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 ).
