Pseudorhabdosynochus mizellei is a diplectanid monogenean parasitic on the gills of the red hind, Epinephelus guttatus.

According to Kritsky, Bakenhaster & Adams (2015), Pseudorhabdosynochus mizellei was named for the late Dr. John D. Mizelle, mentor of the senior author (Delane Kritsky) and codiscoverer of this new species in Bermuda, in recognition of his extensive research on Monogeneans occurring in North and South America.

According to Kritsky, Bakenhaster & Adams (2015), Pseudorhabdosynochus mizellei most closely resembles P. williamsi in the basic morphology of the vaginal sclerite and male copulatory organ.

P. mizellei is easily differentiated from P. williamsi by the deep root of the ventral anchor being shorter than the superficial root and the shaft of the dorsal anchor forming a gentle curve (vs dorsal-anchor shaft comparatively straight in P. williamsi).

[1] The type-host and only recorded host of P. mizellei is the red hind, Epinephelus guttatus (Serranidae: Epinephelinae).
