International audience. A new species of Grylloblattida, Ideliopsina aristovi sp. nov., is described from the Upper Triassic Ominé locality (Momonoki Formation, Mine Group, Japan). It belongs to a typical Triassic genus, Ideliopsina Storozhenko, 1996, which species have been previously reported from the Kyrgyz Republic and the Kazakhstan in Central Asia. The new species shows that the corresponding family, the Ideliidae ranging from the Cisuralian to the Late Triassic, remained widely distributed during the latter period, before its extinction.
