Boophthora erythrocephala is a widely spread species inhabiting both small polluted water-bodies and large
rivers. Three populations from Samara region in Russia and from Donetsk and Chernigov regions in the
Ukraine have been studied. Five populations of this species in Russia were described earlier (Polyanskaya, Tsapygina,
1968; Petrukhina, 1972). For identification of this species the chromosome map of Adler and Werner
(personal communication) was used. Comparison of 8 populations studied was performed. All of them belong to
the species Â. erythrocephala but everyone has its own individual characteristics. Inversion polymorphism was
observed in each population comprising from 88 to 100 %. Mean number of heterozygous inversions per individual
is low fluctuating around 3.6. There is one inversion in IIS observed in all populations that proves panmixy
among them. Other inversions occur in a part of the individuals.
