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
TLDR
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
TLDR
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.
TLDR
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)
TLDR
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

Amphi‐Atlantic distribution of the Mancocumatinae (Cumacea: Bodotriidae), with description of a new genus dwelling in marine lava caves of Tenerife (Canary Islands)
TLDR
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)
TLDR
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.
