This paper deals with two species of the genus Blasiothrix collected from Henan, China. Among them, Blastothrix chinensis is described as new species and Blastothrix longipennis Howard is recorded for the first time from China. A key to 4 species is provided in the Chinese text.Blastothrix chinensis, sp. nov.This species resembles Blastothrix erythrostetha (Walker) and B. kermivora Ishii, but may be separated from the former by its scape 2.6 time as long as wide at the widest portion, and from the latter by its marginal vein much shorter than the postmarginal vein, approximately in the ratio of 5:9.Length of body: (?) 2mm; (?) 1.7mm.Holotype (?), allotype (?), paratypes 26(?), 13(?), Xinxian, Henan, 4, Ⅴ, 1981.All are reared by Shi Zhen-ya from adult females of Kermococcus nawae (Kuwana) and are deposited in the Department of Plant Protection, Henan Agricultural University, Zh-engzhou, China.
