The redescription by Kritsky, Bakenhaster & Adams in 2015 includes the following: Body elongate ovate, flattened dorsoventrally, with slight constriction at level of male copulatory organ (MCO).

Pharynx ovate, muscular; esophagus short to nonexistent; intestinal ceca blind, extending posteriorly to level of peduncle.

Testis subspherical, lying immediately posterior to germarium; proximal vas deferens not observed; seminal vesicle a simple dilation of distal vas deferens, lying just posterior to MCO; ejaculatory bulb apparently absent; large vesicle (prostatic reservoir?)

Germarium pyriform; germarial bulb lying slightly to right of body midline, with elongate dorsoventral distal loop around right intestinal cecum; ootype lying slightly to left of body midline, with well-developed Mehlis’ gland and giving rise to delicate banana-shaped uterus when empty.

Bilateral and common vitelline ducts not observed; vitellarium absent in regions of other reproductive organs, otherwise extending from level of MCO to anterior limit of peduncle.

[2] Kritsky, Bakenhaster & Adams (2015) wrote that "examination of the holotype, three paratypes, and voucher specimens from red grouper off Florida and Mississippi indicated that the original description of P. yucatanensis was based on specimens representing two distinct species of Pseudorhabdosynochus", namely P. yucatanensis sensu stricto and P. justinella Kritsky, Bakenhaster & Adams, 2015.
