Revision of the genus Delopleurus with description of new species from Africa

Frolov, A.V. 2014. Revision of the genus Delopleurus Boheman (Coleoptera: Scarabaeidae: Scarabaeinae) with description of new species from Africa. Journal of Natural History, 49: 1-25. 

The genus Delople‚Äčurus Erichson, 1847, is revised. Five new species are described from Africa: Delopleurus naviauxi sp. nov., Delopleurus krikkeni sp. nov., Delopleurus darrenmanni sp. nov., Delopleurus fossatus sp. nov. and Delopleurus pubescens sp. nov. One new synonymy is established (Delopleurus parvus (Sharp, 1875) = Delopleurus cardoni Paulian, 1934, syn. nov.). Lectotype of Delopleurus pullus Boheman, 1857, is designated. Delopleurus janssensi Frey, 1963, is transferred to the genus Metacatharsius Paulian, 1939. A key to the Delopleurus species and locality maps are given.

Genus Delopleurus (Scarabaeidae, Scarabaeinae)

Delopleurus comprises superficially similar, small-sized, dark brown to black, strongly convex beetles distributed in Africa south of the Sahara and in Southern Asia. The genus is commonly classed as dung beetles, however there are no evidence of its association with dung. Available data suggest that the beetles are associated with higher fungi similar to the related genus Coptorhina members of which are obligate feeders of basidiomycetes. Delopleurus is also peculiar in having a disjunctive range including most of the Afrotropical Region and Indian Peninsula. Distribution of the other genera of Sarophorus group is limited to the Afrotropical region.
