Frolov, A. V. & Akhmetova, L. A. 2015. New data on the rare Afrotropical scarab beetles Orphnus drumonti Frolov and Delopleurus naviauxi Frolov et Cambefort (Coleoptera, Scarabaeidae, Orphninae and Scarabaeinae). Biodiversity Data Journal, 3: e5444.

The scarab beetle genera Orphnus Macleay and Delopleurus Boheman are most speciose in the Afrotropical region. However, a number of species are only known from type specimens, sometimes only from one sex. New locality records of Orphnus drumonti Frolov (Orphninae) and Delopleurus naviauxi Frolov et Cambefort (Scarabaeinae) are given. The previously unknown female of the former and male of the latter species are described.

Abstract—A new species of the genus Orphnus MacLeay, 1819 is described from Kisantu (Democratic Republic of Congo). The new species is similar to O. striatopunctatus Felsche in having a long bifurcated clypeal horn in the male, but can be distinguished from it by the shape of the parameres and longitudinal ridges on the pronotum, relatively slender body, and more slender clypeal horn.
