Pseudorhabdosynochus contubernalis is a diplectanid monogenean parasitic on the gills of the Scamp, Mycteroperca phenax.

The specific name (a noun) is from Latin (contubernalis = a companion or comrade) and refers to its co-occurrence with P. vascellum on Mycteroperca phenax.

[1] Kritsky, Bakenhaster & Adams (2015) wrote that Pseudorhabdosynochus contubernalis most closely resembles P. vascellum.

In addition, the proximal two chambers of the male copulatory organ of P. contubernalis have comparatively thin walls which frequently have collapsed or are absent.

[1] The type-host and only recorded host of Pseudorhabdosynochus vascellum is the scamp, Mycteroperca phenax (Serranidae: Epinephelinae).
