Note. Canthon septemmaculatus is variable in color, color pattern, size and luster ( Harold 1868a: 51), and as a consequence a number of varieties, some of them raised to subspecific rank by some authors, have been described. In the absence of a good synopsis, we treat them all as synonyms here. Likewise, some present synonyms that were once described as valid species were variably treated as varieties and subspecies. In addition to this, C. cincticolle Lucas, 1859 has been treated as a variety ( Vaz-de-Mello 2000: 191) and a subspecies ( Halffter and Martínez 1977: 71) of C. septemmaculatus as well as a variety of C. quinquemaculatus ( Harold 1868a: 35; Gillet 1911b: 32; A. Schmidt 1920: 117, 1922a: 79; Balthasar 1939e: 210; Blackwelder 1944: 201; Vulcano and Pereira 1964: 627).
