Capsalidae [1] [2] is a family of monopisthocotylean monogeneans, which includes about 200 species. [3]
The monophyly of the Capsalidae is supported by possession of accessory sclerites [3] in the haptor (the posterior attachment organ), and was confirmed by molecular phylogeny. [4] Their oncomiracidium (the free larva) is distinct from that of other families. [5]
Capsalids are parasite on various organs of marine fish (teleosts and elasmobranchs), including skin, fins and gills. [3] Several capsalid species, such a Neobenedenia spp. [6] are pathogenic, especially on maricultured fish.
Genera as recognized in WorMs are listed below. Recent molecular analyses have shown that several genera, which were defined on morphological characters, are not monophyletic. [4]
Menziesia and Nitzschia have their equivalent in the botanical nomenclature: Menziesia (a flowering plant) and Nitzschia (a diatom).
Neobenedenia is a genus of monopisthocotylean monogenean flatworm parasites.
Microcotyle is a genus which belongs to the phylum Platyhelminthes and class Monogenea. Species of Microcotyle are ectoparasites that affect their host by attaching themselves as larvae on the gills of the fish and grow into adult stage. This larval stage is called oncomiracidium, and is characterized as free swimming and ciliated.
The haptor is the attachment organ of the monogeneans, a group of parasitic Platyhelminthes. The haptor is sometimes called opisthaptor to emphasize that it is located in the posterior part of the body, and to differentiate it from the prohaptor, a structure including glands located at the anterior part of the body. According to Yamaguti (1963), the chief adhesive organ of the monogeneans, the haptor, is posterior, more or less discoid, muscular, may be divided into alveoli or loculi, is usually provided with anchors, has nearly always marginal larval hooklets, or is in a reduced form with anchors. The haptor may consist of symmetrical or asymmetrical, sessile or pedunculate, muscular suckers or clamps with or without supporting sclerites; accessory adhesive organs may be present in form of armed plaques, lappets or appendices.
Pseudorhabdosynochus is a genus of monopisthocotylean monogeneans, included in the family Diplectanidae. The type-species of the genus is Pseudorhabdosynochus epinepheli .
The Diplectanidae are a family of monopisthocotylean monogeneans. They are all parasitic on the gills of fish. 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.
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.
Pseudorhabdosynochus epinepheli is a diplectanid monogenean parasitic on the gills of species of groupers. It is the type species of the genus Pseudorhabdosynochus Yamaguti, 1958.
Lee Hong Susan Lim, more commonly known as Susan Lim, was a Malaysian parasitologist who specialised on the Monogenea, a class of parasitic flatworms which are important ectoparasites of fishes. She was the first and only Malaysian commissioner elected to the International Commission on Zoological Nomenclature. Her research was mainly in the fields of taxonomy and faunistics, although in later years, she became involved in a wide range of parasitological disciplines.
Lagenivaginopseudobenedenia is a genus of monopisthocotylean monogenean, included in the family Capsalidae. The type-species of the genus is Lagenivaginopseudobenedenia etelisYamaguti, 1966. The genus includes only 2 species, which are both parasitic on the gills of marine fish of the family Lutjanidae.
Alexandr Vladimirovich Gussev, sometimes spelled Gusev in the literature, was a Russian helminthologist specialist of monogeneans.
Louis Euzet was a French parasitologist.
Lamellodiscus is a genus of monopisthocotylean monogeneans in the family Diplectanidae; all species of Lamellodiscus are small worms, parasitic on the gills of teleost fish.
Plectanocotylidae is a family of polyopisthocotylean monogeneans. All the species in this family are parasitic on the gills of marine fish.
Allobenedenia is a genus of monopisthocotylean monogeneans, included in the family Capsalidae. All species in this genus are parasitic on external surfaces of marine teleosts.
Ancyrocephalidae is a family of monogenean flatworms. The family is considered as a "temporary name" in WorMS but includes a large number of genera and species.
Delane C. Kritsky is an American parasitologist who specialised on the Monogenea, a class of parasitic flatworms which are important ectoparasites of fishes. His research was mainly in the fields of taxonomy, faunistics, and phylogeny of the Monogenea.
Pseudorhabdosynochus cupatus is a species of diplectanid monogenean parasitic on the gills of groupers.
Lobotrema is a genus of monopisthocotylean monogeneans, belonging to the family Diplectanidae. All its species are parasites on fish. The type-species is Lobotrema madrasiTripathi, 1959.
Murraytrematoides is a genus of monopisthocotylean monogeneans in the family Diplectanidae.
Rhabdosynochus is a genus of monopisthocotylean monogeneans, belonging to the family Diplectanidae.
