First report of Pterinotrematoides mexicanum Caballero & Bravo-Hollis, 1955 (Monogenea, Macrovalvitrematidae) in Micropogonias furnieri (Desmarest, 1823) (Perciformes, Sciaenidae) from the coastal zone of the state of Rio Grande do Sul, Brazil

Abstract

: In South America, Pterinotrematoides mexicanum Caballero & Bravo-Hollis, 1955 has been reported in the state of Rio de Janeiro, Brazil, and in Argentina parasitizing Micropogonias furnieri (Des­marest, 1823). In this paper, the first record of P. mexicanum in the same host from the coastal zone of the state of Rio Grande do Sul, Brazil is presented, filling a gap of occurrence of P. mexicanum. The morphology of P. mexicanum is re­described and compared with that of Neopterinotrematoides avaginata Suriano, 1975.
