6 Head and bottom of gena with rather broad longitudinal brown stripes. Basal part of supra-anal plate fused with tenth abdominal tergite, triangular, protruding .......................................... T. (Teratura) pulchella Gorochov & Kang

- Head light yellowish brown, vertex and lower frons dark. Supra-anal plate broad, anterior margin of basal part concave ........................................................................................................................... T. (Teratura) cincta (Bey-Bienko)

7 Apex of supra-anal plate with three dentelated protrusion. Basal part of cerci cylindrate, 2/3 subapical lamellar, curved forward ........................................................................................... T. (Megaconema) geniculata (Bey-Bienko)

- Apex of supra-anal plate without three dentelated protrusion...................................................................................... 8

8 Ventral lobe of cercus obviously broadened. Apical half of supra-anal plate with protruding earlike projection, lateral apices with some stout spines, subapical part with a pair of hastate-shaped projections ....................................... ............................................................................................................................. T. (Teratura) hastata Shi, Mao & Ou

- Ventral lobe of cercus narrow and twisted, apex constrictive. Supra-anal plate with a pair of cylindrical projections, lateral apices without any spines................................................................................ T. (Teratura) flexispatha sp. nov.
