侧枝纹石蛾亚属中国种类记述(毛翅目:纹石蛾科:纹石蛾属)

Notes on the Subgenus Ceratopsyche (Trichoptera:Hydropsychidae: Hydropsyche) from China with Descriptions of Nine New Species

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 wings: 10 mm.Male genitalia of this species similar to that of Hydropsyche (Ceratopsyche) gautamiltra, but without lateral spines behind basal curve of phallobase, posterior processes of tenth tergum slender.Holotype (?) , allotype (?), paratypes 3 (?) (?), Hainan Island, 1984-Ⅵ-8, Li Youwen6. Hydropsyche (Ceratopsyche) tubulosa, sp. nov. (Fig. 3 D-H)Body length with fore wings: 12 mm.Male genitalia of this species very similar to that of Hydropsyche (Ceratopsyche) penicillata, but large endothecal processe inside penis with a big spine at tip; small lobe right behind phallotremal sclerites absent.Holotype (?) , paratype 1 (?), Anji, Zhejiang Province, 1987-Ⅴ-10, Zhou Wenbao.7. Hydropsyche (Ceratopsyche) trifora, sp. nov. (Fig. 4 A-C)Body length with fore wings: 10 mm.Related to Hydropsyche (Ceratopsyche) serpentina, but the upwards-curved spine of endothecal process equal to length of membranous part; downwards-curved posterior process of tenth tergum slender; one spine hidden in each of the three membranous holes of ventral endothecal lobe.Hololtype (?) , Huangshan, Anhui Province, 1984-Ⅶ-8, Hu Chunlin; paratypes: 1 (?) , Fanjingshan, Guizhou Province, 1984-Ⅶ-15, Li Youwen; 5 (?) (?) , Taibaishan, Shaanxi Province, 1983-Ⅷ-15, Taibaishan Ento. Exp. ;1 (?) , Tianmushan, Zhejiang Province, 1987-Ⅵ-25, Li Youwen.8. Hydropayche (Ceratopsyche) cerva, sp. nov. (Fig. 4 D - G)Body length with fore wings: 10 mm.Male genitalia of this species similar to that of Hydropsyche (Ceratopsyche) arden, but with a pair of short process like the horns of a fawn on the tenth tergum, penis expanded as a globe under phallotremal sclerites.Holotype (?) , para type 1 (?) , Xishuangbanna, Yunnan Province, 1982-Ⅳ23, Zhou Jingruo & Wang Sumei.9. Hydropsyche (Ceratopsyche) compressa, sp. nov. (Fig. 5 A-D)Body length with fore wings: 11 mm.Related to Hydropsyche (Ceratopsyche) columnata, but distinguishable by (1) narrow and trigonal posterior process of tenth tergum without any dorsal groove; (2) the ends of ventral endothecal process branc
