Three new species, a synonymy and taxonomic notes on southern African members of the dung beetle genera Scarabaeus s. str. Linnaeus, 1758 and Escarabaeus Zídek & Pokorný, 2011 (Scarabaeidae: Scarabaeinae)

Abstract

Three new species are described in the dung beetle genera Scarabaeus s. str. L., 1758, and Escarabaeus Zídek & Pokorný, 2011. Two comprise, Scarabaeus karae sp. nov. and Escarabaeus remii sp. nov. and are novelties. The third comprises Scarabaeus geminogalenus sp. nov., which describes a new species previously misidentified by Péringuey in 1901 and involved in a false synonymy by Janssens (1940). Notes are provided on the type specimen of Scarabaeus galenus. A close relative, Scarabaeus vicinus is recorded for the first time. Scarabaeus natalensis is synonymized with Scarabaeus basuto. Relationships and validity of a further five species are discussed: Scarabaeus convexus with S. spretus and S. rusticus; S. ebenus with S. interstitialis. The type specimen of Scarabaeus rixosus is also discussed galenus. Distribution maps are provided for the new species and those in the S. galenus species complex.
