Pseudorhabdosynochus Kritskyi
''Pseudorhabdosynochus kritskyi'' is a diplectanid monogenean parasitic on the gills of the gag, ''Mycteroperca microlepis''. The species has been described by Dyer, Williams and Bunkley-Williams in 1995 and redescribed successively by Yang, Gibson and Zeng in 2005 and by Kritsky, Bakenhaster and Adams in 2015. The name of the species honours the American parasitologist Delane C. Kritsky. Description ''Pseudorhabdosynochus kritskyi'' is a small monogenean, less than 1 mm (700 μm) long. The species has the general characteristics of other species of ''Pseudorhabdosynochus'', with a flat body and a posterior haptor, which is the organ by which the monogenean attaches itself to the gill of is host. The haptor bears two squamodiscs, one ventral and one dorsal. The sclerotized male copulatory organ, or "quadriloculate organ", has the shape of a bean with four internal chambers, as in other species of ''Pseudorhabdosynochus''. The vagina includes a sclerotized part, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diplectanidae
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). The status of the family and its components was later examined by various authors, including Johnston & Tiegs (1922), Price (1937),Price, E. W. 1937: North American Monogenetic Trematodes. I. The superfamily Gyrodactyloidea ''Journal of the Washington Academy of Sciences'' 27, 146-164PDF Bychowsky (1957), Yamaguti (1963), and Oliver (1987). Morphology 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 lame ...
