Type locality Several localities listed (probably all in Fergana valley), it's not clear which of those is the type locality: "r. Karakul'dzha ur. Kochkar-Ata (?), g. Dzhalbars-Mazar, gory Aldiyar i Chigirchik, rr. Tar (?) i Kurshab, g. Isfara; Kazakhstan (rayon Atabaya)" [river Karakul'dzha ur. Kochkar-Ata (?), Dzhalbars-Mazar, Aldiyar and Chigirchik mountains, rivers Tar (?) and Kurshab, Isfara; Kazakhstan (Atabay region)]. The figured specimen (perhaps the holotype) comes from river Karakul'dzha. [details]
