§ Canthidium (Neocanthidium) gigas Balthasar, 1939

Canthidium gigas Balthasar 1939f: 127 (French Guiana)

Distribution. French Guiana: Balthasar 1939f: 127; Martínez 1947b: 111. “Guianas”: Martínez and Halffter 1986a: 27 (as C. (Canthidium) gigas); Cupello 2018: 469. Brazil: Carvalho de Santana et al. 2019: 15. Other: Blackwelder 1944 (not mentioned).

Note. Balthasar (1939f: 127) describes Canthidium gigas from French Guiana, and this is also the distribution given in Martínez (1947b: 111). Martínez and Halffter (1986a: 27) and Cupello (2018: 469) only mention “Guianas.” In their treatment of this species, Carvalho de Santana et al. (2019: 11) mention that it is actually restricted to parts of southern Brazil. The specimen used by Balthasar (1939f) to describe this species was likely mislabeled.
