Stegana (Oxyphortica) belokobylskiji Sidorenko, 1997a: 66 .

Stegana (Steganina) belokobylskiji Sidorenko, 1998: 298 .

Diagnosis. This species closely resembles S. (S.) nigrolimbata in the shape of male terminalia (as fig. 6 in Zhang et al. 2014, Fig. 18 ), but can be distinguished from the latter by having the brownish yellow body color ( Fig. 4E, F ); the surstylus distinctly broadened distally ( Fig. 18B ); the filar processes of aedeagus medially curved inward in ventral view ( Fig. 18C ).
