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. Female: Unknown. Holotype ♂, Mt. Erlang (Yuanyangyan, 1900 m; 29°51′N, 102°12′E), Sichuan Prov., 08 Ⅷ 1980, coll. 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. Etymology: This new species is named as Nepalonesia fanzidei in honor of Prof. Fan Zide for his great contributions on the studies of medical Entomology especially to insect flies in China work.
