Prochristianella aciculata n. sp. and P. omunae n. sp. (Platyhelminthes, Cestoda, Trypanorhyncha, Eutetrarhynchidae) are described from the spiral valve of Neotrygon kuhlii (Müller & Henle, 1841) (Rajiformes, Dasyatidae) from Nouméa, New Caledonia, representing the first records of this cestode genus from the southern Pacific Ocean. Prochristianella aciculata n. sp. is distinguished from congeners by aciculate hooks in the principal rows of the metabasal tentacular armature and by the unique morphology of the first hooks in each row. Prochristianella omunae n. sp. is distinguished from congeners by its extended basal armature (20 rows of hooks) and the presence of enlarged hooks at the very base of the tentacle.


Platyhelminthes, Cestoda, Trypanorhyncha, Prochristianella, New Caledonia, new species.
