Pseudorhabdosynochus manifestus is a diplectanid monogenean parasite first found in host Epinephelus malabaricus near Nouméa, between its secondary gill lamellae.

It was ascribed that name because it was the most abundant species found while its descriptive study was taking place.

At the same time, the former do not show a distinctive ring in the posterior part of the primary canal, while the shape of their chambers is different as well.

The haptor is differentiated from its body, being less wide (about 220 μm), and exhibits 2 round squamodiscs, 2 pairs of lateral hamuli, 3 bars and 14 hooklets.

It counts with an unsclerotised, dorsally question mark-shaped vagina that is elongate; its total length is about 35 μm.
