Four new species of the subgenus Dugesia from the Mediterranean region and the Middle East are described: D. liguriensis from northern Italy, D. arcadia from the Peloponnesos (Greece), D. vestibularis (=D. cretica form C) from Iran and D. nansheae from Iraq. D. arcadia is closely related to D. minotauros and D. iranica while D. nansheae shows affinities with the oriental species of the subgenus. The distributional ranges of two known species are extended: D. minotauros, from Crete, is newly recorded from the Peloponnesos (Greece) and D. iranica, known from Iran and the Kopet-Dag region in the Soviet Union, is newly recorded from Turkey. With the reassessment of D. cretica, records of its occurrence in the Peloponnesos, Turkey, Iran and Israel are invalidated. D. cretica is known with certainty only from the Mediterranean islands of Crete, Tinos, S\érifos and Cyprus, and also from Romania.

The new species Dugesia notogaea Sluys \& Kawakatsu, sp. n. is described from Queensland, Australia, representing the first record of the genus Dugesia for that continent. A phylogenetic analysis of the 68 species of Dugesia resulted in the discovery of a new apomorphy for the genus, and a cladogram showing two major phyletic groups. The distributional range of one group has a western accent, whereas that of the other group has an eastern emphasis; the ranges of these two groups overlap in Africa and the Mediterranean region. We attempt to determine the ancestral area for both the Dugesiidae and Dugesia. A scenario for the historical biogeography of the genus Dugesia is discussed. In this scenario it is presumed that the geological history of the Australasian region enabled Dugesia\’s from southeast Asia to colonize northern Australia.
