Two species of Gyponinae from Peru and Central America with similar external characteristics were studied. They are placed in a new genus, Tenuacia, and one new subgenus, Rubacea. The new genus Tenuacia, species T. macera n. sp., subgenus Rubacea and species T. (R). rubera n. sp. Gyponinae are described. In both species the head is broadly rounded and strongly produced with the eyes partly surrounded by the crown. The aedeagus in Tenuacia bears parameres but does not in Rubacea.
