A new species of the genus Dugesia (Turbellaria, Tricladida, Paludicola) from Tham Kubio Cave, Khon Khaen Province, Thailand, is described: Dugesia deharvengi Kawakatsu et Mitchell, sp. nov. The present new species is a true troglobite, completely lacking body pigmentation and eyes. D. deharvengi can be separated easily from the other members of the genus in its external morphology and in the details of genital anatomy and histology.

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.
