A Trichoptera list compiled for the first time for the Saur and Tarbagatai Mountains, northeastern Kazakhstan, comprises 38 species of 24 genera in 13 families. The region is notable as a contact zone for Siberian, Boreal, and Central Asian Trichoptera faunas. The study reveals numerous limits of distribution for species comprising more than half of the local fauna at very low level of local endemism. The fauna is poor and probably resulted from post-glacial colonization through some zoogeographic barriers.
