L'ordre des Triclades est signalé pour la première fois en Polynésie. Dugesia tahitiensis n. sp. (Paludicole, Dugesiidae) présente les caractères morphologiques du sous-genre Girardia ; son caryotype, à 2 n = 16, se rapproche également de celui de ces formes. Il s'agit sans équivoque d'une espèce très primitive, asexuée typique, qui se reproduit uniquement par scissiparité.
Abstract
The order Tricladida is recorded for the first time in Polynesia D. tahitiensis (Paludicola, Dugesiidae). Shows the morphological features found in the subgenus Girardia ; its caryotype 2 n = 16 is closely related to those of its forms. Undoubtedly this species can be considered as a very primitive, with typical asexual reproduction by scissiparity.
