Data about the karyotype characteristics, features of chromosomal polymorphism and larval morphology of populations of    Chironomus   bernensis    Wülker &amp; Klötzli, 1973 (  Diptera  ,   Chironomidae  ) from the Central Caucasus (the northern macroslope) and Ciscaucasia are presented. The characteristics of the pericentromeric regions of the long chromosomes of this species from Caucasian populations were very similar to the ones from some European populations (from Poland and Italy), but differed from Swiss and Siberian populations. In the North Caucasian populations 10 banding sequences were found: two in arms A, C, and E, and one in arms B, D, F, and G. Nine of them were already known for this species, and one, berC2, is described for the first time. Cytogenetic distances between all the studied populations of    Ch.   bernensis    show that close geographical location of all studied populations from the Central Caucasus and Ciscaucasia is reflected in their similar cytogenetic structure, but on the other hand, that they are more closely related to populations from Europe than to populations from Western Siberia. At the same time, all studied larvae from Caucasian populations have a four-bladed premandible, instead of a two-bladed one, as in the description of    Ch.   bernensis    from Switzerland ( Wülker and Klötzli 1973 ,  Polukonova 2005c ). These peculiarities may indicate the relative isolation of the Caucasus from the viewpoint of microevolution. Further research on karyological and morphological characteristics of    Chironomus   bernensis    from geographically distant regions is necessary as there is a possibility that the presently known species is actually polytypic and consists of several sibling species.
