The present paper reports two new species of the genus Trachytes,which is recorded for the first time to China. All type specimens are deposited in the National Base of Plague and Brucellosis Control,Baicheng City,Jilin,China.1 Trachytes jilinensis sp.nov. (Figs.1-9) ♀.Length 666-689*!μm,width 437-483*!μm.Film around anterior projection with stripes.Dorsum with 4 shields:one dorso-central,one pygidial and two marginal.Dorsal setae similar to willow leaf in shape,14 pairs on dorso-central shield and 3 pairs on pygidial shield,marginal setae arranged in a row along margin of body.Base of tritosternum rectangular,laciniae 4-branching.Sternal shield with 7 pairs of setae. Genital shield trapezoid-like,both anterior and posterior margins straight.Ventro-lateral shields with a seta respectively.Ventro-anal shield with 6 pairs of preanal setae and 5 perianal setae.Crack between sternal and ventro-anal shields X-shaped. The new species is similar to T.aegrota (Koch,1841),but differs from the latter in ventral cuticle without setae in X-like crack and preanal setae rank in regular order. Holotype ♀,paratypes 10♀♀ and 3 deutonymphs,collected from forest soils,in Shulan(44°25′N,126°57′E),Jilin Province, July 1994.2 Trachytes yinsuigongi sp.nov. (Figs.10-18) ♀.Length 747-781 μm,width 517-575 μm.Anterior film of body without stripe.Dorsal setae willow leaf-shaped,14 pairs on dorso-central shield and 3 pairs on pygidial shield,marginal setae arranged along margin of body,marginal shields with 4 setae near to row of marginal setae.Sternal shield with 6 pairs of setae.Ventro-anal shield with 7 pairs of preanal setae and 5 perianal setae.Crack between sternal and ventro-anal shields V-shaped. The new species is similar to T.eustructura Hirschmann et Z.-Nicol,1969,but differs from the latter in genital shield broader,ventro-lateral shields fused to ventro-anal shield and separated from sternal shield. Holotype ♀,paratypes 2♀♀,1 deutonymph and 2 protonymphs,collected from forest soils,in Shulan(44° 25’ N,126°57’E),Jilin Province,July 1994. The new species is named in honour of Prof.YIN Sui-Gong,famous acarologist of China.
