Phylogenetic relationships of the suckermouth armoured catfishes (Loricariidae) with emphasis on the Hypostominae and the Ancistrinae
A phylogenetic analysis of nearly all genera of the Hypostominae and the Ancistrinae is provided based on osteology, external anatomy, and digestive tract anatomy. The results suggest that the…

The genus Peckoltia with the description of two new species and a reanalysis of the phylogeny of the genera of the Hypostominae (Siluriformes: Loricariidae)
TLDR
A revised morphological phylogeny demonstrates the lack of support for Peckoltia and Hemiancistrus as monophyletic, and phenetic definitions are provided for the two genera.

Redescription of Pterygoplichthys punctatus and description of a new species of Pterygoplichthys (Siluriformes: Loricariidae)
Pterygoplichthys punctatus and P. weberi, new species, are unique among hypostomines in having a medially divided buccal papilla. The two species can be separated from one another by color (small…

Genome-wide interrogation advances resolution of recalcitrant groups in the tree of life
TLDR
GGI is shown to be efficacy in resolving the controversial relationships within the largest freshwater fish radiation (Otophysi) based on newly generated DNA sequences for 1,051 loci from 225 species and supports the notion that ctenophores are the earliest-branching animal lineage, and adds insight into relationships within clades of yeasts, birds and mammals.

Phylogenetic classification of extant genera of fishes of the order Cypriniformes (Teleostei: Ostariophysi).
TLDR
An updated compilation of the membership of genera to suprageneric taxa based on the latest phylogenetic classifications is provided and a new taxon is proposed: subfamily Esominae within Danionidae, for the genus Esomus.

Delturinae, a new loricariid catfish subfamily (Teleostei, Siluriformes), with revisions of Delturus and Hemipsilichthys
TLDR
The geographical distribution of Delturinae, exclusively on the south-eastern Brazilian Shield, indicates that south-Eastern Brazil acts as either a refugium for basal loricariid taxa or a point of origin for the Loricariidae.

The channel catfish genome sequence provides insights into the evolution of scale formation in teleosts
TLDR
A high-quality reference genome sequence of channel catfish is reported, providing evidence that lack of secretory calcium-binding phosphoproteins accounts for the evolutionary loss of scales in catfish and demonstrates the power of comparative subtraction of candidate genes for traits of structural significance.
