Pseudorhabdosynochus Yucatanensis
''Pseudorhabdosynochus yucatanensis'' is a diplectanid monogenean parasitic on the gills of the red grouper, ''Epinephelus morio''. It was described by Vidal-Martínez, Aguirre-Macedo & Mendoza-Franco in 1997Vidal-Martínez, V. M., Aguirre-Macedo, L. & Mendoza-Franco, E. F. 1997: ''Pseudorhabdosynochus yucatanensis'' sp. n. (Monogenea: Diplectanidae) from the gills of the red grouper ''Epinephelus morio'' (Pisces: Serranidae) of the Yucatan Peninsula, Mexico" ''Folia Parasitologica'' 44, 274-278PDF and redescribed by Kritsky, Bakenhaster and Adams in 2015. Description ''Pseudorhabdosynochus americanus'' is a small monogenean. 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 ...

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 ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campeche
Campeche (; yua, Kaampech ), officially the Free and Sovereign State of Campeche ( es, Estado Libre y Soberano de Campeche), is one of the 31 states which make up the 32 Federal Entities of Mexico. Located in southeast Mexico, it is bordered by the states of Tabasco to the southwest, Yucatán to the northeast, and Quintana Roo to the east; to the southeast by the Orange Walk district of Belize, and by the Petén department of Guatemala to the south.

The formation of the state began with the city, which was founded in 1540 as the Spanish began the conquest of the Yucatán Peninsula. The city was a rich and important port during the colonial period, but it declined after Mexico's independence. Campeche was part of the province of Yucatán but split off in the mid-19th century, mostly due to political friction with the city of Mérida. Much ...
