The Nearctic leafhopper genus Errhomus Oman was recently revised by Oman (1987) and Hamilton and Zack (1999). Although these researchers generally agreed in their results, there were some variations in species and subspecies level designations. Both studies employed a variety of tools including morphological and biogeographical analyses. The biogeographic history of the genus is relatively well understood, and the taxon is ideally suited for a molecular study that will add to the biogeographic and morphological analyses. In the current study, we employed mitochondrial DNA sequencing in order to better elucidate the phylogenetic relationships among members of the subgenus Errhomus (Erronus). Portions of the NADH dehydrogenase subunit 1 (ND1) and the leucine (CUN) transfer RNA genes were sequenced. Both parsimony and likelihood analyses revealed a paraphyletic Errhomus (Erronus).
