Data from: A new species of the Triassic genus Ideliopsina (Grylloblattida: Ideliidae) from the Ominé locality (Momonoki Formation, southwest Japan)

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.
