Small insects. The length of the front wing is about 25 mm. It differs from closely related species in the venation of wings. The costal field is somewhat wider than the subcostal field in the basal quarter of the wing. Anterior branches of SC and R veins simple and straight. RS starts in front of the top of SC. Vein RS has five branches; M two-branched. CuA has four branches. The species was first described by fingerprints in 2018 by Russian paleoentomologist Daniil Aristov ( Paleontological Institute of the Russian Academy of Sciences , Moscow , Russia ). Among sister taxa: Kamamica , Kungurembia , Paralongzhua , Permedax , Tillyardembia [1] [2] .
