| Leporinus obtusidens Valenciennes, 1837 and L. elongatus Valenciennes, 1850 are redescribed based on the type specimens, including those of their junior synonyms, and recently collected specimens. Leporinus obtusidens is considered to be widespread, occuring in the river drainages of La Plata, São Francisco, and Parnaíba. Leporinus aguapeiensis Campos, 1945, described from the upper Rio Paraná, and L. silvestrii Boulenger, 1902, described from the Rio Paraguay, are considered junior synonyms of L. obtusidens. Leporinus elongatus is endemic to the Rio Jequitinhonha and Rio Pardo, two eastern Brazilian river basins, and the locality cited for the lectotype, Rio São Fransico, likely to be erroneous. Leporinus crassilabris Borodin, 1929, and L. crassilabris... |

| Um estudo sobre a composição ictiofaunística do rio Quilombo foi realizado com o intuito de identificar quais espécies de peixes habitam a bacia, com que freqüência tais espécies são encontradas e verificar variações na distribuição longitudinal desta ictiofauna. Foram demarcados quatro pontos de coletas distribuídos na bacia, os quais foram visitados 21 vezes ao longo de um ano e dez meses (entre setembro de 2003 e junho de 2005), abrangendo os períodos seco e úmido que ocorrem anualmente na região estudada. Para coleta dos peixes foram utilizadas diferentes artes de pesca: tarrafas, redes de espera, rede de arrasto, peneiras, linha e anzol. Os peixes foram fixados em formalina 10%, conservados em etanol 70%, identificados e encontram-se depositados na... |

| This work aimed to study the composition and distribution of fish species at four sites along Cabeça River, an affluent of Corumbataí River, tributary of Tietê River, intending to better understand the influence of local geomorphology on the occurrence of the species along the river. Using gill nets, trawl net, cast net and sieves, five samples were taken from each site every two months. These data were analyzed from constancy of occurrence, similarity index of Jaccard, rarefaction analysis and descriptive statistical analysis of richness. 4,532 fish individuals belonging to six different orders, 17 families and 65 species were captured. Differences in composition, richness (diversity), abundance and frequency were observed at these sites along the river.... |

| ABSTRACT The species Rhamdia branneri Haseman, 1911 and the subspecies Rhamdia branneri voulezi Haseman, 1911 from rio Iguaçu are currently recognized as synonyms of Rhamdia quelen (Quoy & Gaimard, 1824). However, recent karyotype and ecomorphology studies distinguish R. branneri and R. voulezi as different species. Examination of Rhamdia populations from rio Iguaçu, including type specimens, together with other congeners from rio Tibagi, allowed to properly reexamine the situation of these Haseman's taxa and references given to Rhamdia in the Iguaçu. The species R. branneri and R. voulezi have strong serrae with large basis on both margins of the pectoral-fin spine, uncommon in the remaining species of Rhamdia and different from the fine serrate... |

| After several years collecting in the type-localities and studying representative samples of genus Steindachneridion Eigenmann & Eigenmann, 1919 from Brazilian and foreign museums, a taxonomic revision of the Recent species of the genus is presented, including the description of a new species from the rio Iguaçu, above the great falls. Steindachneridion species are large sized fishes, reaching 1000 mm total length or more, and sharing some anatomical characters that, at least tentatively, support the monophyly of the genus. In addition to the general features found in the Pimelodidae, the species S. amblyurum (Eigenmann & Eigenmann, 1888), S. parahybae (Steindachner, 1877), S. doceanum (Eigenmann & Eigenmann, 1889), S. scriptum... |
