A list of 145 species of the family Tortricidae, recorded from the western part of Tuva, is presented. The material studied originates from a joint FinnishRussian expedition made in June 1995. Additional data have been taken from Ukrainian, Russian and German literature. Cochylimorpha arenosana n. sp. from sand dunes of Northern Mongolia is described. Three species, Falseuncaria lechriotoma Razowski, 1970, Acleris idonea Razowski, 1972 and Eucosma argentifera Razowski, 1972 - all described from Mongolia - are reported as new for Russia. From the total of 145 species 138 can be placed into three main zoogeographical complexes: Holarctic/Palaearctic about 83%, Mediterranean- Central-Asiatic about 10% and endemic for the mountains of CentralAsia about 7%. The Holarctic complex can be divided into four chorological groups: Holarctic (22 spp.), Transpalaearctic (65 spp.), Western Palaearctic (12 spp.) and Eastern Palaearctic (13 spp.). Subalpine meadows and grazed steppes of Mongun-Taiga and the Tannu-Ola Mnts. are inhabited by some endemics of the Central-Asian mountains (11 spp.).
