Abstract

The taxonomy and phylogeny of two related species groups of Mexican and Central American Onthophagus are considered. The dicranius group is composed of four species, including two new species, O. asperodorsatus and O. petenensis. The mirabilis group contains three species, one of these new, O. solisi. A fourth new species, O. quetzalis, shares characters with both species groups. All species in these groups are described and illustrated. A suggested phylogeny is presented. Our analysis indicates that these groups, including O. quetzalis, may be more closely related to Indo-Malaysian species than to other New World groups of Onthophagus.

Résumé

On trouvera ici une étude de la taxonomie et de la phylogénie de deux groupes apparentés d’espèces du genre Onthophagus au Mexique et en Amérique centrale. Le groupe dicranius se compose de quatre espèces, dont deux nouvelles, O. asperodorsatus et O. petenensis. Le groupe mirabilis contient trois espèces, dont une nouvelle, O. solisi. Une quatrième espèce nouvelle, O. quetzalis, possède des caractéristiques des deux groupes. Toutes les espèces de ces groupes sont décrites et illustrées et une phylogénie est proposée. Notre analyse indique que ces groupes, y compris O. quetzalis, s’apparentent davantage à des espèces indo-malaises qu’aux autres groupes d’Onthophagus du Nouveau Monde.
