Morphological and molecular evidence reveals a new species of Characidium from the Ucayali‐Urubamba Piedmont, Peru, and novel molecular clades are proposed within the genus
Journal of Fish Biology, EarlyView.Abstract
A new species of Characidium is described from the Urubamba River basin, within the Ucayali‐Urubamba Piedmont ecoregion, Peru. The new species can be readily distinguished from all congeners, except Characidium cacah, Characidium chicoi, Characidium helmeri, Characidium mirim, Characidium nana, Characidium nupelia, Characidium sterbai ...Leonardo Oliveira‐Silva, Ricardo Britzke, Vanessa Meza‐Vargas, Max H.

Journal of Fish Biology, EarlyView.Abstract
Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...Pedro L. C. Uzeda, Luana J. Sartori, Axel M. Katz, Felipe P. Ottoni, Wilson J. E. M.

Journal of Fish Biology, EarlyView.Abstract
This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae, an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu ...Ana F. V. N. M. Costa, Antonio A. Jardim Jr, Erival G. Prata, Rafael R.

Journal of Fish Biology, EarlyView.Abstract
Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).Danilo P. Lima, Aline. N.

Journal of Fish Biology, EarlyView.Abstract
A new species of Hyphessobrycon is described from a tributary of Rio Jatuarana, lower Rio Aripuanã basin, Rio Madeira basin, Apuí, Amazonas. The new species is part of the Hyphessobrycon agulha lineage, with the typical midlateral narrow black stripe immediately followed dorsally by an iridescent stripe.Tiago C. Faria, Willian M.
