Abstract

The phylogeny of Tomarus Erichson, 1847 (Coleoptera: Scarabaeidae: Dynastinae: Pentodontini) was explored by parsimony using morphological characters to approach its taxonomic and nomenclature problems. The genus was not supported as a monophyletic group, and the recovered lineages did not match at all any of the previously known classifications. Three different lineages and six monophyletic groups were recovered, which could be treated as independent genera. However, the classification proposed here is as conservative as possible concerning to the creation of many new names and generic taxa.
