In the present paper 7 species of Smidtia from China are studied,among which, three are described as new to science. A key to the 7 species is also given. 1 Smidtia longicauda sp. nov.(Fig.1);This species is similar to S. amoena in having dense hairs on parafacialia descending to the level of the first facial bristle; frons narrow, not wider th an 1/4 of eye width, differing primarily in unusually long and thin cerci, whic h can be distinguished from all partners of this genus. Body length: 11-14?mm. Holotype ♂, Liaoyuan (42°9′N, 125°1′E), Jilin Province, 28 June 1982, by WU Xiu-Lian; paratypes 56♂♂, 6♀♀, Liaoyuan, Jilin Province, 4 May-6 June 1982,by WU Xiu-Lian and DONG Zhi. 2 Smidtia candida sp. nov.(Fig.2);This species is similar to S. japonica in that the frons about 1/2 times of eye-width; hairs on parafacialia are sparse and not distributed below the firs t frontal bristle; first flagellomere 1.5 times as long as pedicel. It is easil y distinguished from the latter by the shape of the cerci and surstyli. Body length: 11?mm. Holotype ♂, Yichun (47°7 N, 128°9 E), Heilongjiang Province, 22 May 1962.3 Smidtia yichunensis sp. nov. (Fig.3);This species is similar in general appearance to S. amoena, but is distingu ished from the latter by hairs just below the first frontal bristle being small and sparse; frons wider, 2/7 times of eye width; frontal bristles stronger and more sparse; parafrontalia almost bare, with only several short hairs; cerci an d surstyli are more narrow and straight; black or dark brown long hairs behind t he row of anepisternal bristles are not or slightly frizzled apically. Body length 10?mm. Holotype ♂, Yichun (47°7 N, 128°9 E), Heilongjiang Province , 2 June 1959.
