Variability of the dimensional structure in the hemipopulation of Thominx neopulchra (Nematoda: Capillariidae) females from bats of the genus myotis (Chiroptera: Vespertilionidae)

Variability of the dimensional structure in the hemipopulation Thominx neopulchra females from 3 species of the genus Myotis bats in the Zhiguli State Reserve was examined. The size of T. neopulchra from different bat species varied within the limits constituting 10.17-13.41 mm. It was demonstrated that the variability of the dimensional structure in the subpopulation group T. neopulchra from Daubenton's bats did not depend on the number of parasites in the host and the season and is probably determined by the genetic polymorphism of the parasite population.
