Synonym: Aulonocnemis monstrosa, Harold. Annali del Museo civico di Storia naturale di Genova. vol. X (1877) p. 92. I was insufficiently acquainted with the genus Aulonocnemis when I referred to it the above mentioned species. In the following ”Note“ I will mention the characteristics by which this genus of Klug is shown to be a true representative of the Copridae. Only provisionnally I retain the monstrosus among the Ataenius. The species indeed possesses the more essential characteristics of this genus, but the very peculiar armature of the anterior tibiae, as well as the shortness of the posterior tarsi seem to require a new generic subdivision.
