摘　　要：记述小石蛾属Hydroptila的4新种,双钩小石蛾H.biuncialis Zhouet Yang,sp.nov.(江西),细角小石蛾H.leptocera Zhouet Yang,sp.nov.(江西,广西),内刺小石蛾H.introspinata Zhouet Sun,sp.nov.(黑龙江)和长板小石蛾H.longitabularis Zhouet Yang,sp.nov.(广西);编写了我国小石蛾属分种检索表。模式标本保存于南京农业大学昆虫标本馆。In this paper, four new species, Hydroptila biuncialis Zhou et Yang, sp. nov., Hydroptila leptocera Zhou et Yang, sp. nov., Hydroptila introspinata Zhou et Sun, sp. nov. and Hydroptila longidorsalis Zhou et Yang, sp. nov. are described from China. A key to the Hydroptila species presently known from China is given. Type specimens are deposited in the Insect Collection of Nanjing Agriculture University.1 Hydroptila biuncialis Zhou et Yang, sp. nov.（Figs.1-5）This new species is somewhat close to species in Group H. sparsa, nevertheless the postero-lateral process of segment Ⅸ short and obtuse. It differs from all other species of this genus in tergum Ⅹ, hook-like, curved downward with its tip almost pointing frontward in lateral view. Holotype ♂,Jiangxi Province,Wuyishan National Nature Preserve,Litoujian Stream,100m upstream of protected area （27.99°N, 117.86°E） alt. 342m, 5 June 2005,coll. YANG Lian-Fang, C. J. Geraci. Etymology. The Latin word＂biuncialis＂means＂with two hooks＂, in reference to the posterior margin of segment Ⅹ divaricate to a pair of processes hook-like.2 Hydroptila leptocera Zhou et Yang, sp. nov.（Figs.6-11） This new species is somewhat close to species in Group H. sparsa, nevertheless the postero-lateral process of segment Ⅸ short and obtuse. It is very similar to previous new species Hydroptila biuncialis Zhou et Yang from Jiangxi in the shape of tergum Ⅹ, but differs in： 1） tergum Ⅹ broad at base, tappering gradually to narrow apex, with apico-lateral ends produced lateral-downward and each bearing two slender horn-like projections （broadest at middle portion, with its apico-lateral ends each bearing one long hook-like process in H. biuncialis）; 2） titillator circling the segment 1.5 times （titillator absent in H. biuncialis）.Holotype ♂, Guangxi Zhuang Autonomous Region, Shangsi City, Nalinhe, Trib of Mingjiang He, 2.0 km NW of main entrance to Shiwandashan National Forest Park （21°54′N, 107°53′E） alt. 281m, 5 June 2004, coll.
