A cytophotomap of C. pallidivittatus salivary gland polytene chromosomes is presented. The pattern of C. tentons polytene chromosome banding was used as a standard to map C. pallidivittatus polytene chromosomes and to show the fixed inversions participating in karyotype divergence of these sibling species. C. pallidivittatus forth instar larvae were collected in nine Siberian localities. Chromosomal polymorphism was studied in four natural populations. Twenty four inversion sequences and 30 genotypic combinations of these sequences were identified. Nine new inversion sequences were described. The sibling species of C. tentons lias 42 inversion sequences and 63 genotypic combinations. Only 5 chromosome arms are polymorphic in Palearctic C. pallidivittatiis. Palearctic C. tentans has all 7 polymorphic chromosome arms.
