  • 1994
TLDR
A new rhynchocinetid shrimp is described, most closely related to R. rugulosus Stimpson from Australia, but can be distinguished from the latter species by having a shorter stylocerite.
Designation of Ancylomenes gen. nov., for the 'Periclimenes aesopius species group' (Crustacea: Decapoda: Palaemonidae), with the description of a new species and a checklist of congeneric species*
A new genus of the subfamily Pontoniinae, Ancylomenes gen. nov. is established for the ‘Periclimenes aesopius species group’ of the genus Periclimenes Costa. The new genus is distinguished from other…

Abstract A new species of palaemonid shrimp, Periclimenes speciosus sp. nov., is described and illustrated on the basis of 20 specimens collected from warm-temperate and subtropical waters of…
A new species of the genus Periclimenes Costa, 1844 (Crustacea: Decapoda: Palaemonidae) from the Ryukyu Islands, southern Japan
A new species of pontoniinid shrimp, Periclimenes dolichosternum, is described and illustrated on the basis of 21 specimens collected from sublittoral zones of the Ryukyu Islands at depths of 1.5-30…
Studies on Eumalacostraca: a homage to Masatsune Takeda
TLDR
A summary of relevant morphological evidence and a hypothesis about the evolution of camouflage in dromiid crabs is provided and the morphological and behavioural characters will need to be eventually mapped on to a molecular phylogeny.
Cuapetes Clark, 1919, a senior synonym of Kemponia Bruce, 2004 (Crustacea: Decapoda: Palaemonidae)
Designation of a new genus Lipkemenes, with supplementary description and range extension of its type species, L. lanipes (Kemp, 1922) (Decapoda, Palaemonidae)
TLDR
A new pontoniine genus, Lipkemenes gen. nov. lanipes, is established for the ophiuroid-associated shrimp, Periclimenes lanipes Kemp, 1922, which is the only Indo-West Pacific pontonerine shrimp known to associate with an ophi Kuroid host.
Izucaris Masudai, New Genus, New Species (Decapoda: Caridea: Palaemonidae), a Sea Anemone Associate From Japan
TLDR
A new genus is proposed for Izucaris masudai, new species, a pontoniid shrimp associated with the sea anemone Nemanthus nitidus, Japan, distinguished by the rostrum overreaching the midlength level of the distal peduncular article of the antennule and the pterygostomian margin distinctly tapering anteriorly.
Palaemonella Hachijo, A New Species Of Shrimp (Crustacea : Decapoda : Palaemonidae) From A Submarine Cave In Southern Japan
Molecular phylogeny of hinge-beak shrimps (Decapoda: Caridea: Rhynchocinetes and Cinetorhynchus) and allies: a formal test of familiar and generic monophyly using a multilocus phylogeny
TLDR
These analyses showed that the superfamily Nematocarcinoidea, as currently accepted, is polyphyletic, and the two major clades recognized by the SATe-II analysis are clearly concordant with the genera Rhynchocinetes and Cinetorhynchus, which are currently recognized in the morphological-based classification (implicit phylogeny).
