( Fig. 26 )

Stegana (Steganina) maymyo Sidorenko, 1997b: 169 (synonymized in Chen & Aotsuka 2004: 2783).

Diagnosis. This species closely resembles S. (S.) kanmiyai Okada & Sidorenko, 1992 in the shape of male terminalia (as fig. 3E–G in Okada & Sidorenko 1992, Fig. 26A–F ), but can be distinguished from the latter by having the aedeagus bifid on distal 1/ 3 in lateral view ( Fig. 26C ); the aedeagus with flagella along anterior margin, lacking serrated process ( Fig. 26B, C ).

Chen; 1♂, 1♀ ( SCAU, Nos. 125496, 97, DNA #2194, 2648), Guanlei, Mengla , Yunnan, 21°38'39''N, 101°09'52''E, alt. 570m, 24.iv.2016, ex tree trunks, J. Huang, Y.L. Wang.
