Etymology.
In honorof an outstanding paleoentomologist, Prof. Dr. Alexandr Rasnitsyn.
Holotype.
PIN, no. 3840/1351, well-preserved forewing (part and counterpart), with apex missing.
Paratypes.
PIN, no. 3840/733, 1363, 1371, incomplete forewings.
Locality and horizon.
Isady locality, Vologda Province, North European Russia; Poldarsa Formation, uppermost Severodvinian (Lower Wuchiapingian), Upper Permian.
Diagnosis.
Similar to Permopsyche issadensis ingeneral venation scheme, but of larger size, with MA fork shortened, intercubital space widened, and wing membrane almost uncolored.
Description.
Forewing length/width ratio about 2.8-3:1; anterior margin nearly straight; apex obtuse to rounded. Costal space very narrow along its entire length. MA fork distinctly shorter than RS fork. MP unsclerotized for more than 1/2 of its length. CuA base long, nearly transverse, M5 present or lost. Intercubital space rather expanded. Wing membrane mostly uncolored, with small diffuse dark patch at center of wing.
