Six endemic and two widely distributed species living in Lake Ohrid were studied. In general, these hermaphroditic animals displayed no signs of departure from Hardy-Weinberg equilibrium. Genetic variation in all but one of the endemic species was of the same extent as that in geographically wide ranging invertebrates. On the other hand, the Lake Ohrid population of the common European species Dendrocoelum lacteum was monomorphic at all loci examined. D. sanctinaumi, one of the endemic species, exhibited a clear genetic subdivision into spring and littoral subpopulations. The genetic differentiation of Crenobia alpina alpina and C. a. montenigrina proved commensurable to that of well separated species from other genera. The data suggest that the separation of particular lineages in the set of Lake Ohrid endemics was widely dispersed over time.
