Abstract

Five species of amphibians, Leptodactylus podicipinus, Scinax acuminatus, S. nasicus, Rhinella fernandezae and Pseudis paradoxa, were collected in Corrientes province, Argentina and searched for larval nematodes. All larval nematodes were found as cysts in the serous of the stomach of hosts. Were identified one superfamily, Seuratoidea; one genus, Spiroxys (Superfamily Gnathostomatoidea) and one family, Rhabdochonidae (Superfamily Thelazioidea). We present a description and illustrations of these taxa. These nematodes have an indirect life cycle and amphibians are infected by consuming invertebrate, the intermediate hosts. The genus Spiroxys and superfamily Seuratoidea were reported for the first time for Argentinean amphibians.Cinco espécies de anfíbios, Leptodactylus podicipinus, Scinax acuminatus, S. nasicus, Rhinella fernandezae e Pseudis paradoxa, foram coletadas na província de Corrientes, Argentina e pesquisadas para achar nematoides larvais. Todas as larvas foram encontradas como cisto na serosa do estômago dos hospedeiros. Foram identificadas uma superfamília, Seuratoidea, um gênero, Spiroxys (Superfamília Gnathostomatoidea) e uma família, Rhabdochonidae (Superfamília Thelazioidea). Apresentamos uma descrição e ilustrações dos táxons. Estes nematoides têm um ciclo de vida indireto e os anfíbios são infectados pelo consumo dos invertebrados, os hospedeiros intermediários. O gênero Spiroxys e a superfamília Seuratoidea são relatados pela primeira vez para anfíbios da Argentina.
