The genus Roleta McDermott is revised. This was a monobasic genus and its type species, R. coracina McDermott, is found to be a junior synonym of Calyptocephalus notaticollis Pic. Four other species of Calyptocephalus, C. austerus Olivier, C. hilaris Olivier and C. inornatus Olivier and C. cincticollis Pic, are transferred to Roleta; austerus and inornatus received mandatory changes to their specific epithets in the new combinations. A key to the species is provided. The systematic position of the genus is discussed.
