摘要：
The absence of significant distinctions between the species of the genus Planorbarius in the narrow sense (P corneus, P banaticus, P purpura, and P. grandis) has been established. All investigated species had identical chromosomal formulas (2n = 30m + 6sm = 36) and fundamental numbers (FN = 72). Reproducible distinctions between them were not found by total complement length (TCL), relative length of chromosomes (RL), and centromeric indexes. The species selected on the basis of genetic marking differed clearly by centromeric index of chromosome 12, which confirms the allospecies frame of Pcorneus s. lato.
