Abstract

The presence of the stenothermic cold-water planarian Crenobia alpina (Dana) has been evidenced in Sardinia for the first time. Identification of the freshwater species was made on the basis of its physio1ogical and morpho-anatomical characteristics.Furthermore the cytological data demonstrated that this population presents a polyploid karyotype with a marked tendency to aneuploidy.
The specimens were collected from three sites in the Gennargentu mountains as well as from a fourth at «Funtana Bona» near Orgosolo.
The finding of Crenobia alpina in Sardinia shows that the distribution of this species extends further south within the Mediterranean area than previous reports would suggest.
