Chartoscirta elegantula longicornis (Jakovlev, 1882)

Material examined. BULGARIA: Burgas: Burgas, Atanasovsko ezero Lake, shore, 18. vii.1976, 1 ♀, K. Hůrka lgt., P. Kment det. (NMPC). GEORGIA: Abkhasia: Inkit Lake, 6.–17. vi.1969, 2 ♀, J. Dezort lgt., J. L. Stehlík & P. Kment det. (MMBC).

Distribution. This subspecies is recorded from Serbia, Bulgaria, Ukraine, Russia (South European Territory), Georgia, Armenia, Azerbaijan, Iraq, Iran, and Turkmenistan (Lindskog 1995, Linnavuori & Hosseini 2000, Protić 2009, Aukema et al. 2013). The co-occurrence of both Ch. e. elegantula and Ch. e. longicornis at the locality Atanasovsko ezero on Black Sea Coast of Bulgaria is remarkable, emphasizing the uncertain subspecies status of the both taxa.
