Original description. Moenkhausia bonita Benine et al. 2004: 68   .

Material examined. BRAZIL • 9, 24.7−28.2 mm SL; São Paulo state, Pongaí, Ribeirão Sucurizinho ; 21°43′39″S, 049°18′54″W; 12 May 2018; leg. Silva G.S.C. and Reia L. ( LBP 26528 View Materials ) GoogleMaps   8, 15.6−29.5 mm SL; São Paulo state, Pon- gaí, Córrego Água Grande ; 21°41′31″S, 049°20′31″W; 12 May 2018; leg. Silva G.S.C. and Reia L. ( LBP 26511 View Materials ) GoogleMaps   .

Identification. Body deep; mouth terminal; premaxil- lary teeth in two rows, inner row with five to six tetrato pentacuspidate teeth, outer row with four tricuspidate teeth; one to three tricuspidate teeth on maxilla; dentary with four anteriormost teeth larger, tri- to pentacuspidate. Lateral line incomplete with eight to ten perforated scales; longitudinal series with 32 or 33 scales; six hor- izontal scale rows above lateral line; three horizontal scale rows below lateral line. Overall body coloration silver to yellowish; silver midlateral stripe from ante- rior margin of opercle faint to caudal peduncle; caudal peduncle with a black lozenge-shaped spot extending to first half of middle caudal-fin rays; distal margin of both caudal-fin lobes black, except for their tips; dorsal por- tion of eyes orange; fins yellowish to reddish.

Remarks. The specimens did not present a complete lateral line, as observed in the original description ( Benine et al. 2004). However, Vanegas-Ríos et al. (2019) analyzed populations of M. bonita   from the Bermejo, Paraná, Paraguay, and Uruguay basins and determined that observed differences in body shape and complete- ness of lateral line are intraspecific variations. Hemigrammus marginatus Ellis, 1911   was the name used for the specimens from upper rio Paraná; however, Ota et al. (2015) restricted this species to the basin of the rio São Francisco and rivers of northeastern Brazil. It is possible specimens of Hemigrammus marginatus   collected by Serra et al. (2015) are M. bonita   .
