Brazil (NA): Joly and Escalona 2002: 64 (NA); Moore et al. 2018b: 136 (NA). Other: Endrödi 1963: 331 (Bolivia - as Cyclocephala unicolor ), 1966a: 399, 408 (Bolivia - treated as a synonym of C. luridus ), 1985a: 171 (treated as a synonym of C. luridus ); Joly and Escalona 2002: 64 (Argentina, Bolivia, Paraguay); Moore et al. 2018b: 136 (Argentina, Bolivia). Note. Endrödi (1966a: 399 , 408) synonymizes Chalepides unicolor with C. luridus Burmeister 1847 (p. 78) because he considers the male genitalia a “monstrosity.” This position is retained in Endrödi (1985a: 171) and corrected by Joly and Escalona (2002: 64) .
