Note. Two presently recognized subspecies of Canthon (Francmonrosia) rutilans have been described, one of which may occur in the research area. The other one is C. (F.) rutilans cyanescens Harold, 1868 (recorded from Brazil, Argentina, Mexico, Paraguay).

Subspecies Canthon (Francmonrosia) rutilans rutilans Laporte, 1840

Canthon rutilans Laporte 1840: 69 ( Brazil - LECTOTYPE)

Distribution. French Guiana: A. Schmidt 1922a: 80; Blackwelder 1944: 201. Brazil: Laporte 1840: 69; Gillet 1911b: 33 (as C. rutilans [s. l.]); A. Schmidt 1922a: 80; Balthasar 1939e: 206 (as C. rutilans [s. l.]); Blackwelder 1944: 201; Vulcano and Pereira 1964: 601 (as Francmonrosia rutilans [s. l.]); Vazde-Mello 2000: 191; Vaz-de-Mello and Cupello 2018a: 53 (designation LECTOTYPE Canthon rutilans ). Other: Gillet 1911b: 33 ( Argentina - as C. rutilans [s. l.]); A. Schmidt 1922a: 80 ( Argentina); Balthasar 1939e: 206 ( Argentina - as C. rutilans [s. l.]); Blackwelder 1944: 201 ( Argentina); Vulcano and Pereira 1964: 601 ( Argentina, Paraguay, Uruguay - as Francmonrosia rutilans [s. l.]).

Note. With the exception of a single record from the state of Pará in Brazil, all other records for Canthon rutilans rutilans are much farther south. As such, we regard the old records from French Guiana in A. Schmidt (1922a: 80) and Blackwelder (1944: 201) as dubious. The presence of this species in the research area is in need of confirmation.
