Etude descriptive et cytotaxonomique d'une planaire polynésienne Dugesia tahitiensis n. Sp. [Turbellarié, Triclade]

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. © 1977 Masson.
