Sluys R, Kawakatsu M, Winsor L (1998) The genus Dugesia in Australia, with its phylogenetic analysis and historical biogeoraphy (Platyhelminthes, Tricladida, Dugesiidae). Zool Scripta 27: 273-289 |
Abstract / Notes
"The new species Dugesia notogaea Sluys and 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."
