A new genus and species of potamid cavernicolous crab, Thampramon tonvuthi sp. nov., is described from Thailand. While superficially similar to Tiwaripotamon Bott, 1970, Phaibulamon Ng, 1992, and Nemoron Ng, 1996, the new genus possesses a unique combination of morphological characters including a distinctive carapace form, possession of a relatively long third maxilliped exopod, long ambulator...

The pagurid hermit crab genus Trichopagurus de Saint Laurent, 1968 is currently represented by three shallow water spe- cies from the tropical Indo-West Pacific region. In this paper, three species of the genus, including one new species, are reported. Trichopagurus tenuidactylus n. sp. is described on the basis of a single ovigerous female from the Bohol Sea, the Philippines, and compared with...

The present study describes the reproductive biology, population structure and life history traits of the abundant intertidal crab Xantho poressa. Between March 2007 and April 2008, a total of 1918 individuals were collected in Corrales de Rota (SW Spain), a human-modified intertidal habitat characterized by an artificial high complexity. Suitable refuges for crabs (cobbles and boulders) are ve...

Linear leak currents have been implicated in the regulation of neuronal excitability, generation of neuronal and network oscillations, and network state transitions. Yet, few studies have directly tested the dependence of network oscillations on leak currents or explored the role of leak currents on network activity. In the oscillatory pyloric network of decapod crustaceans neuromodulatory inpu...

A new species of the genus Calliaxina Ngoc-Ho, 2003, Calliaxina xishaensissp. n., collected from the South China Sea is described and illustrated. It is distinguishable from Calliaxina thomassini Ngoc-Ho, 2014 by having the rostrum broadly triangular with pointed tip and is distinguishable from Calliaxina novaebritanniae (Borradaile, 1900) and Calliax punica (de Saint Laurent & Manning, 1982) b...

A small collection of 159 specimens of stenopodidean shrimps from New Caledonian waters has been studied and found to represent 13 species in 6 genera, adding 8 new species of stenopodideans to the Southwest Pacific fauna. Two new species are recognized, Richardina crosnieri n. sp. and Spongiocaris neocaledonensis n. sp. Two species of Odontozona are redescribed. Illustrations are provided for ...

The species-group name Pagurus longitarsus was proposed by De Haan (1849: 211, pl. 50, fig. 3) for a species of hermit crab collected from Japan (see Yamaguchi & Baba 1993: 272, 273). Dana (1852b: 464) transferred Pagurus longitarsus to the genus Clibanarius Dana, 1852 (first established in Dana 1852a). Dana (1852b: 464) also suggested that Pagurus longitarsus De Haan, 1849, and Pagurus asper H...

A recent descriptive account based on material in the Senckenberg Forschungsinstitut und Naturmuseum included descriptions of two new fossorial axiidean shrimp from the northeastern Gulf of Mexico. Both were based on fragmentary immature specimens, and the accompanying illustrations appeared to potentially represent known species. The types were obtained on loan for study in each of our labs. I...

Two new Chinese genera and species of freshwater crabs, Yuexipotamon arcophallus, new genus, new species, and Minutomon shanweiense, new genus, new species, are described from Zhaoqing City and Shanwei City, respectively. The former is superficially closest to Huananpotamon Dai & Ng, 1994, while the latter resembles Sinopotamon Bott, 1967, and Mediapotamon Dai, 1995. The two new genera, however...

Two new species of the callianassid ghost shrimp are described and illustrated on the basis of specimens from the Ryukyu Islands, Japan. These are provisionally assigned to the genus Cheramus Spence Bate, 1888, and appear closest to Callianassa acutirostella Sakai, 1988, also provisionally transferred to Cheramus herewith. These three species can be differentiated by characters of the telson, t...
