Description

edit

Pseudorhabdosynochus pai is a small monogenean, 0.3-0.7 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] but Pseudorhabdosynochus pai is characterised by an extremely developed male quadriloculate organ: its total length is 140 μm and thus the species appears to have the largest quadriloculate organ of all species in the genus.[1] The vagina includes a sclerotized part, which is a complex structure.[1]

Etymology

edit

The authors indicated that Pai is a legendary (male) hero of Moorea.[1]
