A taxonomically complex catfish group from an underrepresented geographic area: Systematics and species limits in Hypostomus Lacépède, 1803 (Siluriformes, Loricariidae) from Eastern South America
Hypostomus 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 Hypostomusvelhochico. 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.
期刊介绍:
The Journal of Zoological Systematics and Evolutionary Research (JZSER)is a peer-reviewed, international forum for publication of high-quality research on systematic zoology and evolutionary biology. The aim of the journal is to provoke a synthesis of results from morphology, physiology, animal geography, ecology, ethology, evolutionary genetics, population genetics, developmental biology and molecular biology. Besides empirical papers, theoretical contributions and review articles are welcome. Integrative and interdisciplinary contributions are particularly preferred. Purely taxonomic and predominantly cytogenetic manuscripts will not be accepted except in rare cases, and then only at the Editor-in-Chief''s discretion. The same is true for phylogenetic studies based solely on mitochondrial marker sequences without any additional methodological approach. To encourage scientific exchange and discussions, authors are invited to send critical comments on previously published articles. Only papers in English language are accepted.
