Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

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 ...

Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

Zoologica Scripta, EarlyView.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...
