Style one-third ventral margin concave, depression with several odontoid processes, keel-like, style with 1 or 2 thick subapical bristles ( Figs. 3 F, G, J, K). Aedeagus apex long, gonopore between subapical processes or upper subapical process; aedeagus dorsal apodeme developed, broadened in lateral view, apex rhomboid in ventral view ( Figs. 3 H, I).

Female usually with less dark pigmentation. Face hoary with several dark brown spot; anteclypeus black. Seventh sternite shorter than wide, with median shallow concavity in middle ( Fig. 1 I). Second valvulae, narrowly bladelike, evenly curved dorsally, with few unaligned dorsal teeth; first valvulae sculpture strigate ( Figs. 1 J–M). Etymology. The specific name refers to the several odontoid processes of style.

Material examined. Holotype: ♂, CHINA, Zhejiang Prov., Qingliangfeng peak, 980m, at light, 5-viii-2011, coll. Wang Yang. Paratypes: 1♀, same data as holotype; 6♂♂, 8♀♀, CHINA, Zhejiang Prov., Qingliangfeng peak, Yunding, 987m, at light, 8-viii-2011, coll. Wang Yang; 3♂♂, 1♀, CHINA, Henan Prov., Jigongshan Mountain, at light, 14-vii-1997, coll. Du Yuzhou; 3♂♂, 1♀, CHINA, Fujian Prov., Sanming Town, Longxishan Mountain, 3- viii-2013, coll. Fengling; 1♀, CHINA, Fujian Prov., Wuyishan Mountain, Tongmu Village, at light, 27-vii-2013, coll. Fengling.
