§ Gymnetis undata ( Olivier, 1789)

Cetonia undata Olivier 1789: 84 ( French Guiana)

Distribution. Suriname: Ratcliffe 2018: 223. French Guiana: Olivier 1789: 84 (as Cetonia undata ); Ratcliffe 2018: 223. Brazil: Schenkling 1921: 99; Blackwelder 1944: 263 (as Paragymnetis chalcipes undata ). Other: Schenkling 1921: 99 ( Argentina, Haiti); Blackwelder 1944: 263 ( Argentina, Hispaniola - as Paragymnetis chalcipes undata ); Ratcliffe 2018: 223 ( Dominican Republic, Haiti, Puerto Rico).

Note 1. According to Ratcliffe (2018: 223), only singletons of Gymnetis undata are known from both Suriname and French Guiana. Given that this species is otherwise only found on several of the West Indian islands over 1600 km away, we consider it likely that the specimens from Suriname and French Guiana are either mislabeled or were accidentally transported from the islands on which they naturally occur. We consider this species neither naturally occurring in the research area nor having an established adventive population there.

Note 2. The records of Gymnetis undata for Brazil and Argentina in Schenkling (1921: 99) and Blackwelder (1944: 263) may, according to Ratcliffe (2018), be based on an error in Gory and Percheron (1833: 356 (not 556)) and confusion with the rather similar Gymnetis chalcipes Gory and Percheron (1833: 71 , 354), which occurs only in southern and eastern South America.
