Abstract:
Our analyses showed that the type series of
Hisonotus notatus , type species of the genus, is mixed, composed by two different species. Based on that, we redescribe
H. notatus with the designation of a lectotype, restricting the species to rio São João drainage and other small coastal drainages running to the BaÃ*a de Guanabara and to the BaÃ*a de Sepetiba in Rio de Janeiro State. We also describe a new species of
Hisonotus from drainages of the rio ParaÃ*ba do Sul, Lagoa Feia, rio Macaé, and coastal rivers of EspÃ*rito Santo State, from rio Itabapoana to rio Doce basin. These two species are sister-taxa and can be distinguished by the number of plates in the mid-dorsal series.
