Onceroxenus is a genus of crustaceans belonging to the monotypic family Onceroxenidae. [1]
The species of this genus are found in Western Europe. [1]
Species: [1]
Tantulocarida is a highly specialised group of parasitic crustaceans that consists of about 33 species, treated as a class in superclass Multicrustacea. They are typically ectoparasites that infest copepods, isopods, tanaids, amphipods and ostracods.
Cumoniscidae is a family of crustaceans in the class Tantulocarida, classified under the superclass Multicrustacea. The family was previously known as Deoterthridae, but Cumoniscidae was determined to be senior subjective synonym.
Calanus is a genus of marine copepod in the family Calanidae. The genus was split in 1974, with some species being placed in a new genus, Neocalanus. The following species are recognised:
Allodiaptomus is a genus of copepods in the family Diaptomidae, containing the following species:
Epischura is a genus of copepods in the family Temoridae.
Notodiaptomus is a genus of copepods in the family Diaptomidae. It is the most widely distributed, most abundant and most species-rich genus of freshwater calanoid copepods in the Neotropics. The genus was erected in 1936 by Friedrich Kiefer for eleven species formerly placed in a wider Diaptomus. Notodiaptomus deitersi was chosen to be the type species by Raúl Adolfo Ringuelet in 1958.
Ponticyclops is a genus of copepods in the family Cyclopidae. It is monotypic, being represented by the single species Ponticyclops boscoi. It is endemic to Brazil, where its natural habitat is swamps.
Speleophria is a genus of marine copepods in the family Speleophriidae. It contains the following species:
Oncaea is a genus of copepods. The genus contains bioluminescent species. Unlike other bioluminescent copepods, Oncaea have an internal (non-secreted) bioluminescence. Oncaea contains the following species:
Calocalanus is a genus of copepods, the only genus in the family Calocalanidae:
Stygotantulus is a genus of crustacean with the sole species Stygotantulus stocki. It lives as an ectoparasite on harpacticoid copepods of the families Tisbidae and Canuellidae. It may be the smallest arthropod in the world, at a length of less than 0.1 millimetres (0.004 in). The specific name stocki commemorates Jan Hendrik Stock, a Dutch carcinologist.
Gaussia is a genus of copepods. The genus contains bioluminescent species. It is a "characteristic genus of the mesopelagial", occurring at depths of 0–3,000 metres (0–9,843 ft). The genus Gaussia contains the following species:
Nicothoidae is a family of copepods, containing the following genera:
The clade Multicrustacea constitutes the largest superclass of crustaceans, containing approximately four-fifths of all described crustacean species, including crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, barnacles, copepods, amphipods, mantis shrimp and others. The largest branch of multicrustacea is the class Malacostraca.
Peniculus is a genus of marine copepods in the family Pennellidae. They occur worldwide and typically parasitize coastal or epipelagic fish, with the exception of Peniculus hokutoae that was found parasitizing a mesopelagic myctophid, Symbolophorus evermanni.
Peniculus hokutoae is a species of parasitic pennellid copepod. It was described in 2018 from a single female. The type-host is the myctophid fish Symbolophorus evermanni and the type-locality is off Japan. The Japanese name of this species is hokuto-kozutsu-hijikimushi.
Urocopia is a genus of cyclopoid copepods in the family Urocopiidae, the sole genus of the family. There are at least three described species in Urocopia.
Spiophanicola is a genus of cyclopoid copepods in the family Spiophanicolidae, the sole genus of the family. There are at least two described species in Spiophanicola.
Hyalopontius is a genus of crustaceans belonging to the monotypic family Megapontiidae.
Palpophria is a monotypic genus of crustaceans belonging to the monotypic family Palpophriidae. The only species is Palpophria aestheta.
