| In addition to a taxonomic review of the whole order Thermosbaenacea, the general morphology and chaetotaxy are discussed in detail. Due to the results of cuticular staining, and through the study of specimens with SEM techniques also, corrections to earlier interpretations could be made. A chaetotaxic classification, modified after the one of Watling (1989), is presented. In the taxonomic part 34 species are recognized, belonging to seven genera (one new), four families (one new). The examination of adult material of the type species of Monodella, i.e., Monodella stygicola Ruffo, 1949, warranted the creation of Tethysbaena gen. nov., to comprise all other taxa previously included in Monodella. Transferred to Tethysbaena are: M. argentarii Stella, 1951; M.... |

| We record the discovery of Coleia Broderip (Eryonoidea: Coleiidae) from the Nakatsuka Formation, Mine Group, Upper Triassic of Japan. The specimens were collected from shales exposed at Tsubuta, Sanyo-cho (Yamaguchi Prefecture). Coleia co-occurs there with fragments of a penaeoid, bivalves, Halobia spp., ammonites, and plants. |

| The West African marine brachyuran crab fauna, comprising 218 named species in 120 genera and 26 familes, is surveyed. Sixteen new genera and 24 new species are recognized. Synonymies are updated for the tropical species, and all 300 + Eastern Atlantic species are listed. Original references and synonymies are provided for all 146 Eastern Atlantic genera. Synonymies have been compiled for all 36 currently recognized families of marine crabs. Twenty-nine families are represented in the Eastern Atlantic fauna. One family, Hexapodidae Miers, 1886, and one subfamily, Camptandriinae Stimpson, 1858 (Ocypodidae) are revised at the generic level. The genera Liocarcinus Stimpson, 1871 (Portunidae), Machaerus Leach, 1818 (Goneplacidae), and Lambdophallus Alcock,... |

| The amphipod Echinogammarus stoerensis not extinct in The Netherlands (Crustacea: Amphipoda: Gammaridea) The gammaridean amphipod Echinogammarus stoerensis has never been a common species in the Netherlands, due to the scarcity of suitable habitats. It is typically found under boulders on a gravelly substrate, where a freshwater flow occurs over the littoral zone. As a result of reinforcement of sea dykes, the typical habitat disappeared from The Netherlands. However, E. stoerensis proves to survive in less suited substrates with more silt, and freshwater supply only from rain. |

| Cuipora janaina gen. n., sp. n., and Cyclopina caiala sp. n. are described from the interstitial water of a sandy beach in Salvador, Bahia (Brazil). Cuipora is distinguished from all other genera of the subfamily Cyclopininae in having the endopodite of legs 1-4 2-segmented and the terminal segment armed with 4 setae. Cuipora is compared to Erythropolites Huys & Boxshall, 1990, Herbstina Huys & Boxshall, 1990, and Cyclopina Claus, 1862, with which it has most morphological similarities. Cyclopina caiala sp. n. is distinguished by the structure of the leg 5 of the male and female and by a particular combination of characters of the mouthparts. Taxonomical problems involving Cylopina mediterranea Steuer, 1940 are discussed. |

| 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... |

| Carefully collected molecular data and rigorous analyses are revolutionizing today’s phylogenetic studies. Although molecular data have been used to estimate various invertebrate phylogenies lor more than a decade, this study is the first survey of different regions of mitochondrial DNA in isopod crustaceans assessing sequence divergence and hence the usefulness of these regions to infer phylogeny at different hierarchical levels. 1 evaluate three loci from the mitochondrial genome (two ribosomal RNAs (12S, 16S) and one protein-coding (COI)) for their appropriateness in inferring isopod phylogeny at the suborder level and below. The patterns are similar for all three loci with the most speciose suborders of isopods also having the most divergent... |

| Among 26 species of Antarctic Cumacea sampled during the southern summer 1989/90 from benthic habitats in the Weddell Sea, four are described as new to science: Campylaspis ledoyeri spec. nov., Hemilamprops bacescui spec. nov., Paralamprops racovitzai spec. nov., and Leptostylis weddelli spec. nov. Detailed descriptions are given for the previously unknown or undescribed sex in seven species: Cyclaspis gigas Zimmer, 1907, Procampylaspis compressa Zimmer, 1907, Paralamprops asper Zimmer, 1907, P. mawsoni (Hale, 1937), Diastylis anderssoni armata Ledoyer, 1993, D. mawsoni Calman, 1918, and Leptostylis antipus Zimmer, 1907. Previous descriptions are supplemented by additional morphological data on 14 species: Cyclaspis gigas, Vaunthompsonia inermis Zimmer,... |

| Two new stygobiont amphipods are described from anchialine caves located in the Jaragua region (Pedernales Prov., Dominican Republic, Hispaniola). Ottenwalderia kymbalion gen. et sp. nov. is the first lysianassoid known to have penetrated into completely fresh waters, and the fourth colonizing hypogean habitats. Bahadzia jaraguensis sp. nov. is the second representative of this West Indian thalasso-stygobiont genus to be reported from fresh waters; it exhibits the most troglomorphic aspect (i.e. elongation of first antennae and sixth pereiopods) recorded for the genus. Its diagnosis is complemented with a key to the species of the genus Bahadzia. The in situ swimming behaviour of both taxa is briefly described. It is postulated that both amphipods share a... |

| Upper Cretaceous strata in the type area of the Maastrichtian Stage (SE Netherlands, NE Belgium) have yielded comparatively abundant and diverse raninid assemblages (Collins et al., 1995; Fraaye & van Bakel, 1998). To date, seven species are known: Eumorphocorystes sculptus, Pseudoraninella muelleri, Lyreidina pyriformis, Raninoides? quadrispinosus, Raniliformis chevrona, Raniliformis prebaltica and Raniliformis occlusa. These occur mainly from the upper portion of the Maastricht Formation [Emael, Nekum and Meerssen members, Belemnitella junior and Belemnella (Neobelemnella) kazimiroviensis biozones]. |
