As a result of processing the materials of Transcaucasian expedition concerning the Auchenorrhyncha of the Issidae family the author succeeded in finding out some rare, scantily investigated representatives and four species, new for science. Mycterodus lobatus sp. n. and M. mutuus sp. n. are similar to M. batumus Dlab. by the features of appearance and the structure of genitals. They form a group of species characterized by the presence of numerous developed laminar labella of the penis apex and its membrane. The third species of the genus M. alatus sp. n. is distinguished from the known reprebentatives by the presence of wings and comparatively simple, primitive structure of the penis. A new representative of the genus Conosimus — C. nuchensis sp. n. is close to C. goricus Dlab., but it is well distinguished from the latter by a series of external morphological features and peculiarities in the structure of male genitals.
