The examination of gill parasites from Pangasius polyuranodon Bleeker, 1852 (Siluriformes, Pangasiidae) in Indonesia revealed the presence of a new species of Manogenea, belonging to a new genus: Pangasitrema camillae n. g., n. sp. (Ancylodiscoididae). Among Ancylodiscoididae, the genus has several distinguishing features: the reduced size of the haptor, the morphology and size of gripi, the absence of a ventral transversal bar and of a cuneus associated with dorsal gripi.
