The Diplectanidae are a family of monopisthocotylean monogeneans. They are all parasitic on the gills of fish (marine or freshwater). 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.

History
The family Diplectanidae was proposed by the Italian parasitologist Monticelli 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]
Morphology
_Fig3b_Haptor.png)
Diplectanids are diagnosed by the combination of these three characters:
- Presence of accessory adhesive organs on dorsal and ventral part of the haptor, called squamodiscs when they are made up of rodlets and lamellodiscs 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
