§ Canthon (Peltecanthon) sulcatus Laporte, 1840
Canthon sulcatus Laporte 1840: 69 (French Guiana)
= Canthon prasinus Harold 1867b: 78 (Brazil)
Distribution. French Guiana: Laporte 1840: 69; A. Schmidt 1922a: 81; Blackwelder 1944: 202 (as C. sulcatum). Brazil: Harold 1867b: 78 (as C. prasinus); Gillet 1911b: 32, 34 (as C. prasinus; as C. sulcatus); A. Schmidt 1922a: 81; Balthasar 1939e: 203; Blackwelder 1944: 201, 202 (as C. prasinum; as C. sulcatum); Vulcano and Pereira 1964: 574 (as Peltecanthon sulcatus); Halffter and Martínez 1967: 88 (as Peltecanthon sulcatus); Vaz-de-Mello 2000: 191 (as C. (Peltecanthon) sulcatum). Other: Vulcano and Pereira 1964: 574 (Argentina - as Peltecanthon sulcatus).
Note 1. Gillet (1911b: 32, 34) and Blackwelder (1944: 201, 202) treat Canthon prasinus both as a valid species and as a synonym of the present C. sulcatus .
Note 2. According to Halffter and Martínez (1967: 89), Canthon sulcatus only occurs in eastern Brazil, more precisely in the states of Espírito Santo and Rio de Janeiro and in the southern part of Bahia. We suspect Laporte (1840: 69) based the type locality Cayenne (present-day French Guiana) on a mislabeled specimen, which was then copied in A. Schmidt (1922a: 81) and Blackwelder (1944: 202). The record from Argentina in Vulcano and Pereira (1964: 574) is likely incorrect as well for similar distributional reasons.
