Journal of Zoological Systematics and Evolutionary Research.

Abstract
Lacépède, 1803, is a species-rich and widespread fish genus from the Neotropical region, but its evolutionary history and systematics remain largely unclear. In addition, species from regions with high levels of species richness and endemism such as the Northeastern Mata Atlântica (NMA) and São Francisco (SF) hydrographic freshwater ecoregions are underrepresented in phylogenetic studies so far. In this study, we performed a broad sampling of Hypostomus in NMA and SF to investigate the interspecific boundaries and phylogenetic relationships using a multilocus approach based on one mitochondrial and three nuclear markers. Seven genetic groups were found for both ecoregions, in addition to one lineage exclusive to the SF represented by populations of the species . Moreover, multilocus analyses validated 16 formally described species and two new lineages for the NMA and SF ecoregions, as well as putative cases of species complexes. In general, lineages with independent evolutionary histories were revealed within the same ecoregion alongside genetically related groups between NMA, SF, and other ecoregions. These data reinforce the intricate scenario of this group of Neotropical fish and are useful to outline further phylogeographic studies in Hypostomus.

Delving into at the moment, so a copy of this would be useful/interesting if available, please?

It'll have to come from someone else. I have an embargo period to wait before my univ gains access.

Sorry, Eric
