Abstract
The subfamily Protoscelinae from the Middle to Late Jurassic of Karatau is transferred from the family Chrysomelidae to the family Anthribidae. The genus Protoscelis, comprising five species, is reviewed. Males and females of the genus are described and keys to the identification of male and female specimens are provided. The new species P. medvedevi sp. nov. is described. The generic names Cerambyomima Medvedev, 1968, Pseudomegamerus Medvedev, 1968 and Protosceloides Medvedev, 1968 are synonymized under Protoscelis Medvedev, 1968, and the species Pseudomegamerus grandis Medvedev, 1968 is synonymized under Cerambyomima longicornis Medvedev, 1968. The new combinations Protoscelis longicornis (Medvedev, 1968) comb. nov. and P. nitidicornis (Medvedev, 1968) comb. nov. are established.
