记述采自中国四川省丽蝇科乌丽蝇族 Melanomyini中的鬃腹丽蝇属 Tricy-cleopsis Villeneuve,1 92 7和尼蚓蝇属 N epalonesia Kurahashi et Thapa,1 994的 2新种 :毛角鬃腹丽蝇 Tricycleopsis pilantenna,sp.nov.;范氏尼蚓蝇 Nepalonesiafanzidei,sp. nov.。
The present paper deals with two new species which belonging to genera Tricycleopsis and Nepalonesia respectively; it is collected from Sichuan Province, China during 1980-1997. The type specimens are deposited in the Shanghai Institute of Entomology, Academia Sinica, Shanghai, China. 1. Tricycleopsis pilantenna, sp. nov. (Figs.1~7) Male: Body length 7.0 mm. This new species is closely related to Tricycleopsis paradoxa Villeneuve, 1927, but differs from the latter in: The 3rd antennal segment with yellowish hairs; intraalar bristles 1+2; gena about 1/3 the eye height; male pregonites curved on basal part. It is also closely related to Tricycleopsis papei Kurahashi, 1998, but differs from the latter in: The 3rd antennal segment with yellowish hairs; intraalar bristles 1+2; surstyli straight on outer margin in posterior view; cerci straight on posterior margin in lateral view. Female: Unknown. Holotype ♂, Mt. Meng (1456m; 30°03′N, 103°01′E), Mingshan, Sichuan Province, 08 Ⅸ 1997, coll. Feng Yan. 2. Nepalonesia fanzidei, sp. nov. (Figs.8~14) Male: Body length 4.5 mm~5.0 mm. This new species is closely related to Nepalonesia pulchokii Kurahashi et Thapa, 1994, but differs from the latter in: The lateral lobe of 5th sternite wholly length of inner margin with densely yellowish hairs which is on apical part pendant like in round or ellipse; 5th tergite on dorsal is redused into an isosceles triangle; male cerci shorter than surstyli, which apical of both piece embrace like in posterior view; surstyli broad plank like in lateral view.

Feng Yan; paratypes: 1♂, 18 Ⅸ 1980; 1♂, 16 Ⅶ 1982; 1♂, 10 Ⅶ 1983; 1♂, 20 Ⅷ 1984; 1♂, 08 Ⅶ 1986; 1♂, 03 Ⅶ 1988, coll. Feng Yan, Yang Shi bin, same localities as holotype; 1♂, Hanyuan (Mt. Jiaoding, 3550 m; 29°22′N, 102°53′E), Sichuan Prov., 01 Ⅷ 1986, same collector as holotype.
