Vorbirriidae

Vorbirriidae is a name used in paleontological entomology to refer to a purported family of extinct insects known only from fossil material. The taxon has appeared in scattered catalogs and lists but has rarely been described in detail in primary literature. The available material is fragmentary—often consisting of small fragments of wings or body outlines—making robust diagnosis difficult. Consequently, the validity of Vorbirriidae and the assignment of any included taxa remain unsettled.

Some treatments have treated Vorbirriidae as a formal family within a major insect order, while others have regarded the name as nomen dubium or as incertae sedis pending more complete specimens. As a result, there is no widely accepted consensus on the composition or phylogenetic position of Vorbirriidae. If valid, the group would represent an early-diverging lineage of insects with a distribution inferred from the fossil sites where the material was discovered; however, due to the lack of diagnostic characters preserved in the fossils, specific morphological traits that would place Vorbirriidae within a particular order or superorder have not been reliably established.

No living representatives are known, and the fossil record for the group is limited. The status of Vorbirriidae may be revised or overturned as new discoveries are made or as taxonomic review clarifies the criteria for valid family‑level names in this part of the insect tree.
