Canthon (Canthon) virens (Mannerheim, 1829)

Ateuchus virens Mannerheim 1829: 36

Note 1. Five presently recognized subspecies of Canthon (Canthon) virens have been described, three of which (may) occur in the research area. The other two are C. (C.) virens paraguayanus Balthasar, 1939 (recorded from Brazil, Paraguay) and C. (C.) virens virens (Mannerheim, 1829) (recorded from Brazil).

Note 2. There has been much confusion regarding the status of Canthon virens, its various subspecies and the synonym C. conformis .

(Canthon) chalybaeum). Venezuela: A. Schmidt 1922a: 74 (as C. conformis); Blackwelder 1944: 198 (as C. conforme); Vulcano and Pereira 1964: 608 (as C. conformis). Other: Blanchard 1846: 163 (Bolivia - as Canthon chalybaeum); Harold 1868a: 86 (Uruguay - as Canthon conformis); A. Schmidt 1922a: 73, 74 (Bolivia - as C. chalybaeus; Bolivia, Paraguay, Peru, [Uruguay] - as C. conformis); Balthasar 1941c: 343 (Peru, Uruguay - as C. conformis); Blackwelder 1944: 198 (Bolivia - as C. chalybaeum; Argentina, Bolivia, Paraguay, Peru, Uruguay - as C. conforme); Vulcano and Pereira 1964: 606, 608 (Bolivia - as C. chalybaeus; Argentina, Paraguay, Peru, Uruguay - as C. conformis).

Note. Canthon virens chalybaeus is only mentioned for the Guianas in A. Schmidt (1922a: 74) and Blackwelder (1944: 198) (as C. conformis from French Guiana). Because this is a single record of considerable age, and because there is already another subspecies known from French Guiana, we consider this record doubtful and in need of confirmation.
