''Pseudorhabdosynochus williamsi'' is a diplectanid monogenean parasitic on the gills of the Rock hind, ''Epinephelus adscensionis''. It has been described by Kritsky, Bakenhaster and Adams in 2015. 〔 〕 ==Description== ''Pseudorhabdosynochus williamsi'' is a small monogenean, half a millimetre in length. The species has the general characteristics of other species of ''Pseudorhabdosynochus'', with a flat body and a posterior haptor, which is the organ by which the monogenean attaches itself to the gill of is host. The haptor bears two squamodiscs, one ventral and one dorsal. The sclerotized male copulatory organ, or "quadriloculate organ", has the shape of a bean with four internal chambers, as in other species of ''Pseudorhabdosynochus''.〔Kritsky, D.

Proceedings of the Biological Society of Washington, 99, 17-20.
