FIGURE 16. Stegana ( Steganina ) bacilla Chen & Aotsuka, 2004 from Mengla, Yunnan, China, male terminalia. A. Epandrium, surstylus, and cercus in lateral view; B. Surstylus in ventral view; C, D. Hypandrium, pregonite (pg), aedeagus, and phallapo- Remarks. The specimens collected from Yunnan , China slightly differ from the type material from Ryukyu Islands, Japan (as fig. 9 in Chen & Aotsuka 2004) in the shape of distal portion of aedeagus and aedeagal sheath in ventral view ( Fig. 16C, E ). They were conservatively identified as conspecific. Specimens examined.
