The genus Rhopalessa is revised and divided into two groups: the clavicornis-group with R. clavicornis (Bates, 1873), R. demissa (Melzer, 1934), R. hirticollis (Zajciw, 1958), R. moraguesi (Tavakilian & Peñaherrera-Leiva, 2003), R. pilosicollis (Zajciw, 1966) and R. subandina sp. nov.; and the rubroscutellaris-group with R. durantoni (Peñaherrera-Leiva & Tavakilian, 2004) and R. rubroscutellaris (Tippmann, 1960). Two species were synonymyzed with R. clavicornis: Ommata (Rhopalessa) nigrotarsis Fisher, 1937 and Ommata (Rhopalessa) nigricollis Zajciw, 1969.
