Pseudorhabdosynochus jeanloui is a diplectanid monogenean parasitic on the gills of the Pacific creolefish, "Paranthias colonus" (Perciformes, Serranidae). It has been described in 2015 by Knoff, Cohen, Cárdenas, Cárdenas-Callirgos & Gomes.
Description.
"Pseudorhabdosynochus jeanloui" is a small monogenean, 0.6-0.0 mm 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".
The vagina includes a sclerotized part, which is a complex structure.
