– Two new species of freshwater crabs in the genus Parathelphusa H. Milne Edwards, 1853, are described from Palawan Island in the Philippines. The new species are each easily distinguished from their closest congeners by characters of the male first pleopod, in conjunction with a unique combination of other morphological characters. A key to the Parathelphusa species of the Philippines is provi...

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 ...

Two specimens representing two hippolytid genera were sampled recently from the Coral Seamount, southwest Indian Ocean, at 732 m water depth. Lebbeus ketophilos sp. nov. and Eualus oreios sp. nov. are described and illustrated and their morphologies are compared with those of previously described species. The new species are closest in morphology to L. indicus Holthuis, 1947 and E. kinzeri Tief...

A new porcellanid crab, Lissoporcellana demani n. sp. is described based on material from the Beibu Bay in the northern South China Sea. The new species can be distinguished from other congeners by the shape of rostrum, form of fixed finger of smaller cheliped and armature of lateral margins of carapace. The poorly known species L. streptochiroides (Johnson, 1970), which resembles L. demani n. ...

With the birth of next-generation sequencing (NGS) technology, genomic data in public databases have increased exponentially. Unfortunately, exogenous contamination or intracellular parasite sequences assemblies could confuse analysis. Meanwhile, they can provide a valuable resource for studies host-microbe interactions. Here, we used strategy based on DNA barcodes to scan protistan GenBank WGS...

This article provides an overview of our understanding of life-long neurogenesis in the decapod crustacean brain, where the proliferation of sensory and interneurons is controlled by many of the same factors as is neurogenesis in the mammalian brain. The relative simplicity, spatial organization and accessibility of the crustacean brain provide opportunities to examine specific neuronal pathway...

A new species of pontoniine shrimp, Periclimenes nevillei, from Espiritu Santo, Vanuatu, is described and illustrated. The species is an associate of an antipatharian host, Cirripathes sp. A member of the Periclimenes brevicarpalis species group, to which a key is provided, it most closely resembles Periclimenes albolineatus Bruce & Coombes, 1997.

New records are presented for the caridean shrimp family Processidae in Indo-West and East Pacific waters, based mainly on recently collected material. These records highlight that many processid species may be relatively widespread, although the distribution of some species remains imperfectly known. The colour pattern of several species is here documented for the first time, showing its poten...

Eleven species of calappid and leucosiid crabs were identified from by-catch landed by trawlers at four fishing ports in Kerala, India that were surveyed in 2007 and supplemented by material obtained in January 2013. Four species are reported for the first time from India, six are new records for Kerala. The status of Mursia bicristimana Alcock & Anderson, 1894, is clarified and the species red...
