The karyotype analysis of the Glyptotendipes paripes Edwards, 1929 from water reservoirs of Saratov region has been conducted. In the studied population,
the following combination of banding sequences predominated: A1.1, B1.1 and G1.1. The frequency of larvae with heterozygous inversions was 72.9 %, the average number of
heterozygous inversions per specimen was 0.667, and the most frequent heterozygous inversions were B1.2 (39.5 %) and D1.2 (29.2 %). Localization of centromeres in the
polytene chromosomes G. paripes was defined with the help of C-banding. Homoeology of polytene chromosomes of two chironomidae species (G. paripes and
G. glaucus Mg.) has been analyzed and redesignation of chromosomes arms G. paripes has been offered: instead of par D - par A, instead of
par C - par B, instead of par A - par D and instead of par B - par C.
Key words: Glyptotendipes, polytene chromosomes, homoeology, chromosome polymorphism
