Two new Ptychoptera Meigen, 1803 (Diptera, Ptychopteridae) from the Western Palaearctic.

Ptychoptera xanthopleura Dvořák, Oboňa & Manko, sp. nov. from Azerbaijan and Georgia, and Ptychoptera staryi Dvořák, Oboňa & Manko, sp. nov. from Bulgaria are described. P. xanthopleura sp. nov. differs from the other member of the lacustris group mainly by having almost completely yellow pleurae, and by the shape of the epandrium and gonocoxites. The diagnostics of P. staryi sp. nov. and P. incognita Török, Kolcsár & Keresztes, 2015 based on male genitalia are provided. [ABSTRACT FROM AUTHOR]
