The Cumacean (Crustacea: Peracarida) Genus Petalosarsia (Pseudocumatidae) from the Pacific Ocean

  title={The Cumacean (Crustacea: Peracarida) Genus Petalosarsia (Pseudocumatidae) from the Pacific Ocean},
  author={Tadashi Akiyama and Sarah Gerken},
The distribution of the cumacean family Pseudocumatidae is restricted to the North Atlantic, Mediterranean and brackishwaters of the Pont-Caspian region, except for three known species of the genus Petalosarsia. The present study describes ninespecies of Petalosarsia from Japanese waters, the Sulu Sea, the North-west Pacific, the Indo-West Pacific, and the Tasman Sea,Australia. The occurrence of P. declivis (Sars, 1865) in northern Hokkaido agrees with the reported circumpolar distribution… 
Two new species of Atlantocuma (Crustacea: Cumacea), and a new genus and species from Japan, Northwest Pacific, with observations on the degeneration of mouthparts in ovigerous females
Two species of the cumacean genus Atlantocuma from the southern coast of Honshu, Japan, and Pseudopicrocuma japonicum gen et sp.
Eleven new species and a new genus of Diastylidae (Crustacea: Cumacea) from Australia and one new species from Canada
Keys to all Australian diastylid species are provided, as are global keys to all species of Diastylopsis and Paradiastylis.
Deep-sea Bodotriidae, Diastylidae and Pseudocumatidae (Cumacea, Crustacea) from the southeastern Atlantic.
The distribution range is enlarged based on the new findings for seven species and one of the new species has to remain in open nomenclature due to its young developmental stage.
First multigene phylogeny of Cumacea (crustacea: Peracarida)
A phylogeny based on Bayesian inference of six markers is presented, which recovers monophyly of the order, a deep split between telson and pleotelson bearing groups, and monophyle of four of the seven included families, including monophyletic Pseudocumatidae, Lampropidae, Bodotriidae and Nannastacidae.
An Overview of Recent Marine Biodiversity Research in Japan
We review recent activities pertaining to taxonomic studies of marine animals, mostly invertebrates, in Japanese waters. Frequent field workshops have increased our knowledge of local faunas. Minute


Kerguelenica petrescui (Crustacea: Cumacea), A New Species from Australian Waters
A new species of Kerguelenica is described from specimens collected from the continental slope of Australia and Tasmania, from depths of 1000-1800 m.
Amphi‐Atlantic distribution of the Mancocumatinae (Cumacea: Bodotriidae), with description of a new genus dwelling in marine lava caves of Tenerife (Canary Islands)
Correlation between phylogenetic relationships of the new genus and the geological history of the Canarian archipelago points to a probable origin of this endemism: the subfamily Mancocumatinae show a disjunct distribution on both sides of the Atlantic Ocean, a pattern which has been associated with fauna of Tethyan origin.
Global diversity of cumaceans & tanaidaceans (Crustacea: Cumacea & Tanaidacea) in freshwater
Cumacea and Tanaidacea are marginal groups in continental waters. Although many euryhaline species from both groups are found in estuaries and coastal lagoons, most occur only temporarily in
Systematics of the genera of Bodotriidae (Crustacea: Cumacea)
Phylogenetic analyses show that there is independent reduction of the pleopods in two clades from a plesiomorphic state of five pairs, while the number of exopods of peraeopods has been reduced gradually in more derived groups of bodotriids.
Les Cumacés (Crustacea) des campagnes Eumeli 2, 3 et 4 au large du Cap Blanc (est Atlantique tropical)
During the Eumeli Atlantic cruises, samples were taken between 1600 and 4600 m in three different areas and five species proved to be new to science: Cyclaspis pseudolongicaudata, n.
Monopseudocuma a new genus from the North East Atlantic and redescription of Pseudocuma gilsoni Bacescu, 1950 (Cumacea: Pseudocumatidae)
A new genus, Monopseudocuma, is erected to accommodate the species, and a neotype is designated from the West coast of Ireland, confirming the presence of the species in the North East Atlantic.
Some New Cumacea From Deep Water in the Atlantic 1)

Five Collections of Cumacea from the Alaskan Arctic
Lists, with detailed morphologic and taxonomic information, several species of these crustaceans collected 1948-1950 by various parties, with some taxonomically significant variations noted.
