Diplotriaena delirae Pinto & Noronha, 1970 (Nematoda, Diplotriaenidae) in Pitangus sulphuratus (Linnaeus, 1766) (Passeriformes, Tyrannidae) from southern Brazil

Abstract

Diplotriaena delirae Pinto & Noronha, 1970 is known to parasitize Pitangus sulphuratus (Linnaeus, 1766) in Peru and in the Midwestern and Southeastern regions of Brazil. Here, specimens of P. sulphuratus were collected in the southern state of Rio Grande do Sul, Brazil, and necropsied. Nematodes (n = 6) found in these specimens were identified as D. delirae based on their morphological traits. This is the first report of D. delirae from southern Brazil, expanding the knowledge of the helminth fauna of P. sulphuratus in the Neotropical region.
