New material. 3 males, China, Sichuan, Wolong, 2000 m, sweep-net, 22.VII.2006, Zhuan Lu [SM01157, SM01158, SM01159]; 2 males, the same data but 21.VII.2006, Xiao-Ling Niu [SM01160, SM01161]; 1 male, China, Sichuan, Wanglang, 2500 m, sweep-net, 25.VII.2006, Zhuan Lu [SM01162].

Description (Male). Color. The head is bleached, pale brown; antenna and thorax pale brown, abdomen and hypopygium yellowish-brown; palpus and legs yellow; wing fumose. Head. Eye bridge with 4 rows of facets. Prefrons with 11–13 setae. Clypeus with 1–2 setae. Basal segment of palpus with 1–2 setae; 2nd segment with 7–10 setae; 3rd segment with 7–10 setae. Length/width of 4th flagellomere: 1.40–2.05 (1.50, the holotype). Thorax. Anterior pronotum with 5–6 setae, episternum 1 with 7–8 setae. Wings. Wing length 2.27–2.52 (2.40, the holotype) mm, width/length: 0.35–0.40. c/w: 0.39–0.63 (0.85, the holotype). R1/R: 0.72–0.82. r-m bare, stM with a few of setae, M1 and M2 with numerous setae, Cu1 with numerous setae and Cu2 bare. Legs. Foretibia with a comb of 4– 7 setae. Length of spur/width of foretibia 1.83–2.16. Length of femur/length of metatarsus: foreleg 1.03–1.36. Length of metatarsus/length of tibia: foreleg 0.60–0.73, hind leg 0.51–0.63. Length of hind tibia/length of thorax 0.97–1.40. Foretibia with 0 dorsal, 2–5 ventral, 2 prolateral and 2 retrolateral spinose setae. Midtibia without dorsal spinose setae. Hypopygium. Sternite 10 with 2 (2–3, the holotype) setae on each half.

Diagnosis. The species is distinguished by setose M and Cu1 on wings; a dorsal lobe on the gonostylus located completely in dorsal side, not visible in ventral view except its three megasetae; a short and wide intercoxal lobe on the hypopygium.

Distribution. China (Sichuan, Taiwan, Fig. 24 ).

Remarks. This species was first recorded in Mt. Alishan, Taiwan (Vilkamaa & Hippa 1996) . It was also described as Phytosciara (Prosciara) flexa Rudzinski, 1996 , which was regarded as a junior synonym of P. f u r t i v a by Menzel and Heller (2006). Vilkamaa & Hippa (1996) described the species based on a single type. The description provided was not comprehensive because many parts of the holotype were distorted or missing. Here we describe the species based on new materials from Sichuan province.
