Cyclocephala signaticollis Burmeister 1847: 63 ( Argentina - LECTOTYPE)

Distribution. French Guiana: Endrödi 1966a: 308; Duranton 2011: 15 (?); Moore et al. 2018b: 247. Brazil: Endrödi 1966a: 308; Moore et al. 2018b: 247. Venezuela: Endrödi 1966a: 308, 1985a: 98, 140; Moore et al. 2018b: 247. Other: Burmeister 1847: 63 (Argentina); Arrow 1937b: 16 (Argentina); Blackwelder 1944: 252 (Argentina); Endrödi 1966a: 308 (Argentina - designation NEOTYPE Cyclocephala signaticollis , Bolivia, Colombia, Mexico, Uruguay, Australia), 1985a: 98, 140 (Venezuela–Argentina, Mexico, Australia); Dechambre 1991: 124 (Argentina - designation LECTOTYPE Cyclocephala signaticollis ); Ponchel 2011 (not mentioned); Dupuis 2016b (not mentioned); Moore et al. 2018b: 247 (Argentina, Bolivia, Colombia, Uruguay, Australia).

Note 1. The neotype of Cyclocephala signaticollis designated in Endrödi (1966a: 308) was rendered invalid when type material from Burmeister was recovered and a lectotype was designated in Dechambre (1991: 124).

Note 2. Endrödi (1966a: 308) records Cyclocephala signaticollis for French Guiana, but this record is not repeated in later publications except for Moore et al. (2018b: 247). Duranton (2011: 13) apparently saw no definite specimens from French Guiana, and the species is not mentioned by Ponchel (2011) and Dupuis (2016b). We are unaware of any other records from the research area and have not seen any specimens from the Guianas. We assume this species does not occur in the research area and treat it as such.

Note 3. Endrödi (1966a: 308) records Cyclocephala signaticollis for Mexico, and this record is repeated in Endrödi (1985a: 98, 140). However, according to Ratcliffe et al. (2013: 597) this species only occurs in South America and Australia (where it was introduced), which means that the specimen on which the record was based was either mislabeled or misidentified.
