“…These 58 sampling sites are distributed among streams from first to third order in 18 municipalities in Mato Grosso do Sul, Brazil (Figure 1). Taxonomic and distribution data from additional studies were also added to the final species list (Sabino & Trajano 1997, Willink et al 2000, Ribeiro et al 2007, Terra & Sabino 2007, Zawadzki et al 2014, Shibatta 2016.…”

The objective of this study was to provide a comprehensive list of the fish fauna of headwater streams of the Miranda River in the Upper Paraguay River Basin. Our primary data set was constructed from sampling of fish using a rectangular sieve, trawl, and gill nets from 2004 to 2015. Our secondary data were derived from published reports conducted in the Miranda River Basin, in addition to taxonomic and distribution data from other studies conducted in the basin. All data were compiled, which in the end encompassed a period from 1999 to 2015. The datasets yielded a total of 143 species, 104 from the primary data (72.7%) and 39 from the secondary data (27.3%). Species were distributed among seven orders and 30 families were found in the Miranda River Basin. Characiformes and Siluriformes were the predominant orders, and the families Characidae and Loricariidae had the greatest number of species. Our results indicate a greater number of species compared to other studies of the Upper Paraguay Basin headwaters, likely due to the longer time frame covered by our primary and secondary datasets.

“…Pseudopimelodidae is currently divided into seven genera: Batrochoglanis Gill, 1858; Cephalosilurus Haseman, 1911; Cruciglanis Ortega‐Lara & Lehmann, 2006; Lophiosilurus Steindachner, 1889; Microglanis Eigenmann, 1912; Pseudopimelodus Bleeker, 1858, and Rhyacoglanis Shibatta & Vari, 2017. The systematic understanding of the family was recently improved with the descriptions of two genera (Ortega‐Lara & Lehmann, 2006; Shibatta & Vari, 2017), and multiple species, especially in Batrochoglanis (Shibatta, 2019; Shibatta & Pavanelli, 2005), Microglanis (e.g., Sarmento‐Soares et al, 2006; Ruiz, 2016; Shibatta, 2016; Terán et al, 2016; Souza‐Shibatta et al, 2018), and Pseudopimelodus (Restrepo‐Gómez et al, 2020). Sixteen out of the 53 valid species of Pseudopimelodidae were described in the last 10 years (Fricke et al, 2021).…”

Neotropical catfishes of the family Pseudopimelodidae comprise 53 species allocated to seven genera widely distributed in South America from northwestern Colombia and Venezuela to Argentina and Uruguay. Intergeneric relationships based on morphology‐based phylogenies are conflicting, and the interspecific relationships remain incipient. We conducted the first molecular phylogeny of the family by analyzing sequence data from ultraconserved elements (UCEs) of the genome for 33 specimens of Pseudopimelodidae and 19 related taxa. Phylogenetic relationships were accessed by concatenated matrices using Bayesian inference and, maximum likelihood, and the coalescent approach by a species tree analysis. The phylogeny with 868 UCE loci and 906,689 bp strongly support the monophyly of Pseudopimelodidae, and the arrangement of two major subclades herein classified as subfamilies Pseudopimelodinae and the newly proposed Batrochoglaninae. Pseudopimelodinae is composed by Cruciglanis sister to Pseudopimelodus and Rhyacoglanis, whereas the new subfamily Batrochoglaninae is composed by Cephalosilurus and Lophiosilurus as sister to Batrochoglanis and Microglanis. Pseudopimelodinae is supported by five morphological synapomorphies and Batrochoglaninae supported by three such synapomorphies. The results of this study will surely guide future research aiming to delimit and describe species within the monophyletic groups.

“…The order Siluriformes is a highly diverse group encompassing at least 3975 valid species (Fricke, Eschmeyer & Fong, 2020) and a growing number of new species are being described (Shibatta, 2016;Ruiz, 2016;Shibatta & Vari, 2017;Shibatta, 2019;Tobes et al, 2020). Within this order, Pseudopimelodidae (Bumblebee catfishes) is a small monophyletic family of Neotropical catfishes, broadly distributed across different river basins in South America, from the Atrato River in Colombia to the Río de la Plata in Argentina (Ferraris Jr, the names P. schultzi and P. bufonius, this study integrated molecular and morphological analyses, including osteology and external morphology, to address the taxonomic status of Pseudopimelodus species inhabiting the Magdalena-Cauca River Basin.…”

The family Pseudopimelodidae is widely distributed in South America and includes 51 described species organized in seven genera. Only two of four species of the genus Pseudopimelodus have been recorded for the trans-Andean basins of Colombia, Pseudopimelodus bufonius and P. schultzi, whose similarity in external morphology make their identification difficult. We performed a phylogenetic analysis using a fragment of the Cytochrome C Oxidase subunit 1 gene (COI), and analyzed osteological and traditional morphometric characters to study Pseudopimelodus from the Colombian trans-Andean region. Results provided strong support for two clades phylogenetically related to Pseudopimelodus, that showed clear-cut molecular, osteological, and morphometric differences from previously described bumblebee catfishes. Based on these results, we describe two Pseudopimelodus species from the Magdalena-Cauca River Basin: P. magnus sp. nov. with 43–44 vertebrae, dorsal-fin spine with serrations on its anterior margin; lateral margin of transverse process of the fourth vertebra of the Weberian complex forming an acute angle in ventral view and P. atricaudus sp. nov. with 39 vertebrae, dorsal-fin spine smooth on its anterior margin and a dark, vertical band covering 3/4 of the caudal fin with base of rays and tip of caudal-fin lobes hyaline.
