    Specimens of the North American leech, Placobdella ornata (Verrill, 1872) were confirmed from the Donkmeer, a freshwater lake in the
    province of East Flanders, Belgium, by morphological and molecular analysis. Leech specimens from Belgium were morphologically
    consistent with the syntype series and description of P. ornata by Verrill (1872). Molecular comparison of the Belgian specimens to
    specimens of P. ornata from the type locality (New Haven, Connecticut, USA) using the cytochrome c oxidase subunit I (COI) gene
    revealed a similarity of 99.5%. Placobdella ornata from Belgium is the first documentation of a second species of the genus Placobdella in
