It was described in 2010.[1] DescriptionPseudorhabdosynochus exoticoides is a small monogenean, 0.3-0.4 mm in length.[1] 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. It comprises a discoid structure with central dome and an internal (dorsal) structure of variable shape.[1] EtymologyAccording to the authors of the taxon, the specific name, exoticoides, is based on the Latin exoticus, the name of a similar species (Pseudorhabdosynochus exoticus), plus the suffix –oides, resembling.[1] Hosts and localitiesThe type-host and only recorded host of P. exoticoides is the brownspotted grouper Epinephelus chlorostigma. The type-locality and only recorded locality is external slope of the barrier reef off Nouméa, New Caledonia. [1] In New Caledonia where it was investigated, this fish species harbours on its gill a series of seven species of monogeneans, including the ancyrocephalid Haliotrema sp., the capsalid Allobenedenia cf. epinepheli Yamaguti, 1968, and five diplectanids, namely Pseudorhabdosynochus epinepheli (Yamaguti, 1938), Pseudorhabdosynochus cyanopodus Sigura & Justine, 2008, Pseudorhabdosynochus podocyanus Sigura & Justine, 2008, Pseudorhabdosynochus stigmosus Justine & Henry, 2010, Pseudorhabdosynochus exoticoides Justine & Henry, 2010, and Diplectanum femineum Justine & Henry, 2010.[1] References1. ^1 2 3 4 5 {{cite journal|last1=Justine|first1=Jean-Lou|last2=Henry|first2=Émilie|title=Monogeneans from Epinephelus chlorostigma (Val.)
