dc.description.abstract Comparative phylogeography has become a powerful approach in exploring hidden or cryptic diversity within widespread species and understanding how historical and biogeographical factors shape the modern patterns of their distribution. Most comparative phylogeographic studies so far focus on terrestrial and vertebrate taxa, while aquatic invertebrates (and especially freshwater invertebrates) remain unstudied. In this article, we explore and compare the patterns of molecular diversity and phylogeographic structure of four widespread freshwater copepod crustaceans in European water bodies: the harpacticoids <i>Attheyella crassa, Canthocamptus staphylinus</i> and <i>Nitokra hibernica</i>, and the cyclopoid <i>Eucyclops serrulatus,</i> using sequence data from mtDNA COI and nuclear ITS/18S rRNA genes. The three taxa <i>A. crassa</i>, <i>C. staphylinus</i> and <i>E. serrulatus</i> each consist of deeply diverged clusters and are deemed to represent complexes of species with largely (but not completely) non-overlapping distributions, while in <i>N. hibernica</i> only little differentiation was found, which may however reflect the geographically more restricted sampling. However, the geographical patterns of subdivision differ. The divisions in <i>A. crassa</i> and <i>E. serrulatus</i> follow an east–west pattern in Northern Europe whereas that in <i>C. staphylinus</i> has more of a north–south pattern, with a distinct Fennoscandian clade. The deep mitochondrial splits among populations of <i>A. crassa</i>, <i>C. staphylinus</i> and <i>E. serrulatus</i> (model-corrected distances 26–36%) suggest that divergence of the lineages predate the Pleistocene glaciations. This study provides an insight into cryptic diversity and biogeographic distribution of freshwater copepods.
