Stegana (Steganina) kanmiyai Okada & Sidorenko, 1992: 419 .

Diagnosis. This species is similar to S. (S.) lancang sp. nov. in the shape of male terminalia ( Figs. 25 , 46A–G ), but can be distinguished from the latter by having the cercus lacking pubescence (Fig. 25A); the aedeagus with numerous minute, serrated processes along anterior margin and pubescence anteromedially (Fig. 25C, D).
