Diagnostic characters. The species can be separated from other East Asian Corynoneura by having an antenna with 10 flagellomeres, AR 0.27; posterior margin of tergite IX slightly bilobed, sternapodeme inverted V-shaped, and inferior volsella digitiform.

Additional description and corrections. AR 0.27 while the original description by Sasa (1989) mentions AR 0.41. Some additional characters should be added: Tentorium 113 µm long, 15 µm wide. Posterior margin of tergite IX slightly bilobed. Sternapodeme inverted V-shaped; coxapodeme 38 µm long; attachment point with phallapodeme placed in caudal third of lateral sternapodeme and directed caudally; phallapodeme strongly curved with projection for joint with sternapodeme placed pre-lateral, extending beyond margin of tergite IX, 88 µm long. Gonocoxite 65 µm long with 3 long setae apically. Gonostylus bent, 30 µm long; megaseta 8 µm long. HR 2.2, HV 3.4. The wing and the hypopygium of the holotype are redrawn ( Figs 9 A– C).
