A list of the 18 species of Limoniid-flies collected on the Zailijsky Alatau (Kazekh SSR) and Kungey Alatau (Kirghiz SSR) mountain ridges of the northern Tien Shan is given. Two species, Ormosia (s. str.) helifera Sav. and Gonomyia (s. str.) sexlobata Sav., are described as new for the science. They differ from the all allied species of the genus in the details of the male hypopyg structure. The typical specimens of both are preserved in the collection of the Institute of Zoology, Kiev.
