Phylogenomics of the catfish family Pimelodidae with focus on the genus Pimelodus support the recognition of Sorubiminae and Pimelodinae (Teleostei, Siluriformes)
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 Steindachneridion clade, the Leiarius + Phractocephalus clade, and two major subclades herein classified as Sorubiminae and Pimelodinae. Our topology resolves Phractocephalus sister to Leiarius differing from previous phylogenies. In Sorubiminae, Zungaro is sister to two large clades: one with Sorubim, Sorubimichthys, and Pseudoplatystoma, and the other with Hemisorubim, Platysilurus, Platystomatichthys, Brachyplatystoma, and Hypophthalmus. In Pimelodinae, we found the Pimelodus ornatus clade, the calophysines, and the clade with Exallodontus, Propimelodus, and Pimelodus altissimus closer to the Pimelodus group. Parapimelodus, Duopalatinus, Iheringichthys, and Bergiaria are included within the Pimelodus group. The Pimelodus group contains four main components: (1) Duopalatinus peruanus, (2) the trans‐Andean Pimelodus grosskopfii; (3) Pimelodus maculatus clade with species from the Brazilian Shield in southeastern Brazil; and (4) Pimelodus blochii 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.
期刊介绍:
Zoologica Scripta publishes papers in animal systematics and phylogeny, i.e. studies of evolutionary relationships among taxa, and the origin and evolution of biological diversity. Papers can also deal with ecological interactions and geographic distributions (phylogeography) if the results are placed in a wider phylogenetic/systematic/evolutionary context. Zoologica Scripta encourages papers on the development of methods for all aspects of phylogenetic inference and biological nomenclature/classification.
Articles published in Zoologica Scripta must be original and present either theoretical or empirical studies of interest to a broad audience in systematics and phylogeny. Purely taxonomic papers, like species descriptions without being placed in a wider systematic/phylogenetic context, will not be considered.
