Resumen:
A new monotypic genus of Naupactini (Coleoptera: Curculionidae), Obrieniolus del Río is described
based on the new species Obrieniolus robustus del Río, endemic to Peru. This genus is easily recognized
by the black, denuded and shiny integument, with imbricate microsculpture and the rounded body, with
short, cordiform and moderately convex elytra. According to a cladistic analysis based on 69 continuous
and discrete morphological characters, the new genus is the sister taxon of a group formed by AmitrusObrieniolus del Río is described
