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.
