Schmidt, 1922 Canthon coloratus A. Schmidt 1922a: 86 ( Brazil - LECTOTYPE ) Distribution. French Guiana : A. Schmidt 1922a: 70 , 73, 86; Balthasar 1941c: 344 ; Blackwelder 1944: 198 (as C. coloratum ); Pereira and Martínez 1956b: 159 (as Geocanthon coloratus ). “Guianas”: Vulcano and Pereira 1964: 669 (as Geocanthon coloratus ). Brazil : A. Schmidt 1922a: 70 , 73, 86; Balthasar 1941c: 344 ; Blackwelder 1944: 198 (as C. coloratum ); Pereira and Martínez 1956b: 159 (as Geocanthon coloratus ); Vulcano and Pereira 1964: 669 (as Geocanthon coloratus ); Vaz-de-Mello 2000: 191 (as C. ( Glaphyrocanthon ) coloratum ); Vaz-de-Mello and Cupello 2018b: 58 (designation LECTOTYPE Canthon coloratus ). Other: A. Schmidt 1922a: 70 , 73, 86 ( Peru ); Balthasar 1939e: 217 ( Peru ), 1941c: 344 ( Peru ); Blackwelder 1944: 198 ( Peru - as C. coloratum ); Pereira and Martínez 1956b: 159 ( Peru - as Geocanthon coloratus ); Vulcano and Pereira 1964: 669 ( Peru - as Geocanthon coloratus ). 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.
