Figs 3A–I, 4A–E  
 Type material. Holotype ♂, China, Yunnan Province, Lushui County, Pianma Town, Pianma River, Sanjishui power station (26°0.694′N, 98°37.839′E), 22 May 2015, Chi JIN leg. Paratypes: 5♂ 8♀, same data as for holotype; 4♂ 2♀, Yunnan Province, Baoshan City, Mangkuan Town, Sandieshui (25°27.080′N, 98°52.416′E), 20 May 2015, Chi JIN leg.   
 Etymology. The specific name is a combination of the Latin words ‘ lasio ’ which means wooley or downey and ‘ lepsis ’ meaning shiny or iridescent, and refers to visual characters on the abdomen; adjective.   
 Diagnosis. The new species is similar to P. palgongensis (Seo, 1988: 90, figs 27–32) in having a similar SD, but can be distinguished from the latter by: 1) with one strong RTA (two different RTA in the latter); 2) embolus thick (thinner relatively in the latter); 3) thicker, shorter CD (thin, long in the latter); 4) BU crescent, ear-like (not crescent in the latter). The new species also can be distinguished from P. pennatus (Yaginuma, 1967 b: 102, figs 3i–k) by: 1) with one strong RTA (two different RTA in the latter); 2) embolus thicker (thin relatively in the latter); 3) thicker, shorter CD (thin in the latter); 4) BU crescent, ear-like (not crescent in the latter).
