description: <i>Moenkhausia bonita</i> Benine, Castro, Sabino, 2004 <b>Fig. 8</b> Body elongated; greatest depth contained 2.9 to 3.4 and caudal peduncle depth 8.5 to 9.5 times in SL; head length 3.5 to 3.9, predorsal distance 1.9 to 2.0 and caudal peduncle length 7.4 to 9.0 in SL; snout length 3.4 to 4.2, horizontal orbital diameter 2.0 to 2.4 and least interorbital width 3.0 to 3.5 in HL. Mouth terminal; inner row of premaxilla with 5 teeth, outer with 2-5, dentary with 4 and maxilla with 2 or 3 teeth. Lateral line complete with 29-31 pored scales, sometimes disrupted or incomplete 6 to 13 pored scales; longitudinal series with 29-31 scales; transverse series above lateral line with 5 scale rows and below with 3 scale rows. Dorsal fin with 11 rays, pectoral fin with 12-13 rays, pelvic fin with 8 rays, anal fin with 24-26 rays and caudal fin with 19 rays. Ground color silvery to pale yellow; darkbrown longitudinal stripe from opercle (conspicuously from vertical through dorsal-fin origin) to median caudal fin rays; distal portion of caudal fin lobes equally dark-brown. <b>Maximum standard length.</b> 43.8 mm. <b>Biological data.</b> Lives in marginal backwaters with low current speeds and feeds mainly on terrestrial insects (Diptera and Coleoptera) (Benine <i>et al.</i>, 2004). <b>Distribution.</b> Upper rio Paraná and río Paraguay basins. <b>Remarks.</b> Some specimens of <i>Moenkhausia bonita</i> were identified as <i>Hemigrammus marginatus</i> by Graça, Pavanelli (2007), who reported some specimens with lateral line completely pored, and others with lateral line disrupted or incompletely pored.R. P.Ota andA. G. Bifi (oral communication, 2009) were the first to identify <i>M. bonita</i> in the upper rio Paraná floodplain, formelly restricted to the type-locality (Baía Bonita) in its original description (Benine <i>et al.</i>, 2004). <i>Hemigrammus marginatus</i> was restricted the distribution of <i>H. marginatus</i> to the rio São Francisco basin and rivers of northeastern Brazil by Ota, RP <i>et al.</i> (2015). Mota <i>et al</i>. (2018, in press), in a molecular analysis, concluded that the specimens from the upper rio Paraná floodplain, including those with variation in lateral line (complete, disrupted and incomplete), belong to <i>M. bonita.</i>
