Girardia tigrina ( Girard, 1850)

Among Dugesiidae the allochthonous American species Girardia tigrina , introduced into Europe in the first half of the last century, was recently found in the Rio Cuga basin in the northwestern part of the island, representing the

first record for Sardinia ( Fig. 2 ). The population is characterized by only fissiparous individuals. At the same sampling site of these G. tigrina animals specimens of S. mediterranea were also found ( Fig. 2 ).
