Abstract
Five new species of the genus Trechus Clairville, 1806 are described from the eastern part of the Tien Shan mountains (China, Xinjiang-Uygur Autonomous Region): T. tsanmensis sp. n. from the Narat Mountain Range, left bank of the Zanma River; T. torgaut sp. n. from the upper course of the Kunges River and Narat Mountain Range (both species belong to the uygur species group, which is defined here); T. aghiazicus sp. n. from the Aghiaz River and Koeksu Basin, T. cratocephalus sp. n. from the Narat Mountain Range (both belong to the micrangulus species group); and T. saluki sp. n. from the mountains S of the Kunges River (belonging to the kashensis species group, also defined in the present paper). Some new data on the distribution of T.uygur Deuve, 1993 and T. kashensis Belousov & Kabak, 2001 are given. The distribution of all known species of the uygur and kashensis groups is mapped. An identification key is provided to known species of the uygur group.
