Pseudorhabdosynochus cyanopodus is a species of diplectanid monogenean that is parasitic on the gills of the blue grouper Epinephelus cyanopodus. It was described in 2008.^[1]

Description

Pseudorhabdosynochus cyanopodus is a small monogenean, 300–700 μm 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.^[2]

The vagina includes a sclerotized part, which is a complex structure.^[1]

Etymology

The name of the species cyanopodus was given in reference to the name of the host, Epinephelus cyanopodus.^[1]

Hosts and localities

The type-host and only recorded host of P. cyanopodus is the blue grouper Epinephelus cyanopodus (Serranidae: Epinephelinae). The type-locality and only recorded locality is off Nouméa, New Caledonia. This grouper also harbours several other species of Pseudorhabdosynochus, namely P. chauveti, P. podocyanus, P. exoticus, P. duitoe, and P. huitoe, and a diplectanid belonging to a different genus, Laticola cyanus.^[1] On the specimens of fish from off New Caledonia examined, P. chauveti represented 9% of the total number of monogeneans on the gills; 141 specimens were examined.^[1]
