Gastrocotylinae is a sub-family of polyopisthocotylean monogeneans. All the species in this family are parasitic on fish. [1] [2]
According to the Lebedev (1986) [3] the sub-family includes 17 valid genera:
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 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.
The Capsalidae is a family of monopisthocotylean monogeneans, which includes about 200 species.
Hexabothriidae is a family of monogenean parasites. The family name was proposed by Emmett W. Price in 1942. The family includes 14-16 genera according to authors and about 60 species; all are parasitic on the gills of chondrichthyan fishes.
Gastrocotylidae is a family of polyopisthocotylean monogeneans. All the species in this family are parasitic on fish.
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.
Microcotyle archosargi is a species of monogenean, parasitic on the gills of a marine fish. It belongs to the family Microcotylidae. It was first described by MacCallum in 1913 based on ten specimens. Hargis (1956) pointed out that the description and figures given by MacCallum were poor in details.
Rhabdosynochus is a genus of monopisthocotylean monogeneans, belonging to the family Diplectanidae.
Pseudaxine is a genus which belongs to the phylum Platyhelminthes and class Monogenea; all its species are parasites of fish.
Pseudaxine indicana is a species of monogenean flatworm, which is parasitic on the gills of a marine fish. It belongs to the family Gastrocotylidae.
Pseudaxine bivaginalis is a species of monogenean flatworm, which is parasitic on the gills of a marine fish. It belongs to the family Gastrocotylidae.
Sibitrema is a genus which belongs to the phylum Platyhelminthes and class Monogenea; the only species included in this genus is parasite of fish.
Sibitrema poonui is a species of monogenean flatworm, which is parasitic on the gills of a marine fish. It belongs to the family Gastrocotylidae.
Allopseudaxine is a genus which belongs to the phylum Platyhelminthes and class Monogenea; all its species are parasites of fish.
Allopseudaxine katsuwonis is a species of monogenean flatworm, which is parasitic on the gills of a marine fish. It belongs to the family Axinidae.
Microcotylinae is a subfamily within family Microcotylidae and class Monogenea. This subfamily was created by Taschenberg in 1879.
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.
Diplostamenides is a genus which belongs to the family Microcotylidae and class Monogenea. As all Monogenea, species of Atriostella 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.
