Resumo

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 Sao Joao drainage and other small coastal drainages running to the Baia de Guanabara and to the Baa de Sepetiba in Rio de Janeiro State. We also describe a new species of Hisonotus from drainages of the rio Paraiba do Sul, Lagoa Feia, rio Macae, and coastal rivers of Espirito 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. (AU)
