| ABSTRACT Ateralphus Restello, Iannuzzi & Marinoni, 2001 is a Neotropical genus of longhorn beetles composed of nine species. This genus was proposed from splitting Alphus White, 1855 into other two genera: Ateralphus and Exalphus Restello, Iannuzzi & Marinoni, 2001. Even though Ateralphus (nine species), Alphus (four) and Exalphus (18) were recently revised, their validity has not been tested using phylogenetic methods. In this study, we carried out a cladistic analysis of Ateralphus and its related genera, Alphus and Exalphus, based on 44 morphological characters of the adults, to test their monophyly and infer the relationships between their species. Our results support the monophyly of the three genera and recovered two clades that corroborate... |
