Length of spur/width of foretibia 2.22. Length of femur/length of metatarsus: foreleg 0.92. Length of metatarsus/length of tibia: foreleg 0.67, hind leg 0.53. Length of hind tibia/length of thorax 2.67. Foretibia with 2 dorsal, 3 ventral, 2 prolateral and 3 retrolateral spinose setae. Midtibia with 2 dorsal spinose setae. Hypopygium ( Fig. 8 A, B). Sternite 10 with 1 seta on each half.

Distribution. China (Yunnan, Fig. 24 ).

Remarks. By its setose M and Cu1, and the form of the hypopygium, the new species is similar to P. Parallela Vilkamaa & Hippa, 1996. But the two species may be distinguished by three megasetae on a slender dosal lobe on the gonostylus, and a much longer tegmen with weak medial shoulders in P. paucispina , while four megasetae on a wide dorsal lobe on the gonostylus, and a short tegmen in P. parallela .

Etymology. This species is named after its few megasetae, only three ones on the dorsal lobe on the gonostylus, from the Latin adjective paucispinus, meaning few megasetae.
