Fig. 44 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. 44. Differences on the parameres of Sylvicanthon mayri sp. nov. and S. monnei sp. nov. (grayish zones represent original membraneous areas). A–B. S. mayri sp. nov. C–D. S. monnei sp. nov. Note that both branches of the apical bifurcation of the parameres of S. mayri sp. nov. are much more divergent than those of S. monnei sp. nov., which makes the internal angle between them more open in the first species (~110º) than in the second (~78º). In the same way, as the inferior branch is much more projected in S. mayri sp. nov. than in S. monnei sp. nov., the angle between the posterior region of that branch and the rest of the paramere is more open in S. monnei sp. nov. (~147º) than in S. mayri sp. nov. (~137º), species that seems to have a strong excavation at this point of the paramere (indicated by red arrow in A).

Fig. 35. Variation on the pilosity at the centre of the hypomeral cavity among members of the bridarollii subgroup. A. Sylvicanthon seag sp. nov. B. S. attenboroughi sp. nov. C–D. S. bridarollii (Martínez, 1949). Note the first two species have the hypomeral cavity entirely glabrous or with setae limited to its periphery (centre always glabrous), whereas S. bridarollii possesses long and dense setae throughout the tegument of the hypomeral cavity.

Fig. 36 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. 36. Clinal morphological variation in S. bridarollii (Martínez, 1949). Note that, from south to north, the colouration of metafemora gradually fades from dark brown to reddish brown and orange with a light-brown base in populations of northern Peru, Ecuador, and Colombia, and that the internal margin of protibiae (indicated by the red arrows) becomes progressively much subtler. Other features varying along this north-south cline are the presence of coarse elongate punctures at the base of metafemora (present in southern populations and absent in the northern ones) and of a fine transverse line on the posterior edge of pronotum (absent in the southern populations). See the text for more details.
