(Figs. 21, 24)

Specimens examined. Holotype, male. China, Sichuan province, Wolong, 2000 m, sweep-net, 22.VII.2006, Zhuan Lu [SM01152].

Description (Male). Color. The head is bleached, pale brown; antenna brown; thorax, abdomen and hypopygium yellowish-brown; palpus and legs yellow; wing fumose. Head (Fig. 21C, D). Eye bridge with 3 rows of facets. Prefrons and clypeus not well seen. Basal segment of palpus with 3 setae; 2nd segment with 6 setae; 3rd segment with 9 setae. Length/width of 4th flagellomere: 2.97. Thorax. Anterior pronotum with 9 setae, episternum 1 with 7 setae. Wings. Wing length 2.16 mm, width/length: 0.37. c/w: 0.43. R1/R: 0.80. r-m, stM, M1 and M2 bare, Cu1 and Cu2 bare. Legs. Foretibia with a comb of 8 setae (Fig. 21E). Length of spur/width of foretibia 1.67. Length of femur/length of metatarsus: foreleg 0.85. Length of metatarsus/length of tibia: foreleg 0.91, hind leg 0.53. Length of hind tibia/length of thorax 1.15. Foretibia with 1 dorsal, 4 ventral, 2 prolateral and 5 retrolateral spinose setae. Midtibia without dorsal spinose setae. Hypopygium (Fig. 21A, B). Sternite 10 with 1 seta on each half.

Distribution. China (Sichuan, Fig. 24 ).

Remarks. By its bare M and Cu wing veins, an inflated gonostylus, an apically located dorsal lobe with five long magesetae, and a richly setose intercoxal lobe on the hypopygium, the new species is similar to P. plusiochaeta Hippa & Vilkamaa, 1991 . But it differs from P. p l u s i o c h a e t a by a wider dorsal lobe on a more strongly inflated gonostylus, five much longer megasetae on the dorsal lobe, a tegmen with medial shoulders and a narrower intercoxal lobe on the hypopygium.

Etymology. This species is named after its long megasetae on the dorsal lobe on gonostylus, from the Latin adjective longispinus, meaning long megasetae.
