Prosciara ellipsoidea Shi & Huang, sp. nov. (Figs. 6, 24) Specimens examined. Holotype, male. China, Sichuan province, Labahe, 1200 m, sweep-net, 16.VII.2006, Xiao- Ling Niu, [SM01146]. Description (Male). Color. The head is bleached, pale brown; thorax, abdomen and hypopygium yellowishbrown; antenna, palpus and legs yellow; wing fumose. Head (Fig. 6 C, D). Eye bridge with 3 rows of facets. Prefrons with 41 setae. Clypeus with 1 seta. Basal segment of palpus with 2 setae; 2nd segment with 4 setae; 3rd segment with 5 setae. Length/width of 4th flagellomere: 2.73. Thorax. Anterior pronotum with 5 setae, episternum 1 with 12 setae. Wings. Wing length 2.99 mm, width/length: 0.35. c/w: 0.63. R1/R: 0.89. r-m with 3 setae, stM bare, M1 and M2 with numerous setae, Cu1 with numerous setae and Cu2 bare. Legs. Foretibia with a comb of 9 setae (Fig. 6 E). Length of spur/width of foretibia 1.73. Length of femur/length of metatarsus: foreleg 0.82. Length of metatarsus/length of tibia: foreleg 0.80, hind leg 0.55. Length of hind tibia/length of thorax 1.70. Foretibia with 0 dorsal, 0 ventral, 2 prolateral and 2 retrolateral spinose setae. Midtibia without dorsal spinose setae. Hypopygium (Fig. 6 A, B). Sternite 10 with 1 seta on each half. Distribution. China (Sichuan, Fig. 24). Remarks. By its wing length, setose M and Cu1, and the shape of the intercoxal lobe on the hypopygium, the new species resembles P. latilingula. They may be distinguished by an apically located dorsal lobe on the gonostylus and its six megasetae, and a narrower tegmen in the hypopygium in P. ellipsoidea; a subapically located dorsal lobe on the gonostylus and its five megasetae in P. latilingula. By its apically located dorsal lobe on the gonostylus, P. ellipsoidea is also similar to P. plusiochaeta Hippa & Vilkamaa, 1991 and P. prosciaroides Hippa & Vilkamaa, 1991, but the latter two species have bare M and Cu wing veins. Etymology. This species is named after its oval shape of the gonostylus, from the Latin adjective ellipsoideus, meaning oval.
