摘　　要：H.H.Ross和John D.Unzicker于1977年将纹石蛾属Branta组的种类建立一个新亚属——侧枝纹石蛾亚属Ceratopsyche,并移入Symphitopsyche属。A.Nielsen(1981)进一步将其提升为属。而P.W.Schefter等(1986)认为仍作为纹石蛾属的亚属较为适当。此亚属均分布于北半球,其中新北区30种,印度——马来区3种,古北区35种。中国目前已知9种,本文又发现9新种和3新记录种。中国种类的雄成虫检索表和新种、新记录种的描述如后。新种模式标本保存于南京农业大学植保系。In this paper a key to male adults of 21 species of the subgenus Ceratopsyche from China is given. Among them 3 species are reported as new records to China and 9 species are described as new to science. The type specimens are deposited in the Department of Plant Protection, Nanjing Agricultural University.1. Hydropsyche (Ceratopsyche) tetrachotoma, sp. nov. (Fig. 1 A-D)Body length with fore wings: 9 mm.Male genitalia much like that of Hydropsyche (Ceratopsyche) bryanti Bands, but its endothecal process long and slender; posterior process of tenth tergum short, broad and straight with a dorsal groove.Holotype S , Huaping, Guangxi, 1984-Ⅶ-7, Li Youwen.2. Hydropsyche (Ceratopsyche) lianchiensis, sp. nov. (Fig. 1 E-H)Body length with fore wings: 12.0-12.5 mm.Male genitalia of this species rather peculiar for a pair of narrow, twisted sclerites, sharp at apex, under endothecal processes; membranous endothecal process thick and short, tipped with a pin; back of penis apex membranous.Holotype (?) , Wudalianchi, Heilongjiang Province. 1987-Ⅶ-8, Xue Yingen. Paratypes 2 (?) (?) and a series of (?) (?), same data as hiolotype.3. Hydropsyche (Ceratopsyche)curvativa, sp. nov (Fig. (?)(?) D)Body length with fore wings: 11 mm.Male genitalia similar to that of Hydropsyche (Ceratopsyche) fukiensis, but can be distinguished by a pair of up-turned membranous processes on apex of penis, U-shaped membranous area at the back of the apex, and slightly flattened harpago.Holotype (?) , Anji, Zhejiang Province, 1987-Ⅴ-13, Zhou Wenbao.4. Hydropsyche (Ceratopsyche) conoidea, sp. nov. (Fig. 2 E-I)Body length with fore wings: 9 mm.Male genitalia of this species similar to that of Hydropsyche (Ceratopsyche) fukiensis, but without small median membranous process between two lateral lobelets of the ventral endothecal lobe, with a dorsal button-like membranous spot behind phallotremal sclerites.Holotype (?) , Miaoershan, Guangxi, 1984-Ⅶ-10, Li Youwen.5. Hydropsyche (Ceratopsyche) hainanensis, sp. nov. (Fig. 3 A-C)Body length with fore wi
