Cichlidogyrus

Cichlidogyrus is a genus of monopisthocotylean monogeneans in the family Ancyrocephalidae. The type-species of the genus is Cichlidogyrus arthracanthus Paperna, 1960, by original designation.^[1] All the species of the genus are parasites on the gills of fish, namely African Cichlidae, Nandidae and Cyprinodontidae.^{[1] [2] [3] [4] [5] [6] [7] [8]}

Scientific classification
Domain:	Eukaryota
Kingdom:	Animalia
Phylum:	Platyhelminthes
Class:	Monogenea
Order:	Dactylogyridea
Family:	Ancyrocephalidae
Genus:	Cichlidogyrus Paperna, 1960 [1]

Species of Cichlidogyrus are parasitic in many cichlid species in the Lake Tanganyika; a recent study (2016) has shown that species which are parasite on deep-water fish show reduced parasite-host specificity in comparison to species from littoral waters, probably an adaptation to low host availability.^[9]

According to Antoine Pariselle and Louis Euzet, 71 species of Cichlidogyrus were known in 2009 ^[3] - new species have been described since. Nikol Kmentová, Milan Gelnar, Stephan Koblmüller and Maarten P.M. Vanhove estimated that the number of species was more than 100 in 2016^[10] and Chahrazed Rahmouni, Maarten P. M. Vanhove and Andrea Šimková listed 111 species in 2017.^[11]

Species of Cichlidogyrus have been introduced in various parts of the world, as alien species, where their hosts, particularly tilapia, have been introduced.^[12]
