摘　　要：记述纹石蛾科弓石蛾亚科1新纪录属,美赛弓石蛾属Maesaipsyche,及1新种,即细齿美赛弓石蛾Maesaipsyche serrulata Sunet Yang,sp.nov.(广西),其阳具缺阳基侧突而与Maesaipsyche mekongensis Mey相似,但新种中附肢背缘近端部具齿突、外侧缘具细齿。并记述绒弓石蛾属Parapsyche1新种,即北京绒弓石蛾Parapsyche beijingensis SunetMorse,sp.nov.(北京),该种肛上附肢与第10节完全愈合,阳具特别发达,与Parapsychek china Schmid相似;但新种阳茎基背突为1对瘤状突,其上着生短刺,阳茎基背突上方具1兜状结构,背面观时端部膨大成圆盘。新种模式标本保存于南京农业大学昆虫标本馆。The genus Maesaipsyche is found new to Chinese fauna. Maesaipsyche serrulata Sun et Yang, sp. nov. （Guangxi） and Parapsyche beijingensis Sun et Morse, sp. nov. （Beijing） are described and illustrated. Type specimens of the new species are deposited in the Insect Collections of Nanjing Agricultural University.Maesaipsyche serrulata Sun et Yang, sp. nov. （Figs.1-7）Length of forewing 7mm. Body yellowish brown. The new species is close to Maesaipsyche mekongensis Mey 2001 from Laos in the absence of parameres, but differs from it in ： 1） the intermediate appendages are simple, each with a sharp, dorsal tooth at 1/4 distance from the apex when viewed laterally; 2） the new species has a row of fine teeth on the lateral margin of each intermediate appendage, but these lateral margins are smooth in M. mekongensis. Holotype ♂, Guangxi Province, Longlin Co., Jinzhongshan Provincial Forest Preserve, waterfall of Wuchonggou Stream, 800 m West of Wuchong Village （24.67°N, 104.88°E; alt. 775m） , 10June 2004, collected by J. MORSE and SUN Chang-Hai. Paratype 1♂, same data as holotype.Etymology. ＂serrulatus＂ meaning ＂fine teeth,＂ with reference to the row of fine teeth along the outer margin of each intermediate appendage.Parapsyche beijingensis Sun et Morse, sp. nov. （Figs.8-15）Length of forewing 12.5mm. Body black brown. The new species is somewhat similar to Indian species Parapsyche kchina Schmid because both species have the preanal appendages fused with segment X and complicated phallic apparatus. However, in the new species the dorsal process of the phallobase is paired, capitate and setose, with a large, semi-membranous cover dorsally. Holotype ♂, Beijing City, Songshan National Nature Reserve, small stream beside Dazhuangke Village （40.48°N, 115.73°E; alt. 1000m） , 19 June 2005, collected by ZHOU Xin. Paratypes 14♂♂, same data as holotype.Etymology. The new species is named after its type locality-Beijing.
