Note 1. Endrödi (1966a: 294, 1985a: 147) mentions not seeing any specimens of Cyclocephala quercina , but according to Endrödi (1966a: 268, 1985a: 98, 139) he did examine specimens of C. obesa .

Note 2. According to Ratcliffe (2003: 225), the records in Endrödi (1966a: 268, 1985a: 98, 139) of Cyclocephala obesa (now a synonym of C. quercina ) from Costa Rica, Honduras and the U.S.A. are incorrect, as this is a South American species.

Note 3. Despite the synonymization of Cyclocephala obesa with C. quercina in Dechambre and Duranton (2005: 67) , Duranton (2011: 14) lists both names again as separate species. The reason for this is unknown to us.
