One specimen of an un-described species of pontoniine shrimp of the genus Laomenes Clark, 1919, Laomenes albonigrus sp. nov., was collected from a crinoid host from Ashmore Reef, Western Australia, and is now described and illustrated. 

A sponge-associated species of the genus Nippontonia new to science is described from Semporna, Sabah, Malaysia. The only other species in the genus is also known to be a sponge-dweller. The new species can be distinguished from its con- gener by a suite of characters mainly of the anterior appendages.

A new species of crinoid associated Periclimenes, P. rincewindi sp. nov. is described from the Bay Islands (Honduras) in the Caribbean. The species associates with the swimming crinoid, Analcidometra armata and displays a unique colour pattern. Morphologically, the new species is closely related to the other known crinoid associates in the Caribbean, specifically Periclimenes crinoidalis, from ...

An unusual species of the genus Periclimenaeus Borradaile, 1915 (Crustacea: Decapoda: Palaemonidae Pontoniinae) from Heron Island, Queensland, Australia, collected by Dr Niel Bruce in 1979, is described and illustrated. Periclimenaeus denticulodigitus sp. nov., an ascidian associate was collected from coral reef at 7.0 m and presents some interesting new features. It increases to 17 the number ...

A new pontoniine shrimp species, Cuapetes yapiensis, from mangroves at Quamun, on Yap Island, Caroline Islands, is described and illustrated. Cuapetes yapiensis most closely resembles C. darwiniensis Bruce. Six species of Cuapetes are now known from the Caroline Islands.

The present study deals with four species of benthic deep-water caridean shrimps collected on the continental slope off southeastern Brazil, between 360 m and 900 m. The deepwater pandalid Bitias stocki Fransen, 1990, previously known only from a few localities in the eastern Atlantic, is reported for the first time from the western Atlantic (Brazil). The Brazilian material of B. stocki also re...

An undescribed species of pontoniine shrimp of the genus Nippontonia Bruce & Bauer, N. ashmoriensis sp. nov., collected from a sponge from Ashmore Reef, Western Australia, is described and illustrated. 

Recent phylogenetic work (Ashelby et al., 2012) has demonstrated the need for a fresh appraisal of the systematic status of some Palaemoninae genera. In the present contribution the accumulated morphological as well as molecular evidence is reviewed. The genera Palaemonetes, Exopalaemon and Coutierella are demonstrated to be junior synonyms of Palaemon, which now contains 83 species. As a resul...

A new species of pontoniine shrimp, Onycocaris maui sp. nov., from Maui Island, Hawai'i, is described and illustrated. A heterosexual pair were found in an intertidal Haliclona sponge. A member of the O. quadratophthalma species group, its relationships are discussed and a key provided for their identification.

A new coral-associated species of the genus Hamodactylus is described from Lembeh Strait, NE Sulawesi, Indonesia. The three other known species in the genus have been recorded in association with octocorals. The single ovigerous female specimen of the new species was collected from a scleractinian host. It can be easily separated from its congeners by the very long eyestalks and the chela of th...
