Abstract
ARAYA, Patricia Raquel; FLORES, Silvia Alicia; SERRANO, Marcelo Javier and BARBOZA, Adriana Griselda. First record of Psalidodon dissensus (Lucena & Thofehrn 2013) (Characiformes, Characidae) in tributaries of Uruguay River basin, Misiones, Argentina. Actu Biol [online]. 2021, vol.43, n.114, e4. Epub Jan 21, 2022. ISSN 0304-3584. https://doi.org/10.17533/udea.acbi/v43n114a04.
The first record of Psalidodon dissensus in water courses of the province of Misiones, from specimens from the Yabotí stream, a tributary of the Uruguay River, immersed in the Yabotí Biosphere Reserve. Psalidodon, revalidated from the synonymy of the genus Astyanax, includes 21 new combinations for Argentina of which seven are present in the river systems of Misiones. The ichthyofauna of the province, belonging to the Parano-Platense Province, is characterized by the high diversity and endemism that make it a territory of formidable biological value and in urgent need of conservation.
Keywords : Diversity; ichthyofauna; Yabotí Biosphere Reserve.
