| Marine deposits of the Neuquén Basin of west-central Argentina (southern South America) are richly fossiliferous; its Mesozoic invertebrate faunas, represented mostly by molluscs, have been extensively studied since the nineteenth century. However, Early Cretaceous decapod crustaceans are far less known, although part of the systematic framework has been published (Aguirre-Urreta, 1989). The aim of the present note is to provide updated information based on ongoing research into the systematics and taphonomy of this crustacean group in the Neuquén Basin. |

| The cyclodorippoid crabs from the Philippines collected by the PANGLAO 2004-2005 and AURORA 2007 expeditions are reported. Five species of Cyclodorippidae are reported: Corycodus mina x sp. nov., Ketamia depressa (Ihle, 1916), Krangalangia spinosa (Zarenkov, 1970), Tymolus brucei Tavares, 1991, and Xeinostoma sakaii Tavares, 1993. Corycodus minax is the second species of the genus to be recorded from the Philippines and is most similar to C. merweae Tavares, 1993, from South Africa. Krangalangia spinosa is reported for the first time from the Philippines. Sexual dimorphism in the length of the walking legs (pereopods 2 and 3) is reported for Tymolus brucei and may be a general feature of cyclodorippoids. One new species of Cymonomidae, Cymonomus liui sp.... |

| Lithologically, the decapod-bearing levels of Rupelian (Oligocene) age in the Ligure Piemontese Basin, are characterized by an alternation of greyish blue marls with nodular elements and silt-rich, occasionally sandy, marls. The fossil studied for the present note have been collected mainly from pebbles or nodules which were eroded out of the higher levels exposed of this sedimentary complex, referred to as the ‘Formazione di Molare’. These levels overli the ‘Formazioni continentali delle Brecce di Costa Cravara e Pianfolco’, studied by Charrier et al. (1964) and dated as Early Rupelian. The levels yielding brachyuran fossils were attributed by Allasinaz (1987) to the transition between the ‘Formazione di Molare’ and the overlying ‘Marne di Rigoroso’, and... |

| Two new species of infaunal decapod crustaceans are described based on material collected in Bahía Málaga, Pacific coast of Colombia, in 2009. The mud-shrimp Axianassa darrylfelderi sp. nov. (Axianassidae) appears to be most closely related to A. australis Rodrigues & Shimizu, 1992, A. canalis Kensley & Heard, 1990, and A. jamaicensis Kensley & Heard, 1990. The new species may be distinguished from each of them by a combination of morphological features, mainly on the uropodal exopod, antennal acicle, third maxilliped and first pleonite. The shrimp Leptalpheus canterakintzi sp. nov. (Alpheidae), associated with burrows of A. darrylfelderi sp. nov., undoubtedly represents the eastern Pacific sister species of the western Atlantic L. axianassae... |

| A new species of Palaemon, P. vicinus spec. nov., is described from the tropical eastern Atlantic. The new species is very close to P. elegans Rathke, 1837, under which name it was previously recorded from West Africa. Palaemon vicinus spec. nov. is easily separated from P. elegans by possessing a small tooth on the fifth abdominal pleuron (quadrate in P. elegans) and by having 2-3 rows of setae in the grooming brush of the fifth pereiopod (4-5 in P. elegans). The discovery of the new species amongst material identified as P. elegans further highlights the need to reassess species level characters in the genus Palaemon. |

| Gastropod shells occupied by hermit crabs are an important attachment substrate for epifauna, and these shells are often damaged. The present study aimed to characterize the epibionts and extent of damage for gastropod shells occupied by the hermit crab Loxopagurus loxochelis (Moreira, 1901). Samples were collected monthly over a period of one year (from July 2002 through June 2003), in the Caraguatatuba and Ubatuba regions, on the northern coast of São Paulo, Brazil. The sampling was performed using a fishing boat equipped with double-rig nets. The shells were identified and weighed. Loxopagurus loxochelis occupied 14 gastropod shell species in Caraguatatuba and five in Ubatuba. In the two areas, approximately 55% of these gastropod shells bore epibionts,... |

| The Brachyura collected on the continental shelf of Northern and Northeastern Brazil understood between the latitudes 4º27'N and 3º43'S and the longitudes of 50º00'W-38º00'W, were represented by 133 species, 79 genera and 15 families. The studied material, belongs to the carcinological collection of the Department of Oceanography of University Federal of Pernambuco. The informations obtained in relation to the areas in which these species are found, were gathered from the carcinological files cited above and bibliographic rcferences published until 1991. The majority of the species (125) was found exclusively in the western Atlantic, except three Anfi-Atlantics, two Anfi-Americans, two Circuntropicals and one Indo-Pacific. With regards to the latitude, 11... |

| Abstract: This study evaluated the relationships between environmental factors and the spatio-temporal distribution of H. pudibundus, with the hypothesis of differential occupation in coastal areas of southeastern Brazil. The samplings took place monthly in January-December 2000 period, along nine transects from 2 to 40 m of depth, in Ubatuba region, northern coast of São Paulo. We collected 1808 individuals of H. pudibundus. The highest abundance was recorded in winter in the transects 10-25 m deep. Abundance was positively correlated with organic matter content and texture sediment (phi values). With the retreat of the South Atlantic Central Water (SACW) in autumn and winter, the sediment swirls, suspending the detritivore and filter-feeding macrofauna,... |

| Studies on the occurrence, temporal distribution and nychthemeral variation of Macrobrachium amazonicum (Heller, 1862) were undertaken in Leopoldo's Inlet, upper Paraná River, Porto Rico, Paraná, Brazil. Seventeen thousand and sixty specimens (11,786 larvae and 5,274 juveniles) were captured with a conicalcylindrical plankton net of mesh 0.5mm in monthly samples between February 1991 and February 1992. Results show that the greatest densities of larvae (301.83 larvae/10m³) and juveniles (168.8/10m³) of this species were caught in December 1991. Largest captures were made during the night. With regard to abiotic factors water temperature ranged from 20º to 30ºC, pH ranged from 5.66 to 7.37 and electric conductivity ranged from 51.83 to 65.33µS/cm.... |

| The trembling of legs followed by increasing paralysis and eventual death, were recorded on specimens of the above sp from Sete region. EM studies of tissue showed paraspherical bodies measuring approx 61 nm with a size range of 58-65 nm. By experimentally infecting specimens with a purified viral suspension the following pathogenesis was observed: in greater than 60 per cent of the specimens, trembling of the legs began within 6 days, growing very pronounced on the 8th day, leading to a general paralysis and 9 days after the infection a mortality rate of 70-80 per cent was recorded. The following characteristics of the virus are noted: its cytoplasmic localisation, paraspherical form, size ranging from 60-70 nm and the absence of an envelope. Considering... |
