Abstract

The genus Lapideacassis Black [= Scampanella Forchheimer & Stradner; Pervilithus Crux] is synonymized under Mennerius Luljeva. The following new combinations are established: M. asymmetricus (Perch-Nielsen) Ovechkina comb. nov., M. bispinosus (Perch-Nielsen) Ovechkina comb. nov., M. blackii (Perch-Nielsen) Ovechkina comb. nov., M. cornutus (Forchheimer & Stradner) Ovechkina comb. nov., M. glans (Black) Ovechkina comb. nov., M. magnificus (Perch-Nielsen) Ovechkina comb. nov., M. mariae (Black) Ovechkina comb. nov., M. tricornus (Wind & Wise) Ovechkina comb. nov., M. trispinus (Perch-Nielsen) Ovechkina comb. nov., M. varius (Crux) Ovechkina comb. nov., and M. wisei (Perch-Nielsen) Ovechkina comb. nov. Descriptions of Mennerius longus Luljeva and M. morosus Luljeva (both from the Turonian of the Ukraine) are emended. For the first time, Mennerius sp. cf. M. bispinosus is recorded from the Campanian of the Ukraine, M. cornutus and Mennerius sp. cf. M. bispinosus from the Lower Maastrichtian of Russia, and Mennerius sp. from the Cenomanian of Israel; notes on newly recorded species are provided.
