On UV/HPL.); NZCS. Note. Ratcliffe (2008: 226) describes Cyclocephala chera based on 10 female specimens from Guyana . In this description, Ratcliffe compares C. chera with C. complanata Burmeister, 1847 (p. 48), C. conspicua Sharp, 1877 (p. 135) and C. gregaria Heyne and Taschenberg, 1908 (p. 91), but not with C. undata ( Olivier, 1789 ) (p. 80). We have collected a number of specimens in Suriname , including several males, which were identified as C. chera by Ratcliffe. After viewing photos of these specimens, Ponchel (Y. Ponchel, pers. comm. 2015) considers them synonymous with C. undata , which he says has a bicolored and a unicolored morph. Now that we have found male specimens of C. chera it seems prudent to compare both sexes of C. chera with those of both color morphs of C. undata .
