Longzhua loculata n. gen. n. sp., a new Pennsylvanian Archaeorthoptera (i.e., stem-Orthoptera), is described from the Tupo Formation based on 64 specimens, including an individual with parts of body and legs preserved. The range of intra-specific variation in forewing venation pattern is documented in detail. Well-preserved isolated hind wings are associated with forewings based on more complete material. The combination of character states exhibited by the new species indicates relationships with the extinct order Cnemidolestodea. Mandibular and prothoracic morphology suggest that Longzhua loculata n. gen. n. sp. had carnivorous and predatory habits.
