A new species of Naupactini (Curculionidae: Entiminae) endemic to Brazil, Espírito Santo and Minas Gerais states, is herein described. It resembles the monotypic genus Hadropus Schoenherr in its general appearance, particularly in the shape of the elytra, and the color of the vestiture, but the results of a cladistics analysis herein conducted suggest that it belongs to the genus Stenocyphus Marshall. This genus ranges in São Paulo, Rio de Janeiro and Espírito Santo, mainly in the Atlantic forest of Brazil, and includes three other species. Stenocyphus costae sp. nov., distinguishes from the remaining species of Stenocyphus by the green iridescent scaly vestiture, having long stiff setae on the two pairs of elytral tubercles; the more slender rostrum; the shorter antennae; the convex disc of the pronotum; and the shorter and broader elytra. This paper includes a cladogram of the Naupactini genera showing the phylogenetic position of the new species, its complete description, photographs of male and female habitus, line drawings of genitalia of both sexes, and a key of the Stenocyphus species.
