TABLE 2. — Polymorphism and selection in populations of Helobdella stagnalis (Linnaeus, 1758), Glossiphonia concolor (Apathy, 1888) sensu lato, Alboglossiphonia hyalina (Müller, 1774), and A. weberi (Blanchard, 1897): Hd, haplotype diversity; π, nucleotide diversity; dN and dS, the numbers of synonymous and nonsynonymous substitutions per site,respectively;Tajima’s D, a test statistic of neutrality. P -values less than 0.05 do not support the null hypothesis of neutrality.
