Moenkhausia rubra, a new species from rio Juruena, upper rio Tapajós basin, Brazil (Characiformes: Characidae)

Moenkhausia rubra, new species, is described from the upper rio Juruena, rio Tapajós basin, Mato Grosso, Brazil. The new species is distinguished from its congeners, except M. hemigrammoides and M. nigromarginata, by the dark pigmentation on the anteriormost rays of both dorsal and anal fins. Moenkhausia rubra is distinguished from the aforementioned species by the number of branched anal-fin rays 17-20 (vs. 20-25), presence of a dark blotch on the caudal peduncle extending to middle caudal-fin rays, absence of longitudinal black zigzag stripes between longitudinal rows of scales on body, and other details of coloration.Moenkhausia rubra, espécie nova, é descrita do alto rio Juruena, bacia do rio Tapajós, Mato Grosso, Brasil. A espécie nova diferencia-se de todos os congêneres, exceto M. hemigrammoides e M. nigromarginata, pela presença de pigmentação escura nos raios mais anteriores das nadadeiras dorsal e anal. Moenkhausia rubra distingui-se das espécies acima mencionadas pelo número de raios ramificados na nadadeira anal 17-20 (vs. 20-25), presença de uma mancha escura no pedúnculo caudal se estendendo até os raios medianos da nadadeira caudal, ausência de faixas em zigue-zague longitudinais entre as séries longitudinais de escamas no corpo, além de outros detalhes de coloração.

“…But evidence of faunistic mixing in shield rivers have accumulated in recent years as well. For the most part, they involve adjacent drainages: Tapajós and Paraguay (Shibatta, Pavanelli, 2005;Lima et al, 2007;Birindelli, Britski, 2009;Tapajós, Xingu (Campos-da-Paz, 1999;Birindelli et al, 2008;Menezes et al, 2009);Tapajós, Madeira (Netto-Ferreira, Vari, 2011;Varella et al, 2012); Xingu, Paraguay (Vari, 1991;da Graça et al, 2008;Aquino, Schaefer, 2010;Netto-Ferreira, Vari, 2011); Xingu, Tocantins (Zawadzki et al, 2008;Ingenito et al, 2013); Tocantins, Paraguay (Lucinda, 2005;); Tocantins, São Francisco (Vari, Harold, 2001;Lima, Caires, 2011;Dagosta et al, 2014;Freitas et al, 2015); Tocantins, Upper Paraná (Britski,1997;Lima, Caires, 2011); Madeira, Paraguay (Kullander, 1982;Reis, Malabarba, 1988;Kullander, 2003;Vari et al, 2005;Vera-Alcaraz et al, 2012;Ota et al, 2014); Madeira and Juruena (Dagosta et al, 2016). In all such examples, the hypothesis that ancestral populations of trans-basin taxa were once widespread in the two basins concerned can be refuted because the current watershed divide between them dates from the Precambrian and vastly predate the radiations of Teleostei in the Upper Cretaceous (c. 100-66 Ma) and predate also the origin of the basins themselves .…”

Biogeography of Amazonian fishes: deconstructing river basins as biogeographic units

2017

Biogeography of Amazonian fishes (2,500 species in vastly disjunct lineages) is complex and has so far been approached only partially. Here, we tackle the problem on the basis of the largest database yet on geographical distribution and phylogenetic relationships of Amazonian fishes, including all information available. Distributions of 4,095 species (both Amazonian and outgroups) and 84 phylogenetic hypotheses (comprising 549 phylogenetically-informative nodes) were compiled, qualified and plotted onto 46 areas (29 Amazonian and 17 non-Amazonian). The database was analyzed with PAE, CADE, BPA and BPA 0 , yielding largely congruent results and indicating that biogeographic signal is detectable on multiple dimensions of fish distribution, from single species ranges to cladistic congruence. Agreement is especially pronounced in deeper components, such as Trans-Andean, Cis-Andean, Western Amazon and Orinoco basins. Results show that all major Amazonian tributaries, as well as the Amazon basin itself, are non-monophyletic and constitute hybrid sets of heterogeneous biotic partitions. Amazonian drainages should not be assumed a priori as historically cohesive areas, contrary to widespread practice. Our hypothesis allows reevaluation of broader issues in historical biogeography, such as the predictive power of biogeographic hypotheses, the vicariant/ dispersal duality, the significance of widely distributed taxa, and the need for temporal dimension in biogeographic patterns. A biogeografia dos peixes amazônicos (2.500 espécies de diferentes linhagens) é complexa e até agora foi abordada apenas parcialmente. Aqui abordamos o problema com base no maior banco de dados já feito sobre a distribuição geográfica e as relações filogenéticas dos peixes amazônicos, incluindo todas as informações disponíveis. A distribuição de 4.095 espécies (tanto amazônicas como de grupos-externos) e 84 hipóteses filogenéticas (que incluíam 549 nós filogeneticamente informativos) foram compiladas e qualificadas em 46 áreas (29 amazônicas e 17 não-amazônicas). O banco de dados foi analisado a partir das metodologias PAE, CADE, BPA e BPA0, resultando em topologias amplamente congruentes e indicando que o sinal biogeográfico é detectável em múltiplas dimensões, desde a simples distribuição de peixes até em congruência cladística. A concordância topológica é especialmente pronunciada em componentes mais profundos, como as bacias Trans-Andina, Cis-Andina, Amazonas Ocidental e Orinoco. Os resultados demonstram que todos os principais afluentes amazônicos, bem como a própria bacia amazônica, não são monofiléticos e constituem conjuntos híbridos formados a partir de parcelas bióticas heterogêneas. As drenagens amazônicas não devem ser consideradas a priori como áreas historicamente coesas, contrariamente à prática generalizada. Nossa hipótese permite a reavaliação de questões mais amplas na biogeografia histórica, como o poder preditivo de hipóteses biogeográficas, a dualidade vicariante/dispersão, significância de táxons amplamente distribuídos e a n...

Worthington, 1933, but has been treated as a valid species of Clariallabes by Teugels. Acrochordonichthys melanogaster Bleeker, 1854, is designated as type species of Acrochordonichthys Bleeker, 1857, inasmuch as no earlier valid designation has been found. A new genus Pseudobagarius, is proposed for the "pseudobagarius group" of species formerly placed in Akysis. The status of 228 species group names remains unresolved and 31 names based on otoliths ascribed to catfishes are listed but not placed into the checklist. The current emphasis given to catfish taxonomy at present is likely to result in a dramatic increase in the total number of valid taxa as well as major changes in the membership of some of the higher level taxa recognized here.
