Mouth terminal, slightly prognathous; premaxilla with 4-8, dentary with 9-23 and maxilla with 8-17 teeth. Lateral line incomplete, with 8-13 pored scales; longitudinal series with 36- 42 scales; transverse series above lateral line with 5-7 scale rows and below with 3-4 scale rows. Dorsal fin with 9-11, pectoral fin with 10-14, pelvic fin with 7-8, anal fin with 16-22, and caudal fin with 19 rays ( Lima, 2003 ). Ground color silvery; diffuse, oval transversely elongated, humeral spot; no other black marks on body and fin. Caudal fin red, other fins hyaline to yellowish ( Graça, Pavanelli, 2007 ). Maximum standard length. 60.0 mm ( Graça, Pavanelli, 2007 ). Distribution. Paraná-Paraguay system. Remarks. Aphyocharax dentatus is a non-native species from the upper rio Paraná and its occurence can be associated with the filling of the Itaipu Reservoir and the consequent inundation of the Sete Quedas Falls ( Graça, Pavanelli, 2007 ).
