Abstract

OCAMPO, Federico Carlos  and  MOLANO, Fredy. Revision and biogeography of the Neotropical dung beetle genus Scybalophagus (Coleoptera: Scarabaeidae). Rev. Soc. Entomol. Argent. [online]. 2011, vol.70, n.3-4, pp.231-253. ISSN 0373-5680.

The South American genus Scybalophagus Martínez is comprehensively revised. The genus now includes five species, distributed in Argentina, Chile, Bolivia and Peru. All species are redescribed and diagnostic characters are provided along with illustrations of each species. Lectotypes are designated for Canthon lacordairei Laporte, 1840 (now Scybalophagus lacordairei) and Canthon rugosus Blanchard, 1845 (now Scybalophagus rugosus). Scybalophagus zumpti (Frey, 1963) (=Epirinus zumpti Frey) is now considered a junior synonym of S. rugosus (Blanchard). The biogeography of the genus and of each species is discussed and predictive distributions, based on environmental niche modeling, are provided for all species. Information on the biology and natural history of Scybalophagus species is discussed.
