	abstract = {<p>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.</p>

	abstract = {<p>To determine whether the Lake Ohrid population of Dendrocoelum lacteum is significantly genetically distant from the Central European populations of this species, the allozyme variation was studied. Phylogenetic analysis of isozyme electrophoretic data indicated that the D. lacteum populations from Central Europe exhibit a closer relationship to Dendrocoelum adenodactylosum from Lake Ohrid (used as a reference species) than to their conspecific population from this lake. The allozyme data support the suggestion that D. lacteum from Lake Ohrid could be classified as a distinct species.</p>
