| Abstract: | Three new genera and four new species, all assigned to Maimetshidae, are described from the Turonian (U. Cretaceous) of Orapa in Botswana (southern Africa), viz., Afrapia globularis gen. et sp. n.,A. variicornis sp. n., Afromaimetsha robusta gen. et sp. n., and Maimetshorapia africana gen. et sp. n. The genera Andyrossia Rasnitsyn & Jarzembowski, 2000 from the Barremian (L. Cretaceous) of the Weald Clay (southern England) and Guyotemaimetsha Perrichot, Nel & Neraudeau, 2004 from the Albian (L. Cretaceous) of France are also transferred to Maimetshidae. Cretogonalys Rasnitsyn, 1977 from the Cenomanian (U. Cretaceous) of northern Siberia may also belong here. These results extend the known duration of Maimetshidae over the entire middle part of the Cretaceous (from the Barremian to the Santonian), its geographic distribution over the western half of the Old World (from northernmost Siberia to western most Europe and southern Africa), and its taxonomic diversity to at least six genera and seven species, with the diversity possibly centred in Africa. The taxonomic and phylogenetic positions of Maimetshidae are discussed. |
