Figure 3. The 50 in Size and shape interspecific divergence patterns partly reflect phylogeny in an Onthophagus species-complex (Coleoptera: Scarabaeidae)

Figure 3. The 50% majority rule consensus phylogenetic tree from the Bayesian Markov chain Monte Carlo (MrBayes) analysis of mtDNA cytochrome oxidase subunit 1 (cox1). Sequences with posterior probabilities P> 70% for internal node are shown. OF, Onthophagus fracticornis; OO, Onthophagus opacicollis; OS, Onthophagus similis. Specimens belonging to Onthophagus vacca and Onthophagus nuchicornis European populations were used as an outgroup (indicated as Palaeonthophagus spp. in the trees, courtesy of Dirk Ahrens).
