RESUMO
Petilipinnis, new genus, is proposed for Corvina grunniens Schomburgk, from the Amazon and Essequibo river basins. It is distinguishable from other Sciaenidae genera with the exception of Menticirrhus, by the presence of only one spine in the anal fin. From Menticirrhus, Petilipinnis differs by the morphology of the swimbladder and the number of dorsal fin soft rays. Also a redescription of Petilipinnis grunniens is presented.
