Lagenivaginopseudobenedenia
''Lagenivaginopseudobenedenia'' is a genus of monopisthocotylean monogenean (a group of ectoparasitic flatworms), included in the family Capsalidae.Whittington, I. D. 2004: The Capsalidae (Monogenea: Monopisthocotylea): a review of diversity, classification and phylogeny with a note about species complexes. Folia Parasitologica, 51, 109-122PDF The type-species of the genus is '' Lagenivaginopseudobenedenia etelis'' Yamaguti, 1966.Yamaguti S. 1966. New monogenetic trematodes from Hawaiian fishes, II. Pacific Science 20(4): 419-434PDF The genus includes only 2 species, which are both parasitic on the gills of marine fish of the family Lutjanidae. Morphology Species of the genus ''Lagenivaginopseudobenedenia'' are, like most monogeneans of the family Capsalidae, flat with a posterior disc-shaped haptor which attaches to the gill of their host. Their distinctive feature is a “vagina lageniform, between uterus and right intestinal limb, opening almost midventrally behind cirrus pou ...

Satyu Yamaguti
was a Japanese parasitologist, entomologist, and helminthologist. He was a specialist of mosquitoes and helminths such as digeneans, monogeneans, cestodes, acanthocephalans and nematodes. He also worked on the parasitic crustaceans Copepoda and Branchiura. Satyu Yamaguti wrote more than 60 scientific papersAnonymous. 1983. Special edition: A list of papers by Dr. Satyu Yamaguti and his collaborators and a notice on their distribution. The Meguro Parasitological Museum News, 153 (58), 1-12PDF and, more importantly, several huge monographs which are still in use by scientists all over the world and were cited over 1,000 times each. Education and career Satyu Yamaguti was born in Nagano Prefecture, Japan, 21 April 1894. He graduated from Okayama Medical College (1918), studied pathology at Tokyo University (1918-1925) and parasitology at the Institut für Tropenkrankheiten in Hamburg, Germany (1925-1926). He received his MD from Tokyo University in 1926 and was Dr. Sc. of Kyoto U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudobenedenia
Capsalidae Yamaguti, S. (1963) Systema Helminthum IV. Monogenea and Aspidocotylea. London-New York, Interscience Publishers. 699 pp. is a family of monopisthocotylean monogeneans, which includes about 200 species. The monophyly of the Capsalidae is supported by possession of accessory sclerites in the haptor (the posterior attachment organ), and was confirmed by molecular phylogeny. Their oncomiracidium (the free larva) is distinct from that of other families. Capsalids are parasite on various organs of marine fish (teleosts and elasmobranchs), including skin, fins and gills. Several capsalid species, such a ''Neobenedenia'' spp. are pathogenic, especially on maricultured fish. Included genera Genera as recognized iWorMsare listed below. Recent molecular analyses have shown that several genera, which were defined on morphological characters, are not monophyletic.

Etelis Carbunculus
''Etelis carbunculus'', the deep-water red snapper, ruby snapper, longtail snapper, or ehu, is a species of ray-finned fish, a snapper belonging to the Family (biology), family Lutjanidae. It is found in the Indo-Pacific region. Description ''Etelis carbunculus'' is an elongated fish with a small head and a large eye, the space between the eyes is flat. The mouth extends back as far as the middle of the eye and the jaws are each equipped with a single row of conical teeth with one or two pairs of enlarged canines at the front. The vomerine teeth are arranged in a slender V-shaped patch. The forked caudal fin has relatively short lobes in comparison to congeners. It has a continuous dorsal fin which has a deep notch at the junction of its spiny part and the ultimate soft ray of both the dorsal and anal fins extends beyond the membrane, being longer than the penultimate ray. The dorsal fin contains 10 spines and 11 soft rays while the anal fin has 3 spines and 8 soft rays, both fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Code Of Zoological Nomenclature
The International Code of Zoological Nomenclature (ICZN) is a widely accepted Convention (norm), convention in zoology that rules the formal scientific name, scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its formal author, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of Binomial nomenclature, binominal nomenclature * How to determine whether a given name is Available name, available * Which available name must be used in case of name conflicts (Valid name (zoology), valid name) * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus ''Abronia (other), Abronia'' in both animals and plants). The rules and re ...

Monogenea
Monogeneans, members of the class Monogenea, are a group of ectoparasitic flatworms commonly found on the skin, gills, or fins of fish. They have a direct lifecycle and do not require an intermediate host. Adults are hermaphrodites, meaning they have both male and female reproductive structures.L.A. Tubbsa et al. (2005). "Effects of temperature on fecundity in vitro, egg hatching and reproductive development of ''Benedenia seriolae'' and ''Zeuxapta seriolae'' (Monogenea) parasitic on yellowtail kingfish Seriola lalandi". ''International Journal for Parasitology''(35), 315–327. Some monogeneans are oviparous (egg-laying) and some are viviparous (live-bearing). Oviparous varieties release eggs into the water. Viviparous varieties release larvae, which immediately attach to another host. The genus ''Gyrodactylus'' is an example of a viviparous variety, while the genus ''Dactylogyrus'' is an example of an oviparous variety. Signs and symptoms Freshwater fish that become infect ...

New Caledonia
New Caledonia ( ; ) is a group of islands in the southwest Pacific Ocean, southwest of Vanuatu and east of Australia. Located from Metropolitan France, it forms a Overseas France#Sui generis collectivity, ''sui generis'' collectivity of the French Republic, a legal status unique in overseas France, and is enshrined in a dedicated chapter of the French Constitution. The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre (New Caledonia), Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines (New Caledonia), Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. French people, especially locals, call Grande Terre , a nickname also used more generally for the entire New Caledonia. Kanak people#Agitation for independence, Pro-independence Kanak parties use the name (''pron.'' ) to refer to New Caledonia, a term coined in the 1980s from the ethnic name of the indi ...

Etelis Coruscans
''Etelis coruscans'', commonly known as the longtail snapper or deep-water red snapper, is a species of snapper found in the Pacific and Indian oceans. It is a valuable commercial species, and lives quite deep – from . It is a long-lived species that grows and matures slowly. In Hawai'i the fish is widely known as onaga.
