( Figs. 1 , 24 ) Specimens examined. Holotype , male. China , Yunnan province, Baoshan, Nankang, Gaoligong Nature Park, 2181 m , sweep-net, 24°49.729ʹN, 98°46.074ʹE, 11.V.2009 , Su-Jiong Zhang [SM00896]. Description (Male). Color . Head dark brown; antenna, thorax, abdomen and hypopygium yellowish-brown, mesonotum brown; palpus and legs yellow; wing fumose. Head ( Fig. 1 C, D). Eye bridge with 3 rows of facets. Basal segment of palpus with 2 setae; 2nd segment with 6 setae; 3rd segment with 8 setae. Length/width of 4th flagellomere: 1.45. Thorax . Anterior pronotum with 6 setae, episternum 1 with 7 setae. Wings . Wing length 2.54 mm , width/length: 0.37. c/w: 0.57. R1/R: 1.03. r-m with 3 setae, stM with a few setae, M1 and M2 with numerous setae, Cu1 with numerous setae and Cu2 bare. Legs . Foretibia with a comb of 7 setae ( Fig. 1 E). Length of spur/ width of foretibia 1.89. Length of femur/length of metatarsus: foreleg 1.09. Length of metatarsus/length of tibia: foreleg 0.67, hind leg 0.53. Length of hind tibia/length of thorax 1.54. Foretibia with 0 dorsal, 1 ventral, 2 prolateral and 2 retrolateral spinose setae. Midtibia without dorsal spinose setae. Hypopygium ( Fig. 1 A, B). Sternite 10 with 3 setae on each half. Distribution. China (Yunnan, Fig. 24 ). Remarks. By its relative wing length, setose M and Cu1, the form of the gonostylus and the subapically located dorsal lobe, the new species resembles P. bifida Hippa & Vilkamaa, 1991 and P. mima Hippa & Vilkamaa, 1991 . But the intercoxal lobe of the hypopygium is not present in P. oligotricha , whereas it is distinctly present in P. bifida and P. m i m a . The tegmen is wider than length in P. oligotricha , while as long as or longer than wide in P. bifida and P. mima . Additionally, P. oligotricha differs from P. bifida by having a wider gonostylus, with a dorsal lobe extended distally as far as apex of the gonostylus. This species differs from P. mima by a wider gonostylus, with five megasetae on the dorsal lobe, while four in P. mima . Etymology. This species is named after its few setae on the ventral membraneous area between the gonocoxites, from the Latin adjective oligotrichus , meaning few setae.
