Phylogenetic analysis demonstrates that Bergidea, with two species, is a paraphyletic South American mainland genus (Chile, Argentina) from which evolved a holophyletic group of two genera on the Juan Fernandez Islands, Micrymenus and Rugomenus, each with two species. Bergidea atrata and Micrymenus brevalatus are new species and Rugomenus is a new genus (Rhyparochrominae, Ozophorini).
