ABSTRACT<\/strong><\/p>\n

A new species of the characid genus\u00a0Knodus<\/em>\u00a0is described from the rio Aripuan\u00e3 (rio Madeira basin). It can be distinguished from its congeners by its very low body depth, the presence of tri- to pentacuspid teeth on the outer premaxillary series, with the median cuspid larger than the lateral ones, the teeth of the inner premaxillary series pentacuspid, distinctly larger than those of the outer series, the maxillary teeth tri- to pentacuspid, with the median cusp slightly larger than the lateral ones, the four anteriormost dentary teeth pentacuspid, the smaller posterior teeth tri- to pentacuspid, a complete lateral line with 36-38 scales, 3 longitudinal scale series from pelvic fin origin to lateral line, and 11-12 circumpeduncular scales. The new species is also compared to\u00a0incertae sedis<\/em>\u00a0species of \u2018Bryconamericus<\/em>\u2019 from northern South America since phylogenetic studies suggest a closer relationship of those species with\u00a0Knodus<\/em>.<\/p>\n
