Abstract

Geographical distribution in Sardinia of different karyological biotypes ofDugesia (Schmidtea)polychroaandDugesia(S.)mediterraneahas been investigated.On the whole, 4 biotypes ofDugesia(S.)Polychroa(A, C. D, and A pentaploid biotypes) and 2 biotypes ofDugesia(S.)mediterranea(G, and G triploid biotypes) have been recorded. The A pentaploid and G triploid biotypes were never found in Sardinia before now.We wish to underline i) the fìnding, in the Temo river, of 5 different biotypes: C, D, A pentaploid ofDugesia(S.)polychroaand G, G triploid ofDugesia(S.)mediterranea; ii) no biotypes ofDugesia(S.)polychroaorDugesia(S.)mediterranea, up to date, have been found by us in the oriental catchment areas of Sardinia.
