Body deep and compressed; greatest depth contained 2.1 to 2.5 and caudal peduncle depth 9.7 to 10.8 times in SL; head length 3.4 to 4.0, predorsal distance 1.9 to 2.1; snout length 3.5 to 4.0, horizontal orbital diameter 2.3 to 2.8 and least interorbital width 2.6 to 3.2 in HL. Mouth terminal; inner row of premaxilla with 5 teeth, outer with 3-5, dentary with 8-11 and maxilla with 1 tooth. Lateral line irregular (incomplete, rarely complete); longitudinal series with 40-45 scales.

Ground color whitish; diffuse black humeral spot; dark-brown rounded blotch on distal portion of caudal peduncle and caudal-fin base. Hyaline fins ( Graça, Pavanelli, 2007).

Maximum standard length. 45.5 mm ( Graça, Pavanelli, 2007).

Distribution. Paraná-Paraguay system and rio São Francisco basins.

Remarks. Psellogrammus kennedyi is a non-native species from the upper rio Paraná and its occurrence can be associated with the functioning of the Canal da Piracema (a fish ladder that connects the region downstream from the Itaipu Dam to the region upstream from the dam).
