Parameres as in Fig. 28. Aedeagus shaft long, basal half strongly dorsoventrally depressed, distal half narrow and cylindrical, serrate laterally at base on dorsal surface; with two long processes arising at midlength on each side of shaft, basally each process with a lateral lamellate serrate lobe (Figs 29, 30).

Type material
Holotype male. China: Hainan Province, Wuzhi mountain, 13 April 2009, coll. Zaihua Yang.
Etymology
The new species name is derived from the serrationsat midlength of the aedeagal shaft and base of the aedeagal processes.
Remarks
Thenew species can be distinguished mainly by the relatively rather uniform width of the subgenital plate and shape of the aedeagal shaft and configuration of its process as noted in the description.
