Note. Despite many collecting efforts in Suriname and French Guiana in recent years, we have found no specimens or recent records of Canthon coloratus for the research area. All records for French Guiana in the literature ( Balthasar 1941c: 344; Blackwelder 1944: 198; Pereira and Martínez 1956b: 159; Vulcano and Pereira 1964: 669) can be traced back to the original description by A. Schmidt (1922a: 86), which may have been based on a mislabeled specimen. We consider the occurrence of this species in the research area doubtful and in need of confirmation.
