Canthon (Glaphyrocanthon) subcyaneus Erichson, 1848

Canthon subcyaneus Erichson 1848: 563 ( Guyana)

Distribution. Guyana: Erichson 1848: 563; A. Schmidt 1922a: 81; Blackwelder 1944: 202 (as C. subcyaneum ). Suriname: RMNH - NEW COUNTRY RECORD (Suriname, Marowijne, Moengota-poe–Wia Wia. 13-X-1948. D. C. Geijskes.). French Guiana: Gillet 1911b: 34; Balthasar 1939e: 208; Blackwelder 1944: 202 (as C. subcyaneum ); Vulcano and Pereira 1964: 631. Brazil: A. Schmidt 1922a: 81; Blackwelder 1944: 202 (as C. subcyaneum ); Vulcano and Pereira 1964: 631; Vaz-de-Mello 2000: 191 (as C. (Glaphyrocanthon) subcyaneum ). Venezuela: A. Schmidt 1922a: 81; Blackwelder 1944: 202 (as C. subcyaneum ); Vulcano and Pereira 1964: 631. Other: A. Schmidt 1922a: 81 (Colombia); Blackwelder 1944: 202 (Colombia - as C. subcyaneum ); Vulcano and Pereira 1964: 631 (Colombia); Medina et al. 2001: 136 (Colombia?).

Note. Gillet (1911b: 34) and Balthasar (1939e: 208) apparently misread the locality data as given by Erichson (1848: 563) and/or Harold (1868a: 117) and recorded Canthon subcyaneus for Cayenne (presentday French Guiana) instead of British Guiana (present-day Guyana). As Blackwelder (1944: 202) and Vulcano and Pereira (1964: 631) have mostly copied records from other unoriginal authors, their records from French Guiana may be based on the erroneous records of Gillet (1911b) and Balthasar (1939e). We have not seen recent records from French Guiana in the available literature. However, our new country record for Suriname, which comes from the east of this country, indicates that the species may be present in French Guiana after all, but this needs to be confirmed.
