Systematics of the Rubidgeinae (Therapsida: Gorgonopsia).

ABSTRACT: The subfamily Rubidgeinae, containing the largest known African gorgonopsians, is thoroughly revised. Rubidgeinae is diagnosed by the absence of a blade-like parasphenoid rostrum and reduction or absence of the preparietal. Seven rubidgeine species from the Karoo Basin of South Africa are recognized as valid: Aelurognathus tigriceps, Clelandina rubidgei, Dinogorgon rubidgei, Leontosaurus vanderhorsti, Rubidgea atrox, Smilesaurus ferox, and Sycosaurus laticeps. Rubidgeines are also present in other African basins: A. tigriceps and S. laticeps occur in the Upper Madumabisa Mudstone Formation of Zambia, and D. rubidgei, R. atrox, and the endemic species Ruhuhucerberus haughtoni comb. nov. and Sycosaurus nowaki comb. nov. occur in the Usili Formation of Tanzania.
