Pseudorhabdosynochus justinei is a species of diplectanid monogenean that is parasitic on the gills of the longfin grouper Epinephelus quoyanus. It was described in 2007 by Binjian Zeng and Tingbao Yang from material from the South China Sea,[1] and redescribed in 2009 by Justine, Dupoux & Cribb from material from off Queensland, Australia.[2]
Pseudorhabdosynochus justinei is a small monogenean, 0.3-0.5 mm in length.[1] 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.[3]
The vagina includes a sclerotized part, which is a complex structure. The authors of the species found that Pseudorhabdosynochus caledonicus Justine, 2005 was the closest species in term of vaginal structure.[1]
