Idelinellidae
family of insects (fossil)
Idelinellidae is an extinct family of insects from the Permian and possibly the Late Carboniferous. They closely resemble members of the family Stenoneuridae.
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). In 2004, Aristov transferred the genus Permostriga from Kortshakoliidae to Idelinellidae and described Sylvastriga from the Tshekarda locality in the Koshelevka Formation. In 2012, Aristov and Rasnitsyn transferred the family to the order Eoblattida, and revised the family to include five more genera. Aristov later transferred the genus Permeoblatta to the family Protophasmatidae in 2015. 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.

Why this record matters
“Idelinellidae” is worth following because a concise public description often conceals a longer documentary argument. Here, Idelinellidae, family and insects provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 11, 2026. The linked authority identifier is Q16983504. The first chronological checks are 1997, 2004, 2012 and 2015.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
