| The family Galatheidae is among the most diverse families of anomuran decapod crustaceans, and the South-West Pacific is a biodiversity hot spot for these squat lobsters. Attempts to clarify the taxonomic and evolutionary relationships of the Galatheidae on the basis of morphological and molecular data have revealed the existence of several cryptic species, differentiated only by subtle morphological characters. Despite these efforts, however, relationships among genera are poorly understood, and the family is in need of a detailed systematic review. In this study, we assess material collected in different surveys conducted in the Solomon Islands, as well as comparative material from the Fiji Islands, by examining both the morphology of the specimens and... |

| The identity and taxonomy of 21 species of Thai freshwater crabs described between 1869 and 1992 of the families Potamidae (Potamon kanchanaburiense Naiyanetr, 1992; P. maesotense Naiyanetr, 1992; P. boonyaratae (Naiyanetr, 1987); Potamon phuphanense Naiyanetr, 1992; P. erawanense Naiyanetr, 1992; P. maehongsonense Naiyanetr, 1992; P. yotdomense (Naiyanetr, 1984); Dromothelphusa phrae (Naiyanetr, 1984); Larnaudia chaiyaphumi Naiyanetr, 1982; Thaipotamon siamense (A. Milne Edwards, 1869); T. smitinandi (Naiyanetr & Türkay, 1984); Thaiphusa sirikit (Naiyanetr, 1992); Demanietta tritrungense (Naiyanetr, 1986)), Gecarcinucidae (Phricotelphusa ranongi Naiyanetr, 1982; Thaksinthelphusa yongchindaratae (Naiyanetr, 1988)) and Parathelphusidae... |

| On several occasions, shrimps belonging to a new species of the genus Typhlatya were collected in a cave in the province of Castellón, Spain. This is the first record of the genus in the Iberian Peninsula. The species is described and the validity, distribution, and zoogeography of the genus, as well as the status of the genus Spelaeocaris, are discussed. Former models for the evolution of the genus Typhlatya and its genus group are reviewed, as well as the system of inner classification of the Atyidae and its biogeographical meaning. For the age and evolution of the genus we developed a new model based on vicariance principles that involves further evolution of each species after the disruption of the ancestral range. This allows new estimations for the... |

| Os anomuros de Aeglidae são restritos às águas doces da região subtropical e temperada da América do Sul. Entre as mais de 60 espécies conhecidas da ciência, algumas são simpátricas, destacando-se Aegla camargoi Buckup & Rossi, 1977 e Aegla leptodactyla Buckup & Rossi, 1977, que ocorrem na região serrana do Rio Grande do Sul, Brasil. A interação das duas espécies simpátricas, especificamente o compartilhamento dos recursos alimentares, ainda permanece desconhecido. Nesta investigação, a alimentação natural, a largura e a sobreposição de nicho trófico das espécies são estudadas e comparadas. Os animais foram coletados sazonalmente, em intervalos de 6 por 24 horas. Em laboratório, foi analisado o conteúdo estomacal, utilizando as técnicas do... |

| 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.... |

| A new species of freshwater palaemonid prawn, Macrobrachium oxyphilus spec, nov., is described from highly acidic blackwaters in a peat swamp forest in Selangor, Peninsular Malaysia. The species differs from its nearest congener, M. trompii (de Man, 1898), in having proportionately smaller eyes, shorter scaphocerites, a lesser number of ventral rostral teeth, a more inflated carapace, and less pubescent and more spiniferous chelipeds. |

| Libinia spinosa H. Milne Edwards in Guérin, 1832 and L. ferreirae Brito Capello, 1871, inhabit very similar environments, and their geographic and bathymetric distributions overlap for about 3000 km along the southwestern Atlantic. Both species are commonly caught in the same haul and differentiating between them can often be difficult. Traditionally, morphological differentiation between L. spinosa and L. ferreirae has been based exclusively on the number of spines along the median, longitudinal line of the carapace and the development of a process at the anterolateral angle of the basal segment of the antenna. Because Libinia spinosa and L. ferreirae share similar numbers of median spines (7 and 6, respectively), and the number of median spines of the... |

| Two new species of sesarmid crabs are described from the mangroves of Timika in Papua (= Irian Jaya), Indonesia. Haberma kamora spec. nov. is the second species in the genus described from Singapore, differing from the type species in the form of its male first pleopods and possessing relatively more slender ambulatory legs. Parasesarma charis spec. nov. resembles P. erythrodactyla, P. tripectinis and to some extent, P. lepidum, but has different ambulatory leg proportions and a distinctive male first pleopod structure. Parasesarma acis Davie, 1993, is regarded as a junior synonym of P. tripectinis Shen, 1940. |
