Diplectanidae
The Diplectanidae are a family of monopisthocotylean monogeneans. They are all parasitic on the gills of fish (marine or freshwater). Diplectanids are small animals, generally around 1 mm in length. As parasites, they can be extremely numerous, up to several thousand on an individual fish. History The family Diplectanidae was proposed by the Italian parasitologist Francesco Saverio Monticelli, Monticelli in 1903 (as subfamily Diplectaninae). The status of the family and its components was later examined by various authors, including Johnston & Oscar Werner Tiegs, Tiegs (1922), Price (1937),Price, E.

Calydiscoides
''Calydiscoides'' is a genus of monopisthocotylean monogeneans, included in the family Diplectanidae. The genus currently includes 16 species, which are all parasitic on the gills of marine fish of the family Lethrinidae and Nemipteridae. All species are from the Indo-Pacific Ocean. The type-species of the genus is '' Calydiscoides australis'' Young, 1969. Morphology All species of ''Calydiscoides'' are small animals, ranging 0.5–1 mm in length. As with most monogeneans, they are flat, with an anterior head bearing four oculi and head glands, a main elongate body and a posterior haptor. The digestive system includes an anterior muscular pharynx, and two lateral intestinal branches (or caeca); as in all Platyhelminthes, there is no anus. The haptor, in the posterior part of the body, is a specialized organ used to attach to the host. The haptor includes sclerotized elements, namely a ventral bar, two lateral (dorsal) bars, two ventral hooks, and two dorsal hooks, and fo ...

Squamodisc
Squamodiscs are epidermal structures, which are typical of and found only in certain monogeneans of the family Diplectanidae. There are, typically, two squamodiscs, one ventral and one dorsal, located on the haptor of the monogenean. Squamodiscs are usually made up of scales embedded in the epidermis, which appear from the outside as rodlets arranged in rows. According to the classical book of Bychowsky (1967), Bychowsky, B. E.

Lamellodisc
Lamellodiscs are epidermal structures, which are typical of and found only in certain monogeneans of the family Diplectanidae. There are, typically, two lamellodiscs, one ventral and one dorsal, located on the haptor of the monogenean. Lamellodiscs are made up of concentric lamellae embedded in the epidermis. Lamellodiscs are considered as special type of squamodiscs, which are homologous structure found in many diplectanid monogeneans but formed of rows of rodlets instead of lamellae. Lamellodiscs are found in members of the diplectanid genera ''Lamellodiscus ''Lamellodiscus'' is a genus of monopisthocotylean monogeneans in the family Diplectanidae; all species of ''Lamellodiscus'' are small worms, Fish diseases and parasites, parasitic on the gills of teleost fish.

Pseudorhabdosynochus Morrhua
''Pseudorhabdosynochus morrhua'' is a diplectanid monogenean parasitic on the gills of the grouper '' Epinephelus morrhua''. It has been described in 2008. Description ''Pseudorhabdosynochus morrhua'' is a small monogenean, 0.25 mm–0.48 mm in length. 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 sclerotized male copulatory organ, or "quadriloculate organ", has the shape of a bean with four internal chambers, as in other species of '' Pseudorhabdosynochus''. The vagina includes a sclerotized part, which is a complex structure. Etymology The name of the parasite is from the host name, '' Epinephelus morrhua''.
