This genus America that ranges from the Atrato River, western is widespread in South America, including its south Colombia, down south to central portions of Argentina portion where they are mainly distributed in the São [1]. A hypothesis of phylogenetic relationships within Francisco and La Plata basins. Here we obtained the Anostomidae was recently proposed by Sidlauskas & sequences of mitochondrial and nuclear genes of 19 Vari [2], who recognize that the family includes fourteen species of Leporinus with the objective of testing our genera. Leporinus is the largest genus of Anostomidae methods of molecular species identification and to both in number of species and number of individuals test the similarities between species of Leporinus of in the rivers where they occur [1,3]; because of this, the São Francisco and La Plata basins. Results show several attempts were made trying to divide the species that two species pair have a genetic distance below of Leporinus in smaller groups. Fowler [4] created the 2% (L. paranensis x L. obtusidens and L. paranensis x subgenus Myocharax, based on the dentition presented L. aff. paranensis). Our results also show that a high by Leporinus desmotes, which shows a very long pair genetic distance occurs in L. obtusidens and L. striatus of symphyseal teeth. Borodin [5] attempted to divide suggesting a possible local differentiation of these the genus Leporinus in two subgenera and created species. An interesting finding of our study is that the subgenus Hypomasticus that included species the genetic similarities observed among species does with a lower mouth. Another subgenus, Leporinops, not corroborate the division of species of Leporinus in was created by Géry [6], based on tooth and cranial groups according to color patterns. Additionally, our differences. This subgenus was based on Leporinus results show that the species of Leporinus from the La moralesi [7]. All these proposals were not accept by Plata and São Francisco are not more similar among Garavello & Britski [1] in the catalog of species of the themselves than to species of other drainages which family but Hyposmastictus was recognized as valid by could be explained by the occurrence of recent fauna Sidlauskas & Vari [2]. exchanges between these two basins and adjacent Garavello & Britski [8], in a paper describing Leporinus basins. amblyrhynchus and L. paranensis from the upper Paraná Basin, showed that most species of the genus may be Keywords: Phylogeny, Molecular systematics, placed into three artificial groups based on the color Sequencing, Mitochondrial DNA, Fish. pattern of the trunk: 1) barred species, 2) striped species and 3) spotted species.

    Neotropical Ichthyology, 12(2): 317-326, 2014 Copyright © 2014 Sociedade Brasileira de Ictiologia DOI: 10.1590/1982-0224-20130114 Redescription of Leporinus jamesi (Characiformes: Anostomidae), a poorly known species of Leporinus from the lowlands of the central Amazon, Brazil Júlio C. Garavello1, Heraldo A. Britski2 and José L. O. Birindelli3 The poorly known Leporinus jamesi is redescribed. The species was originally described based on a single specimen collected in the rio Solimões at Manacapuru, in the central Amazon, Brazil. The holotype went missing before the species description was finished and published, and remained lost for more than a hundred years.Leporinus jamesi is distinguished from its congeners by having pectoral and pelvic fins dark, 42 to 45 scales on the lateral line, 16 scale series around the caudal peduncle, a body with two conspicuous dark midlateral blotches (the blotch on the caudal peduncle absent or inconspicuous), and four teeth on the premaxilla and dentary, including a bicuspid symphyseal tooth on the premaxilla. A principal component analysis on morphometric traits between combined samples of L. jamesi and L. amazonicus was performed showing significant morphometric differences between these species. In addition, inaccuracies in Borodin’s descriptions of various species of the genus Leporinus are discussed. Leporinus jamesi, uma espécie pouco conhecida, é redescrita. A espécie foi originalmente descrita com base em um único exemplar procedente do rio Solimões em Manacapuru, na Amazônia central, Brasil. O holótipo da espécie foi perdido antes de sua descrição ter sido concluída e publicada, assim permanecendo por mais de cem anos. Leporinus jamesi distingue-se dos congêneres por apresentar as nadadeiras peitorais e pélvicas escuras, 42 a 45 escamas na linha lateral, 16 séries de escamas ao redor do pedúnculo caudal, duas manchas escuras conspícuas na lateral do corpo (mancha do pedúnculo caudal ausente ou inconspícua) e quatro dentes no pré-maxilar e no dentário , incluindo um dente bicúspide sinfisiano.

    Check List of the Freshwater Fishes of Uruguay (CLOFF-UY)

    Ichthyological Contributions of PecesCriollos 28: 1-40 (2014) 1 Check List of the Freshwater Fishes of Uruguay (CLOFF-UY). Thomas O. Litz1 & Stefan Koerber2 1 Friedhofstr. 8, 88448 Attenweiler, Germany, [email protected] 2 Friesenstr. 11, 45476 Muelheim, Germany, [email protected] Introduction The purpose of this paper to present the first complete list of freshwater fishes from Uruguay based on the available literature. It would have been impossible to review al papers from the beginning of ichthyology, starting with authors as far back as Larrañaga or Jenyns, who worked the preserved fishes Darwin brought back home from his famous trip around the world. The publications of Nion et al. (2002) and Teixera de Mello et al. (2011) seemed to be a good basis where to start from. Both are not perfect for this purpose but still valuable sources and we highly recommend both as literature for the interested reader. Nion et al. (2002) published a list of both, the freshwater and marine species of Uruguay, only permitting the already knowledgeable to make the difference and recognize the freshwater fishes. Also, some time has passed since then and the systematic of this paper is outdated in many parts. Teixero de Mello et al. (2011) recently presented an excellent collection of the 100 most abundant species with all relevant information and colour pictures, allowing an easy approximate identification. The names used there are the ones currently considered valid. Uncountable papers have been published on the freshwater fishes of Uruguay, some with regional or local approaches, others treating with certain groups of fishes.

We analyzed a small and wide geographically distributed Neotropical freshwater fish, the Piabina argentea from the Upper Parana´ Basin, to check the hypothesis that this species is composed of more than one biological unit, since it has a limited dispersion, through the DNA barcode technique. Materials and methods. Partial mitochondrial COI and CytB gene sequences were obtained for 58 specimens drawn from 13 localities. Results. Phylogenetic analysis revealed six major clusters of P. argentea. Kimura-two-parameter (K2P) genetic divergences among these six P. argentea clusters ranged from 2 to 5.6% and from 2.3 to 5.4% for COI and CytB genes, respectively, and these values were on average approximately nine times greater than intra-cluster K2P divergences. The fixation index (FST) among clusters showed very high values and the haplotype network analysis displayed seven unconnected units. Conclusion. These results reinforce the hypothesis that the For personal use only. widely distributed P. argentea species concept as currently conceived actually represents more than one species (possibly six).

Both species shared (i) a diploid chromosome number 2n = 48 and the karyotype structure, (ii) low amount of constitutive heterochromatin, (iii) the absence of interstitial telomeric sites (ITSs), (iv) a single pair of 5S rDNA loci adjacent to one major rDNA cluster, and (v) a single pair of co-localized U1/U2 snDNA tandem repeats.

    Cytogenetic and Molecular Markers Reveal the Complexity of the Genus Piabinareinhardt, 1867 (Characiformes: Characidae)

    Neotropical Ichthyology, 10(2): 329-340, 2012 Copyright © 2012 Sociedade Brasileira de Ictiologia Cytogenetic and molecular markers reveal the complexity of the genus Piabina Reinhardt, 1867 (Characiformes: Characidae) Marlon Felix Pazian, Luiz Henrique Garcia Pereira, Cristiane Kioko Shimabukuru-Dias, Claudio Oliveira and Fausto Foresti Cytogenetic and molecular analyses were carried out in fish representative of the genus Piabina. This study specifically involved the species P. argentea and P. anhembi collected from areas of the Paranapanema and Tietê River basins, Brazil. Our findings suggest that fish classified as Piabina argentea in the Paranapanema and Tietê Rivers may represent more than one species. The samples analyzed differed by cytogenetic particularities and molecular analyses using partial sequences of the genes COI and CytB as genetic markers revealed three distinct groups of P. argentea with genetic distances sufficient to support the conclusion that the three samples analyzed are three distinct taxonomic units. Foram realizadas análises citogenéticas e moleculares em representantes do gênero Piabina. O estudo envolveu especificamente as espécies P. argentea e P. anhembi coletadas nas áreas das bacias hidrográficas dos rios Paranapanema e Tietê (Brasil). Os dados sugerem que a espécie P. argentea coletada nas bacias dos rios Paranapanema e Tietê podem representar mais de uma espécie. As amostras analisadas diferem por particularidades citogenéticas e nas análises moleculares utilizando-se sequências parciais dos genes COI e CytB, revelando três grupos distintos de P. argentea com distâncias genéticas suficientes para sustentar a conclusão de que as três amostras analisadas são unidades taxonômicas distintas.
