A new species of freshwater anomuran, Aegla renana n. sp. (Decapoda: Aeglidae), is described from the Caí River sub-basin, a tributary of the Jacuí/Guaíba system, from the northwest region of the state of Rio Grande do Sul, Brazil. It can be distinguished from its congeners based on both morphological and molecular evidence. Morphologically, the new species partly resembles Aegla ligulata because of its ligulate rostrum; however, A. renana has an inflated left propodus of the cheliped, similar to that of A. manuinflata. Based on the phylogenetic analysis of DNA sequence data, A. renana has a sister relationship with A. itacolomiensis and both are clustered with the A. longirostri-A. inermis clade. New distribution records of A. franciscana, A. longirostri and A. inermis, which occur in the same hydrographic basin, are provided.
