Diagnosis. Most similar to P. thallina , with an expanded distal part of the telopodite bearing a large rounded lateral lamella and a hook-shaped process pointing anterodistad. Different in the shape and orientation of the distal lamella, laterally positioned and folded 180 degrees and a shorter mesal coxal process. Descriptive notes. Male holotype 55 mm long, 2.3 mm wide, general colour brown, 55 podous +2 apodous PTs, coxa of leg pairs 1 and 7 with two processes ( Wang and Zhang 1993 ; Wang 1996 ), head with a large projection on the vertex ( Wang 1996 ). Male sexual characters. (based on Wang and Zhang 1993 : fig. 19) Leg-pair 7 with two processes on coxa. Gonopods . Parallel and slightly diverging. Each gonopod with two uniformly setose, clavate prefemoroidal processes ( pf1 and pf2 ), one large falcate coxal process narrowing at mid-length and apically projecting in a pointed tip, reaching the distal part of the telopodite. Telopodite ( T ) with a stout stem, distally expanding in a larger process projecting in a broad lateral folded lamella and a thin curved mesal process pointing anterodistad, apically bifurcated to accommodate the solenomere ( s ) and parasolenomere ( ps ). Distribution. Shangrila County, Yunnan, China (Fig. 28 ). Comments. Species known only from its original description.
