Idelinellidae is an extinct family of insects from the Permian and possibly the Late Carboniferous. They closely resemble members of the family Stenoneuridae.[1]
Classification history
Idelinellidae was originally established by Storozhenko (1997) to house the genus Idelinella (described from a fossil preserving only a fragment of a forewing), which had previously been included in the family Ideliidae. Idelinellidae itself was classified in the suborder Grylloblattina of the order Grylloblattida (including extant Grylloblattidae as well as many extinct families).[2] In 2004, Aristov transferred the genus Permostriga from Kortshakoliidae to Idelinellidae and described Sylvastriga from the Tshekarda locality in the Koshelevka Formation.[3] In 2012, Aristov and Rasnitsyn transferred the family to the order Eoblattida, and revised the family to include five more genera.[1] Aristov later transferred the genus Permeoblatta to the family Protophasmatidae in 2015.[4] Cui et al. (2024) consider most members of the family as representatives of the total group of Xenonomia (except Rasstriga), though the authors avoided using family names in their data set.[5]
