Pudicinae (Nematoda) coparasitic in Proechimys roberti (Rodentia: Echimyidae) from the Brazilian Amazonia: description of a new species of Pudica, redescription of Pudica evandroi (Travassos) and updated key to the species of the genus

Abstract: The re-examination of nematodes collected decades ago from a spiny rat, Proechimys roberti (Echimyidae) from Pará State, revealed the presence of Acanthostrongylus acanthostrongylusTravassos, 1937, and two coparasitic species of Pudica (Heligmonellidae: Pudicinae), one of them new to science. Pudica minima n. sp. mostly resembles Pudica tenuaDurette-Desset, 1970, described from Proechimys semispinosus in Colombia. Nevertheless, it differs from P. tenua by having a synlophe with 12 ridges with poorly developed careen, bursal pattern of type 2-2-1 on the right lobe, bursal rays 2 and ...
