The genus Wernya Yoshimoto,1987 is reviewed from China.Two new species of Wernya are described,namely W.hamigigantea sp.nov.and W.cyrtoma sp.nov.W.griseochrysa is newly recorded from China by the description of a new subspecies W.griseochrysa hainanensis subsp.nov.The subspecies of W.thailandica Yoshimoto that distributed in China is revised.W.solena（Swinhoe） and W.punctata Yoshimoto are proved to be not distributed in China.A key to the Chinese species of Wernya,including 7 species and 2 subspecies,is provided.Wernya hamigigantea sp.nov.（Figs 1-2,7-8） Etymology.The specific name is from the Latin prefix ham-and giganteus,referring to the large hooked carina of the aedeagus.W.hamigigantea can be distinguished from other congeners by the much paler wing colour,and by having the oblique antemedial lines,with area between reddish brown.The most distinctive characters lie in the male genitalia having the stout and undivided socii,and the large hooked carina on the aedeagus.Holotype ♂,Hainan,Ledong,Jiangfengling,Mingfenggu,alt.983 m,6 Dec.2009,coll.YANG Chao.Paratypes：2♂♂,2♀♀,same data as holotype;6♂♂,5♀♀,Hainan,Jianfengling,Tianchi,alt.934 m,17 Dec.2007,coll.LI Jing;1♂,2♀♀,Hainan,Ledong,Jiangfengling,Tianchi,alt.982 m,23 to 26 Nov.2008,coll.LI Jing.Wernya griseochrysa hainanensis subsp.nov.（Figs 3-4,9-10） Etymology.The subspecific name is from the type locality name ＂Hainan Province＂.The main differences of W.griseochrysa from other congeners lie in the digitate uncus,short socii that are very close to the narrow base of the uncus,and the long spine-like lateral process of the transtilla.W.griseochrysa is close to W.hreblayi Laszlo,Ronkay,Ronkay et Witt,2007,but the latter lacks the distal triangular process at the middle of the valva,replacing with a slender spine under costa.Compared to the nominate subspecies,the male genitalia of W.griseochrysa hainanensis have blunter socii,smaller valva with narrower distal extending part and narrower and longer distal triangular process,and stouter aedeagus.Holotype ♂,Hainan,Bawangling,alt.1 015 m,19 Dec.2007,coll.LI Jing.Paratypes：1♂,same data as holotype;1♀,Hainan,Jianfengling,Tianchi,alt.934 m,14 Dec.2007,coll.LI Jing.Wernya cyrtoma sp.nov.（Figs 5-6,11-12,14） Etymology.The specific name is from the Latin etyma cyrtom-,which means curved and swollen,referring to the middle protrusion of the forewing postmedial line.W.cyrtoma is close to W.sechuana,but can be distinguished by the following characters.The forewing of W.cyrtoma is more caesious,and almost without reddish brown scales.The forewing postmedial line is distinctly approaching to wing base at the costa,and more protruding at middle than in W.sechuana.In the male genitalia,the uncus is broadly and shallowly concave and appearing as a V-shape in W.cyrtoma,but narrowly and deeply concave and showing a deep U-shape in W.sechuana（Figs 13,15） .Two branches of the saccus are much closer to each other in W.cyrtoma.In addition,the transtilla and juxta are different in these two species.Holotype ♂,Fujian,Mt.Wuyi,Sangang,alt.704 m,21 Oct.2005,coll.LANG Song-Yun.Paratypes：1♀,Fujian,Mt.Wuyi,Sangang,alt.704 m,31 July 2006,coll.XUE Da-Yong;1♀,Fujian,Mt.Wuyi,Guadun,alt.1 200 m,23 Oct.2005,coll.LANG Song-Yun.
