Pseudorhabdosynochus capurroi is a diplectanid monogenean parasitic on the gills of the Black grouper, Mycteroperca bonaci.

It was described by Vidal-Martínez and Mendoza-Franco in 1998[1] and redescribed successively by Yang, Gibson and Zeng in 2005[2] and by Kritsky, Bakenhaster and Adams in 2015.

[3] The species was named in honor of Dr. Luis René Capurro Filograsso, "in recognition to his guidance, kindness and support of Mexican students.

The morphology of the anchors, ventral bar, hooks, and vaginal sclerite is nearly identical to that of P. kritskyi, which differs most significantly from P. capurroi by possessing dorsal bars with enlarged bilobed medial ends and lacking the twisted nature of those of P. capurroi.

The type-host and only recorded host is the Black grouper, Mycteroperca bonaci (Serranidae: Epinephelinae).
