, 1969, Spirura guianensis (Ortlepp, 1924) Chitwood, 1938, Gongylonema sp., Physaloptera sp. SUBULUROIDEA: Subulura-interrogans Lent & Freitas, 1935. Hassalstrongylus dessetae sp. n. Comes nearer to Hassalstrongylus epsilon (Travassos, 1937) Durette-Desset, 1971, and its discussion is based on the synlophe or fixation apparatus, found in numerous trichostrongyloids, specially the heligmosomes We redescribe the other species, ratifying their systematical position in an attempt to accomplish their original descriptions. For Aspidodera raillieti, Aspidodera scoleciformis, Cruzia tentaculata, Pterygodermatites (Paucipectines) elegans, Subulura-interrogans new host records are stablished. First occurrences in Brazil are verified for Hassalstrongylus proechimysi e Helminthoxys urichi. We could not obtain data enough to provide the specific diagnosis for Gongylonema sp. and Physaloptera sp. , due to the unsatisfactory condition of the samples. The captured Amazonian mammals are also listed.
