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.
