Two new freshwater triclad species of the genus Dugesia Girard, 1850 are described from the oriental region. The first is the only species of freshwater triclad described from Ceylon and the second, a cavernicolous form, is the only one known from Malaya. A synopsis, in tabular form, of the oriental Dugesia species is also given and some aspects of their distribution are discussed. It is intended that the tabular synopsis should provide diagnostic characters for the delimitation of the new and previously described species, and act as a basis for a future revision of the oriental representatives of the genus, many of which are poorly described or poorly known. Apreliminary dichotomous key to the valid species is also provided.

There seems little doubt on morphological grounds of the close relationship between the Planariidae and the Dendrocoelidae but it is difficult to connect, phylogenetically, the Dugesiidae with these groups. A connection between the former and some of the latter has been unknowingly implied by the author in previous papers, thus raising an anomaly since this would mean that the Dugesiidae are not monophyletic. Is it possible that the Dugesiidae and the Planariidae + Dendrocoelidae have arisen independently from marine ancestors?

The ten species of freshwater planarians known from Victoria, including one new species, are briefly reviewed. Detailed field and laboratory studies of six of these have been made and a close correlation between seasonal variation in numbers and viability at different laboratory temperatures is demonstrated. Thus Spathula camara and Reynoldsonia reynoldsoni inhabit temporary habitats that experience wide temperature fluctuations and these two species survive equally well in the laboratory at a wide range of temperatures. In contrast Spathula tryssa appears stenothermal in habitat and in the laboratory cannot tolerate even a small temperature increase. Cura pinguis and Dugesia (Girardia) sp. also show wide temperature tolerance both in terms of abundance in the field and viability studies in the laboratory. Spathula agelaea sp. nov. is unusual in that it shows two annual peaks in abundance and also exhibits aggregatory and cannibalistic behaviour that may be involved in population regulation. Aspects of the distribution, abundance, and life cycle, of all the species are discussed in relation to what is known generally of planarian ecology.
