Redescriptions of two little-known pimelodid catfishes from the São Francisco River basin, Brazil: Duopalatinus emarginatus and Bagropsis reinhardti (Teleostei: Siluriformes) Open
The São Francisco River basin in eastern Brazil harbors a highly endemic ichthyofauna, including the poorly known pimelodid catfishes Duopalatinus emarginatus and Bagropsis reinhardti. Despite being described in the 19th century, these spe…

Phylogenomics of the catfish family Pimelodidae with focus on the genus <i>Pimelodus</i> support the recognition of Sorubiminae and Pimelodinae (Teleostei, Siluriformes) Open
Pimelodidae is a family of large‐sized catfishes consisting of 116 valid species divided into 30 genera distributed in the Neotropical region. Despite recent advancements in understanding the pimelodid phylogeny, several internal relations…

New species of Rhyacoglanis (Siluriformes: Pseudopimelodidae) from rio Tocantins basin, northern Brazil Open
A new species of Rhyacoglanis is described from the rapids of Jatobal, Pará State, Brazil. This species differs from the congeners by fusing hypurals 3, 4, and 5 (vs. hypural 5 free). It also differs from the other species, except for Rhya…
