Silva, G.S.C., Rocha, M.S., Melo, B.F., Reia, L., Roxo, F.F., Sabaj, M.H., & C. Oliveira. (2024). Phylogenomics of the catfish family Pimelodidae with focus on the genus Pimelodus support the recognition of Sorubiminae and Pimelodinae (Teleostei, Siluriformes). Zoologica Scripta, 00, 1–14.

ABSTRACT
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 relationships have remained unclear and have received limited support from various phylogenetic analyses. We provide a new genomic dataset comprising 55 species representing 25 genera of Pimelodidae and related siluriform families Aspredinidae, Auchenipteridae, Cetopsidae, Doradidae, Diplomystidae, Heptapteridae, Loricariidae, and Pseudopimelodidae. Our phylogenetic analyses support the monophyly of Pimelodidae, as well as the existence of four major lineages: the clade, the  +  clade, and two major subclades herein classified as Sorubiminae and Pimelodinae. Our topology resolves sister to differing from previous phylogenies. In Sorubiminae, is sister to two large clades: one with , , and , and the other with , , , , and . In Pimelodinae, we found the clade, the calophysines, and the clade with , , and closer to the group. , , , and are included within the group. The group contains four main components: (1) , (2) the trans-Andean ; (3) clade with species from the Brazilian Shield in southeastern Brazil; and (4) clade composed by species from the Amazon, Orinoco, Paraná-Paraguay, Parnaíba, São Francisco and coastal drainages of the Guiana Shield. The P. maculatus clade is composed by phenotypically diverse species, and the P. blochii clade houses species morphologically similar that appear nested within the widely distributed P. blochii.
