Petrova N.A., Zhirov S.V.
Abstract. Polytene chromosomes of chironomid larvae (Diptera: Chironomidae), collected on the Wrangel Island are described. Larvae have 2n=8: AB, CD, EF, G (Ch. thummi Keyl, 1962 complex). By karyotype larvae are identical to Chironomus sp. Le1, described from the Sagystyr Island of the Ust-Lena Reserve (Yakutia) (Kiknadze et al., 1996). The insignificant differences include the number of nucleoli and puffs, which is regarded as a result of habitation of populations under different ecological conditions.
