Trichonotuloides aphoderrans, new species (Coleoptera: Scarabaeidae), is described from Arizona, USA. This represents the fi rst member of the genus reported north of Mexico. A brief discussion on its biology is presented.
We describe four new species of winter-active Aphodius (sensu lato) from pocket gopher burrows in Arizona, Utah, Kansas, and Nebraska: A. cacabatus, A. paulseni, A. skillmani, and A. utopensis. Diagnostic characters of all four species are illustrated.
