description: <b> <i>Moenkhausia forestii</i> Benine, Mariguela, Oliveira, 2009</b> <b>Fig. 8</b> Body deep; greatest depth contained 2.2 to 2.6 and caudal peduncle depth 7.4 to 8.7 times in SL; head length 3.2 to 3.7, predorsal distance 1.7 to 1.9 and caudal peduncle length 9.4 to 13.9 in SL; snout length 3.0 to 4.0, horizontal orbital diameter 2.3 to 2.9 and least interorbital width 2.3 to 2.7 in HL. Mouth terminal; inner row of premaxilla with 5 teeth, outer with 3-5, dentary with 11 and maxilla with 1 or 2. Lateral line incomplete, with 7-11 pored scales; longitudinal series with 23-26 scales; transverse series above lateral line with 5 scale rows and below with 4 scale rows. Dorsal fin with 11 rays, pectoral fin with 12 or 13 rays, pelvic fin with 8 rays, anal fin with 21-27 rays and caudal fin with 19 rays. Ground color silvery; superior portion of eye red; scales with darkbrown border, conferring reticulated pattern to body; one dark-brown humeral spot; dark-brown longitudinal stripe along posterior half of flank; anterior half of caudal peduncle with light-beige area. Hyaline fins, except caudal fin; posterior portion of caudal peduncle and proximal third of caudal fin with conspicuous black transverse bar occupying their whole depth. <b>Maximum standard length.</b> 36.4 mm. <b>Biological data.</b> Males present small hooks on the segments of each anal-fin ray (Benine <i>et al.</i>, 2009). <b>Distribution.</b> Upper rio Paraná and río Paraguay basins. <b>Remarks.</b> Some specimens of <i>Moenkhausia forestii</i> were identified as <i>M.</i> aff. <i>sanctaefilomenae</i> by Graça, Pavanelli (2007). Both species occur in the upper rio Paraná floodplain, where <i>M. forestii</i> has been captured since 2009 by Nupélia staff. <i>Moenkhausia forestii</i> can be distinguished by having transverse series above lateral line with 5 and below with 4 scale rows (<i>vs</i>. 4 scale rows above and 3 below, in <i>M. sanctaefilomenae</i>). Additionally, <i>M. forestii</i> can be distinguished from <i>M. australe</i>, another similar species, by having lateral line incompletely pored, transverse series above lateral line with 5 and below with 4 scale rows, and upper jaw length 39.9-44.0% HL (<i>vs.</i> lateral line completely pored, 4 scale rows above and 3 below, and upper jaw length 46.4-52.6% HL). Despite the general morphological similarity between <i>M. australe</i>, <i>M. forestii</i> and <i>M. sanctaefilomenae</i>, Benine <i>et al.</i> (2009) and Mariguela <i>et al</i>. (2013), in molecular analyses, considered them as different species. <i>Moenkhausia forestii</i> is a non-native species from the upper rio Paraná basin, and its recent 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 (Benine <i>et al.</i>, 2009).
