KONSTANTINOV1 ABSTRACT Key, descriptions, data on distribution and host plants are given for species of Camptotylus Fieber, including two new ones: Camptotylus apanaskevichi, n. sp. (Armenia, Uzbekistan, Tajikistan,and Mongolia)and Camptotylus reaumuriae,n. sp. (Mongolia). INTRODUCTION were found in the course of the present study. A key to both sexes of all species is provided.
