Phylogeny Of The Oniticellini And Onthophagini Dung Beetles (Scarabaeidae, Scarabaeinae) From Morphological Evidence, T. Keith Philips

Biology Faculty Publications

A phylogenetic study was conducted to hypothesize relationships of most of the genera of the Oniticellini and Onthophagini for the first time using morphological characters from a diverse array of external and internal sclerites. The monophyly and sister relationship of both tribes was found using Bayesian and parsimony analyses with heavily to moderately weighted data. An alternative hypothesis based on parsimony analyses of unweighted or slightly weighted data show a paraphyletic Oniticellini without the Onthophagini, although recognition of the subtribe Helictopleurina as a tribe would eliminate non-monophyly.

Of the three Oniticellini subtribes, the Helictopleurina and Drepanocerina are monophyletic. There is …
