The prsent paper deals with the Chinese genus Shivaphis Das, 1918,which consists of 3 species. Among them,Shivaphis similicelti Zhang, W.Y and G.X.Zhang is a new species and Shivaphis szelegiewiczi Quednau, 1979 is recorded from China for the first time. The key to the chinese species is given. The specimens including the types are deposited in the institute of Zoology,Academia Sinica. Abbreviations used in this paper are as follows: u.r.s.stands for ultimate rostral segment;ht Ⅱ stands for 2nd hind tarsal joint.
