Figure 6 in The evolution of Bolbites onitoides (Coleoptera: Scarabaeidae: Phanaeini): its phylogenetic significance, geographical polychromatism and the subspecies problem

Figure 6. Sexual dimorphism on the hind legs of B. onitoides. A, B, metacoxae: A, male; B, female. Note the plate-like projections and the long spines directed posteriorly in the male and which are lacking in the female. C, D, metafemora and metatibiae: C, male; D, female. Observe the ridge on the posterior edge of the metafemora and the sharp ridge on the external and internal edges of the metatibiae of the males, all of which are absent in females.
