Abstract

On distribution and morphology of some Onthophagus species in Switzerland (Coleoptera: Scarabaeidae). – On the basis of 1097 specimens from 12 collections, the distribution of ten dung beetle species of the genus Onthophagus (Scarabaeidae) in Switzerland is compiled and shown in distribution maps: O.taurus-group: O.illyricus, O.taurus; O.fracticornis-group: O.fracticornis, O.opacicollis, O.similis; O.ovatus-group: O.baraudi, O.grossepunctatus, O.joannae, O.ovatus, O.ruficapillus. New characters of the female genitalia allow species identification of O.fracticornis, O.similis, and O.ruficapillus. Reduced male characters of a small O.gibbulus are described.
