Pimelodus microstoma Steindachner, 1877, a valid species of pimelodid catfish (Siluriformes: Pimelodidae) from the upper rio Paraná drainage

Abstract

Pimelodus microstoma, which has been treated as a junior synonym of P. fur, is resurrected and its type locality restricted to Irisanga (=Orissanga), São Paulo State, in the upper rio Paraná. An identification key is provided for Pimelodus species from the upper portions of the Paraná drainage.Pimelodus microstoma, espécie que tem sido tratada como sinônimo júnior de P. fur, é revalidada e sua localidade-tipo restringida para Irisanga (=Orissanga), Estado de São Paulo, alto rio Paraná. Uma chave de identificação das espécies de Pimelodus da porção superior do rio Paraná é fornecida.

Pimelodus pintado (Siluriformes: Pimelodidae), a new species of catfish from affluent rivers of Laguna Merín, Uruguay, South America

“…Some of these are, however, sufficiently divergent to be recognized as distinct species. In fact, several other weakly to strongly maculated but otherwise distinct species of Pimelodus occur in the Paraná or São Francisco rivers including some recently described: P. absconditus Azpelicueta, 1995, P. britskii Gravello andShibatta, 2007, P. fur (Lütken 1874), P. heraldoi Azpelicueta, 2001, P. microstoma Steindachner, 1877 (see Ribeiro and Lucena, 2007), P. mysteriosus Azpelicueta, 1998, P. ortmanni Haseman, 1911, P. paranaensis Britski and Langeani, 1988, P. platicirris Borodin, 1927 pohli Ribeiro and Lucena, 2006. In this paper we describe a new and strikinglyspotted species of Pimelodus from the Cebollatí, Tacuarí and Yaguarón rivers in Uruguay that empty into Laguna Merín (Fig. 1).…”

Isolation and characterization of microsatellite loci in Pimelodus microstoma (Siluriformes: Pimelodidae)

“…This fish presents a deep and robust body; relatively long adipose fin; prominent upper jaw; small mouth with short lower jawbone; and a uniform gray color pattern with a few dark spots (sometimes light or absent) in the anterolateral region (Ribeiro & Lucena, 2007).…”

Taxonomy of Pimelodus brevis Marini, Nichols & La Monte, 1933 (Siluriformes: Pimelodidae), an uncertain species from the rio Paraná basin

“…comm.). Nevertheless some authors have considered it as valid (e.g., Ringuelet, 1940;Pozzi, 1945;Ringuelet et al, 1967;Lundberg & Littmann, 2003;Ferraris Jr., 2007;Ribeiro & Lucena, 2007;Ribeiro et al, 2011), in some cases, solely based on the original description and its single illustration of the holotype. A taxonomic analysis comprising material from the rio Paraná basin provided additional specimens that made it possible to demonstrate the identity of Pimelodus brevis.…”
