Fig. 2 in A monographic revision of the Neotropical dung beetle genus Sylvicanthon Halffter & Martínez, 1977 (Coleoptera: Scarabaeidae: Scarabaeinae: Deltochilini), including a reappraisal of the taxonomic history of 'Canthon sensu lato'

Fig. 2. The German coleopterist Edgar von Harold (1830–1886), one of the first specialists in scarab beetles and author of the only 19th century revision of Canthon Hoffmannsegg, 1817, in which 97 species were recognized as valid, 46 as new. Harold described two species today positioned in Sylvicanthon Halffter & Martínez, 1977: S. aequinoctialis (Harold, 1868) comb. nov. and S. candezei (Harold, 1869) (portrait courtesy of Editha Schubert, from the archives of the Senckenberg Deutsches Entomologisches Institut; title page of Harold's revision of Canthon scanned from an original copy housed at the first author's personal library).

Fig. 1. Authors who initiated the studies on 'Canthon sensu lato' in the first half of the 19th century. A. The German naturalist Johann Centurius Graf von Hoffmannsegg (1766–1849), author of the genus Canthon (image courtesy of Editha Schubert, from the archives of the Senckenberg Deutsches Entomologisches Institut). B. The French entomologist Pierre André Latreille (1762–1833), author of Ateuchus septemmaculatus Latreille, 1807, species treated in detail by Hoffmannsegg (1817) in his description of Canthon. Latreille was also the author of Coprobius, name considered valid for decades before being synonymized with Canthon by Harold (1868a) (image courtesy of the United States National Library of Medicine).

The presence of this form of tarsal claw was seen as evidence for a close phylogenetic relationship between several groups of Scarabaeinae distributed over the continents of former Gondwana. A.
