TheDiplectanidae are a family ofmonopisthocotyleanmonogeneans. They are all parasitic on thegills offish (marine or freshwater). Diplectanids are small animals, generally around 1 mm in length. Asparasites, they can be extremely numerous, up to several thousand on an individual fish.
The family Diplectanidae was proposed by the Italian parasitologistMonticelli in 1903 (as subfamily Diplectaninae).[1] The status of the family and its components was later examined by various authors, including Johnston &Tiegs (1922),[2] Price (1937),[3]Bychowsky (1957),[4]Yamaguti (1963),[5] and Oliver (1987).[6]
Diplectanids are diagnosed by the combination of these three characters:
Presence of accessory adhesive organs on dorsal and ventral part of thehaptor, calledsquamodiscs when they are made up of rodlets andlamellodiscs when they include lamellae
In the haptor, three transversal bars (one ventral, two lateral (dorsal), connected to two pairs of hooks (one pair dorsal, one pair ventral)
A germarium (or ovary) which is anterior to the testis and loops around the right intestinal caecum
