	PIN 4626/462 Mersituria ludmilae, Vasilenko, 2005 Location relative to the calibrated node: Crown [show fossil details] Locality: Chernovskie Kopi, left bank of Ingoda River, 18 km southwest of Chita city, Chita Region, Chita Dist Stratum: Doronino Formatio Geological age: Jurassic, Mesozoic More information in Fossilworks PaleoBioDB

	phylogenetic justification Several wing characters support the attribution of this fossil to Hemiphlebiidae, close to the Cretaceous genus Parahemiphlebia, such as tiny size with few cells in the wing venation, basally open discoidal cell in forewings, non-aligned postnodal and postsubnodal crossveins, and the kink of RP1 at the stigmal brace vein.
