Cyclocephala rufonigra Demay, 1838

Cyclocephala rufo-nigra Demay 1838: 23 ( French Guiana)

Distribution. Guyana: Endrödi 1985a: 148; Moore et al. 2018b: 242. French Guiana: Demay 1838: 23. “Guianas”: Arrow 1937b: 15; Blackwelder 1944: 252. Other: Endrödi 1966a: 298 (none).

Note 1. Demay presented to a congress in Metz [ France] a leaflet, accompanied by figures, containing allegedly the descriptions of thirteen beetle species found in French Guiana. He sent an extract of this leaflet to the Revue Zoologique, which was then published ( Demay 1838: 23). This publication contains just eleven non-illustrated descriptions, one of which is the only known record of Cyclocephala rufonigra . The type locality is erroneously altered to “ Guyana ” in Endrödi (1985a: 148) and Moore et al. (2018b: 242).

Note 2. Burmeister (1847: 521) suspects Cyclocephala rufonigra may be synonymous with C. dorsalis (which is now a synonym of C. dispar ). The present location of the type material is unknown and this species thus remains a species inquirendum.
