Fauna, features of ecology and karyotypes of non-biting midges from genus Chironomus meigen, 1803 (Diptera, Chironomidae) at temporary reservoirs in Sukanskiy gorge (Central Caucasus)

Data on fauna, features of ecology and karyotypes of non-biting midges from genus Chironomus Meigen, 1803 (Diptera, Chironomidae) at temporary reservoirs of upper courses of Sukanskiy gorge (Central Caucasus, northern macroslope) are submitted. Three species of chironomus are found: Chironomus : Ch. piger Strenzke, 1959, Ch. dorsalis Meigen, 1818 и Ch. riparius Meigen, 1804. All species are widespread and typical inhabitants of temporary reservoirs. Chromosomal reorganizations it is not revealed. Chromosomal monomorphism of Ch. piger, Ch. dorsalis и Ch. riparius can testify to their dwelling in the territory of Sukanskiy gorge only in this type of the reservoirs, being characterized rather constant parameters. Features of biotopical placement of the found species in concept of living in temporary reservoirs chironomids biotic strategy are considered.
