Diagnosis. This and the next species are very similar in the male genitalia for both having recurved costal extensions, tapering at both ends but broad mesally. Also the distal half of the valva are narrower than in other congeners. The males of both species have a semicircular eighth abdominal tergite, and are distinctive in the eighth sternite by the large curved lateral processes, which are bifid apically, and with another tooth mesally. Inoue (2006) stated that sometimes there are two spines mesally, of which one may be forked. For additional comparisons see the following species descriptions.

Distribution. China ( Taiwan, Hainan, Guangxi, Yunnan, Tibet), Philippines, Malaysia, Indonesia.

Remarks. One male specimen (Slide No. 1244) from Jianfengling, Hainan is different from others by having two small protrusions on the terminal margin of the saccus, which is only present in this single specimen. When more specimens having the same saccus were found, a distinct species would be erected.
