title: Cotylogaster basiri Siddiqi & Cable, 1960 (Aspidobothrea: Aspidogastridae) in Pogonias cromis (Linnaeus, 1766) (Perciformes: Sciaenidae): first report from Brazil.
abstract: Up until now, there have been few studies of the helminth fauna of Brazilian populations of Pogonias cromis. In North America, P. cromis is known to be a definitive host of Cotylogaster basiri, although there have been no reports of any species of Cotylogaster infecting fish in Brazil. During necropsies of marine fish obtained from professional fisherman in the state of Rio Grande do Sul, Brazil, specimens of C. basiri were found in the intestine and rectum of P. cromis. In comparison with previous studies, differences were found in relation to the number of lobes in the buccal disc and the development of the biocellate larvae in the eggs of C. basiri. This is the first report of C. basiri in P. cromis from Brazil, contributing to the understanding of the helminth fauna of this fish from the coastal zone of Brazil.
