Abstract
The Neotropical genus Benthana Budde-Lund, 1908 includes 22 species, three of them allocated to the subgenus Benth-anoscia Lemos de Castro, 1958. A new species is described from the state of Parana, Brazil. This new species is distinguished from its congeners by having 8+2 aesthetascs on the antennula, the first article of the antennal flagellum unpigmented, the proximal inner tooth of the inner pectinate set of the maxillula with 7 denticles, and the pleopod 1 exo-pod with a dentiform protmsion witha concave appearance.
