In this paper sevennew species are described in four genera(Stactobiella,Ugandatrichia,Hydroptila,Orthotrichia)of Chinese Hydroptilidae,with two genera(Stactobiella,Ugandatrichia)of them new tocchinese fauna.These species areS.pulmonaria sp.nov u.naviculaisr.,H.acrodonta sp.nov.,H.cpinensis sp.nov.H.cochlearis sp.-nov.H.triangula sp.nov.,O.wellsae sp.nov.The type specimens are depoiseted in the Insect collection of Nanjing Agri-cultural University.1.Stactobiella pulomonaria sp.nov.(Fig.1)Male:Length of anterior wing 1.5mm.Antennae 18—segmented.Genitalia:In ventral view inferior appendages lunglobe—shaped,subgenital plate bell—sh-aped in caudal view.This new species is very similar to Chrysotrichia badhamiScpmid,but differs from it in that the spur formular 1,3,4 rather than 0,2,4,and the inferior appendage lunglobe—shaped.Types:Holotype ♂,Bawangling(320m),Hainan 25—IX—1988,collectedby Xue Yingen;Paratype:2 ♂ ♂.collected with holotype.2.Ugandatrichia navicularis sp.nov.(Fig.2)Male:Length of anterior wing 2.5mm.Antennae 28—segmented.Genitalia:Inferior appendage large,stout,with dorsal margin convex at basal 1/2 in la-teral view,its distal half tapering to a rounded apex.Subgenital plate broadat base,abruptly narrowing to tip,wirh apex hooked backward.This speciesvery close to nikatauwa(Schmid),but distinguishs from it by tergum 10 rec-tangular,inferior appendages without subapical processes.Types:Holotype ♂,Bawangling(320m),Hainan,25—IX—1988,collected by Xue Yingen.3.Hydroptila acrodonta sp.nov.(Fig.3)Male:Length of anterior wing 2.0mm.Antennae 31—segmented.Genitalia:Pleura IX produced posteriorly in a stout spine,inferior appendage slender,wi-th 3—4 spines on the apex dorso—laterally.this species is similiar to furcata(Martynov),from which it is distinguished by:inferior appendages with un-expanded ends,ventral plate of segment Ⅷ elongated to the middle of inferiorappendages.Types:holotype ♂,Bawangling(320m),Hainan,25—IX—1988.collectedby Xue Yingen;Paratypes:15♂♂,collected with holotype.4.HydroptilS chinensis sp.nov.(fig.4)Male.Length of anterior wing 2.2mm.Antennae 31—Segmented.This spec-ies is distinguished from pulchricornis pictet by each inferior appendage shout,with its under margin steight,upper margin slightly sinuate,and its apex witha acute hook upturned in right angle.Type:Holotype ♂,Wudalianchi,Heilongjiang,8—v111—1987.collected byxue Yingen.Paratypes:1 ♂,collected with holotype.5.Hydroptila cochlearis sp.nov.(Fig.5)Male:Length of anterior wing 2.5mm.Antennae 32—segmented.This sp-ecies stands apart from other species in having:tergum X broadly fruncate,with two spines on it lower angle in lateral view,inferior appendages spoon—shaped in ventral view.Type:Holotype ♂,Linxian Qihe,Henan,27—Ⅷ—1988.collected by XueYingen.Paratypes:1 ♂,collected with holotype.6.Hydroptila triangula sp.nov.(Fig.6)Male:Length of anterior wing 3.0mm.Antennae 33—segmented.Genitalia:Posterior side pieces of segment IX strongly projecting backward reaching about3/4 length of inferior appendage from its base,inferior appendage subtriangu-lar,with apex hooked turning down—outward.This species is different fromother species in having:inferioor appendages trangular,segment IX with long,broad posterior side pieces,aedeagus with willow—leaf—shaped titillator andthe middle bearing internal spire.Types:holotype ♂,Linxian Qihe,Henan.27—Ⅷ—1988,collected by XueYingen7.Orthotrichia wellsae sp.nov.(Fig.7)Male:Length of anterior wing 2.0mm.Antennae 22—24—segmented.Geni- talia:tergum X hood—like,its right dorsal spine bi—forked,directed to leftand its left sub—distal spine bi—forked,directed to rihgt with the lower oneturn to down—backward.Inferior appendages asymmetrical,left one curveddistally,right one triangular in ventral view.This species is similiar to hin-ipitigola(Schmid),from which it is distinguished by the well developed rightdorsal spine and subapical spine,and the anterior margin of tergum 1x projec-ting forward nearly in square plate.Types:Holotype ♂,Longsheng(320m),Guangxi 20—IX—1988,collectedby Xue Yingen.Paratypes:3 ♂ ♂,collected with holotype.
