Cyclocephala gravis H. W. Bates 1888: 308 ( Venezuela, Guatemala, Mexico, Nicaragua, Panama)

Distribution. Guyana: Bodkin 1919: 215; Endrödi 1966a: 209; Maes 1994: 11; Moore et al. 2018b: 181. Suriname: Maes 1994: 11; Moore et al. 2018b: 181. French Guiana: Endrödi 1966a: 209; Maes 1994: 11; Duranton 2011: 13 (?); Moore et al. 2018b: 181. Brazil: Endrödi 1966a: 209; Maes 1994: 11; Ratcliffe 2003: 132; Moore et al. 2018b: 181. Venezuela: H. W. Bates 1888: 308; Arrow 1937b: 11; Blackwelder 1944: 251; Endrödi 1966a: 209; Maes 1994: 11; Moore et al. 2018b: 181. Other: H. W. Bates 1888: 308 (Guatemala, Mexico, Nicaragua, Panama); Arrow 1937b: 11 (Mexico); Blackwelder 1944: 251 (Guatemala, Mexico, Nicaragua, Panama); Endrödi 1966a: 209 (Bolivia, Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Panama), 1985a: 88, 125 (Bolivia–Mexico); Maes 1994: 11 (Bolivia, Colombia, Ecuador, Guatemala, Mexico, Nicaragua, Panama); Ratcliffe 2003: 132 (Brazil/Bolivia–Mexico); Ponchel 2011 (not mentioned); Dupuis 2016b (not mentioned); Moore et al. 2018b: 181 (Belize, Bolivia, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay).

Note 1. Endrödi (1964: 457) describes Cyclocephala meinanderi . The species is reduced to an aberration of C. gravis in Endrödi (1967b: 90) , and this is upheld in Endrödi (1985a: 88). Dechambre (1979c: 164) reinstates it as a valid species and explains this decision. Ratcliffe (B. Ratcliffe, pers. comm.) and Moore et al. (2018b: 181) still consider it a form of C. gravis .

Note 2. As far as we know, Cyclocephala gravis is only reported for the research area by Bodkin (1919: 215) who records it for Guyana, by Endrödi (1966a: 209) who records it for Guyana and French Guiana, and by Maes (1994: 11) who appears to have copied a record for Suriname from an unknown source and mentions Guyana and French Guiana based on Endrödi (1966a) (and is in turn quoted by Moore et al. (2018b: 181)). Duranton (2011: 13) notes he saw no definite specimens from French Guiana, and the species is not mentioned in the checklists for French Guiana by Ponchel (2011) and Dupuis (2016b). We have not seen any specimens from Suriname, and because of the absence of any recent records from the research area, we consider its occurrence there in need of confirmation.
