Pseudorhabdosynochus serrani is a species of diplectanid monogenean parasitic on the gills of a fish.

It was described in 1953 by Satyu Yamaguti as Diplectanum serrani [1] and later transferred to the genus Pseudorhabdosynochus.

[3] Pseudorhabdosynochus serrani is a small monogenean, 0.3-0.4 mm in length.

The etymology of the specific epithet is not explained in the original description [1] but obviously refers to the genus of the host fish, Serranus.

The type-locality is off Makassar (Indonesia), and the type-host is an unnamed fish of the genus Serranus.
