Resumo: 	Neoplecostomus jaguari, a new neoplecostomine, is described based on material from the rio Jaguari, rio Tietê basin, southeastern Brazil. The new species differs from all congeners by having a conspicuous sexual dimorphism: females with 30-38 teeth in the dentary and 30-39 in the premaxilla, and males with 13-18 and 14-20 teeth, respectively (vs. number of teeth in the dentary and premaxilla approximately equivalent in all other species, except for N. langeanii in the premaxilla); females with larger mandibullary width, 18.5-21.6% HL, males 11.8-15.7% HL (vs.mandibullary width in males and females approximately equivalent); females with teeth longer and thin, males with teeth shorter and robust (vs. teeth similar in other species, except for N. langeaniiin the premaxilla). Furthermore the new species is distinguished from all other species from the upper rio Paraná basin by having a lateronasal plate either forming the border of the nostril or posteriorly displaced (vs. lateronasal plate absent). Finally, other useful character includes four to six plates between the frontal and prefrontal, herein called posteronasal plates (vs.one to three in all other species). An identification key to all Neoplecostomus species is provided.
