The type specimens of South American dung beetles, Part II : the species described by the Austrian coleopterist Ludwig Redtenbacher (1814-1876) in the 1868 part of the " Reise der österreichischen Fregatte Novara um die Erde" (Insecta: Coleoptera, Scarabaeidae, Scarabaeinae) / F.

Discussed and illustrated are the type specimens of the nine species names established by Redtenbacher (1868) for South American dung beetle taxa: Canthon auricollis, C. cyanopterus, C. fulgidus, C. lamproderes, C. ornatus, C. puncticollis, C. quadripunctatus, Choeridium foveicolle, and C. platymerum. Lectotypes are designated for all of them, and the following taxonomic conclusions are presented: firstly, it was seen that the name Canthon auricollis was previously misapplied to a species taxon in the Canthon subgenus Peltecanthon, whereas in fact it represents a species of the subgenus Canthon s.str., where it is transferred to; a former junior synonym of it, C. splendidus Schmidt, 1922, is revalidated to name the species of the subgenus Peltecanthon called by former authors " C. auricollis". Secondly, Canthon puncticollis is transferred to the genus Canthidium, with Canthidium excisipes baltha Sa R, 1939 its new junior synonym. Finally, Canthon corpulentus Harold, 1868 is revalidated from its synonymy with Canthon (Francmonro-sia) lamproderes Redtenbacher, 1868 to denote a species in the subgenus Francmonrosia, while C. lamproderes Redtenbacher, 1868, is considered a new junior synonym of Canthon (Francmonrosia) rutilans Castelnau, 1840. Lectotypes are also designated for C. corpulentus and C. rutilans, and the holotype of C. excisipes is illustrated.
