Abstract
A new genus and four new species are described from the Upper Mesozoic locality of Khasurty, Western Transbaikalia: Mesobaetis crispa sp. nov. and Proameletus branchiatus sp. nov. from the family Siphlonuridae s. l., Furvoneta khasurtensis sp. nov. from Mesonetidae, and Baikalogenites firmus gen. et sp. nov. from the family Hexagenitidae. One poorly preserved specimen is identified as Mesogenesia from the family Mickoleitiidae. The unique mayfly generic assemblage of this locality, its possible age, and ecology are discussed.
