摘要:
Three new species of the fossil Lower Cretaceous family Praeichneumonidae are described from the Lower Cretaceous of Transbaikalia (Russia, Buryatia, Khasurty locality): Praeichneumon dzhidensis sp. nov., P. khamardabanicus sp. nov., and P. zakhaaminicus sp. nov. One poorly preserved specimen, Praeichneumon sp., is described. Rudiments of the second anal vein A2 and internal vein a(1)-a(2) and bullae in crossveins of the fore- and hindwing are described in Praeichneumonidae for the first time.
