Lagenivaginopseudobenedenia is a genus of monopisthocotylean monogenean (a group of ectoparasitic flatworms), included in the family Capsalidae. [1] The type-species of the genus is Lagenivaginopseudobenedenia etelis Yamaguti, 1966. [2] The genus includes only 2 species, which are both parasitic on the gills of marine fish of the family Lutjanidae.
Species of the genus Lagenivaginopseudobenedenia are, like most monogeneans of the family Capsalidae, flat with a posterior disc-shaped haptor which attaches to the gill of their host. Their distinctive feature is a “vagina lageniform, between uterus and right intestinal limb, opening almost midventrally behind cirrus pouch”. [2]
The etymology of this extremely long name involves three steps:
Lagenivaginopseudobenedenia, with 27 letters and 17 syllables, is possibly the longest valid generic name of the zoological nomenclature for a non-fossil organism. [1] [5]
Hosts of species of monogeneans of the genus Lagenivaginopseudobenedenia are parasitic on fish which are members of the genus Etelis (family Lutjanidae), found in deep-sea in the Pacific Ocean.
Only two species are currently known in this genus.
Neobenedenia is a genus of monopisthocotylean monogenean flatworm parasites.
Lutjanidae, or snappers are a family of perciform fish, mainly marine, but with some members inhabiting estuaries, feeding in fresh water. The family includes about 113 species. Some are important food fish. One of the best known is the red snapper.
Etelis is a genus of marine ray-finned fish belonging to the family Lutjanidae, the snappers. They are mostly native to the Indian and Pacific oceans with one species (E. oculatus) native to the western Atlantic Ocean.
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.
Satyu Yamaguti was a Japanese parasitologist, entomologist, and helminthologist. He was a specialist of mosquitoes and helminths such as digeneans, monogeneans, cestodes, acanthocephalans and nematodes. He also worked on the parasitic crustaceans Copepoda and Branchiura. Satyu Yamaguti wrote more than 60 scientific papers and, more importantly, several huge monographs which are still in use by scientists all over the world and were cited over 1,000 times each.
Capsalidae is a family of monopisthocotylean monogeneans, which includes about 200 species.
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.
Bentholebouria is a genus of trematodes in the family Opecoelidae.
Pseudorhabdosynochus cupatus is a species of diplectanid monogenean parasitic on the gills of groupers.
Pseudorhabdosynochus melanesiensis is a diplectanid monogenean parasitic on the gills of the grouper, Epinephelus merra. It was described in 1958 as Diplectanum melanesiensis then transferred to the genus Pseudorhabdosynochus by Kritsky & Beverley-Burton in 1986.
Microcotyle sebastis is a species of monogenean, parasitic on the gills of a marine fish. It belongs to the family Microcotylidae.
Microcotyle pomatomi is a species of monogenean that is parasitic on the gills of a marine fish. It belongs to the family Microcotylidae.
Microcotyle jonii is a species of monogenean, parasitic on the gills of a marine fish. It belongs to the family Microcotylidae. It was described from the gills of Lutjanus jonii (Lutjanidae) from Karachi coast off Pakistan.
Pseudaxine is a genus which belongs to the phylum Platyhelminthes and class Monogenea; all its species are parasites of fish.
Allopseudaxine is a genus which belongs to the phylum Platyhelminthes and class Monogenea; all its species are parasites of fish.
Bivagina is a genus of monogeneans. As all Monogenea, species in the genus are ectoparasites that affect their host by attaching themselves as larvae on the gills of fish and grow into adult stage. This larval stage is called oncomiracidium, and is characterized as free swimming and ciliated.
Etelis carbunculus, the deep-water red snapper, ruby snapper, longtail snapper, or ehu, is a species of ray-finned fish, a snapper belonging to the family Lutjanidae. It is found in the Indo-Pacific region.
