Six new species of Hydropsychidae from China are described.8 paratypes ofHerbertorossia quadrata are deposited in the Department of Zoology,Hongkong Uni-versity.Other type specimens are deposited in the Department of Plant Protection,Nanjing Agricultural University.1.Hydromanicus fissus,sp.nov.(figl.1～4)This species can be separated from Hyromanicus intermedius Martynov by:(1)thetip of coxopodite oblique slightly,(2)without lateral process of phallotremal sclerite.(3)length of its body two times that of the latter.Holotype(?),Emeishan,Sichuan Province,600m,1957-IV-23,Zhen Leyi,etc.2.Hydromanicus canaliculatus,sp.nov.(figl,5～9)This species is resembling Hydromanicus intermedius Martynov,but differs fromthe latter in the apex of ventral endothecal process expanded as a spoon;concave athind margin of the tenth tergum as long as the length of 1/4 of the tergum.Holotype♂,allotype♀,paratype:14♂♂,Wuyishan,Fujian Province,1983-Ⅷ-1,Li Youwen.3.Hydromanicus emeiensis,sp.nov.(fig 2,1～5)This species differs from Hydromanicus intermedius Martynov in the sharp,curvedinward ventral endothecal proccss.Holotype♂,Emeishan,Sichuan Province,1984-Ⅷ-27,Li Youwen.4.Hydromanicus guangdongensis,sp.nov.(fig 2,6～9)This species is like Hydromanicus frater Ulmer,but can be distinguished by:(1)itsshort ear like preanal appendage,(2)the harpago long and slender,(3)the apex ofphallobase expanded abruptly.Holotype♂,allotype♀,Tianchi,Jianfeng Mountain,Hainan Island,1982-Ⅶ-6-22,Hua Lizhong,ect;paratype 1♀,Sanfenchang,Jianfeng Mountain,Hainan Island,1982-Ⅷ-31,Liang Chengfeng.5.Hydatomanicus ovatus,sp.nov.(fig 3,1～4)This species is allied to Hydatomanicus verrocosus Ulmer.The main defferences be-tween them are hind margin of the tenth tergum concave fissure-like at middle,notarc-shaped as in the tergum.Holotype♂,Wuhua County,Guangdong Province,1978-Ⅵ-25, Liang Meifang,6.Herbertorossia quadrata,Li et Dudgeon sp.nov.(fig 3,5～9)Length of the fifth segment is longer than that of the third and the fourth segmenttogether.But according to the characters such as venation of wings,tarsal claws of forelegs,formula of tibial spurs and male genitalia this species belongs to genusHerbertorossia.Male genitalia of this species is like that of Hydropsyche obscura Martynov,but canbe distinguished by the squarc hind-lateral process of the ninth segment and squareendothecal process;harpago short,equal 1/4 of coxopodite at apex.Holotype♂,allotype♀,Paratype 1♀,Chenzhou,Hunan Province,1985-Ⅷ-3, Zhang Yaling,ect;5♀♀,3♀♀,Hongkong,1987-Ⅶ-27,David DudReon.
