Distribution. Suriname: Uyttenboogaart 1902: 116; Moore et al. 2018b: 242; MHCN; NZCS. French Guiana: Endrödi 1966a: 299 (as C. rustica municipalis ; as C. rustica rustica (?)), 1985a: 35, 116 (Guyana [> Fr. Guiana] - as C. rustica municipalis ); Duranton 2011: 15; Ponchel 2011: 60; Dupuis 2016b: 109; Moore et al. 2018b: 242. “Guianas”: Höhne 1923b: 365; Arrow 1937b: 15; Blackwelder 1944: 252. Brazil (NA): Höhne 1923b: 365 (as C. rustica municipalis ); Endrödi 1966a: 299 (as C. rustica municipalis ) (NA); Endrödi 1985a: 35, 116 (as C. rustica municipalis ); Moore et al. 2018b: 242. Venezuela: Höhne 1923b: 365 (as C. rustica municipalis ); Endrödi 1966a: 299 (designation LECTOTYPE Cyclocephala rustica municipalis ); Endrödi 1985a: 35, 116 (as C. rustica municipalis ); Moore et al. 2018b: 242. Other: Olivier 1789: 27 (Guadeloupe); Höhne 1923b: 365 (Colombia, Mexico - as C. rustica municipalis ; Trinidad and Tobago - as C. rustica rustica ); Blackwelder 1944: 252 (Guadeloupe); Endrödi 1966a: 299 (Colombia, Mexico, Peru - as C. rustica municipalis ; Guadeloupe, Trinidad and Tobago - designation NEOTYPE Melolontha rustica ), 1985a: 35, 116 (Colombia, Mexico, Peru - as C. rustica municipalis ; Guadeloupe, Trinidad and Tobago - as C. rustica rustica ); Moore et al. 2018b: 242 (Colombia, Peru, Trinidad and Tobago).

Note 1. Moore et al. (2018b: 107) conclude that the neotype of Melolontha rustica designated in Endrödi (1966a: 299) is invalid because it violates several demands of Article 75 of the ICZN (1964: 81).

Note 2. Olivier (1789: 27) describes Cyclocephala rustica from Guadeloupe, and this record is copied in Blackwelder (1944: 252) and Endrödi (1966a: 299, 1985a: 35, 116). However, Ratcliffe and Cave (2015: 291), addressing just Endrödi (1966a), claim this record is incorrect, as C. rustica is a South American species. Olivier’s type specimen may be mislabeled.

Note 3. In Endrödi (1966a: 299), both Cyclocephala rustica rustica and C. rustica municipalis are reported from “Guayana: Cayenne,” which is French Guiana. In Endrödi (1985a: 35) Guyana, but not French Guiana, is mentioned for C. rustica municipalis (with C. rustica rustica only being mentioned for the Antilles). As all more specific locations were omitted in the 1985 publication, we assume the remaining “Guayana” erroneously became Guyana. We are unaware of actual records of this species from Guyana.
