| 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.... |

| A new alpheid shrimp, Thuylamea camelus gen. nov. & spec. nov., from Dong Hoa, a coastal community of Can Gio district, and northwest of Vung Tau (Cap St. Jacques), Vietnam, is described and illustrated. The new genus appears not to be closely related to any of the previously described genera. It has the postero-dorsal margin of the carapace armed with two high and short crests which are slightly outward inclined and directed backward, and between these crests with a low but distinct conical spine, and an elevated conical boss in the anterior median area slightly behind the anterior margin of the first abdominal somite. |

| A phylogenetic analysis was conducted including representatives from all recognized extant and extinct families of the Xanthoidea sensu lato, resulting in one new family, Hypothalassiidae. Four xanthoid families are elevated to superfamily status, resulting in Carpilioidea, Pilumnoidoidea, Eriphioidea, Progeryonoidea, and Goneplacoidea, and numerous subfamilies are elevated to family status. The Mathildellidae is moved from the Goneplacidae to the Portunoidea. Diagnoses for all superfamilies and families discussed herein are provided, embracing characters typically used by biologists as well as readily fossilized features of the dorsal carapace, sternum, abdomen, and chelipeds. All genera known from the fossil record at one time referred to the Xanthidae... |

| A new genus and species of parasitic copepod (Clausiidae), Spionicola mystaceus, associated with the polychaete Dipolydora armata (Spionidae) is described and figured. The new copepod has an elongate body, 5-segmented antennule, 2-segmented rami on legs 1 and 2, 2 spines representing leg 3, no leg 4, leg 5 well developed and reduced armature elements on feeding limbs. The host is a mollusk-shell borer, collected off São Sebastião Island, State of São Paulo, Brazil. |

| Many papers on the taxonomy of fossil crustaceans are often based upon poorly preserved material and/or specimens that have been insufficiently prepared. The purpose of the present note is to outline some preparation methods that are applied in our (J.S.H. Collins and S.L.J.) ongoing studies of anomuran and brachyuran decapods from the Middle Danian limestones at Fakse quarry (Denmark), which have greatly enhanced the quality of our material. The techniques briefly outlined here involve: 1 – staining method; 2 – water blasting (as a cleaning tool in preparation of fossils); and 3 – negative preparation (with acid). Some of these techniques will have wide applications in other fields of paleontological research. |

| A specimen of a monstrilloid copepod collected by the U.S. Fisheries Steamer “Albatross“ in the Sulu Sea, west coast of Mindanao, Philippines, and deposited in the U.S. National Museum of Natural History, was taxonomically restudied. The specimen had been originally identified as a male of Monstrilla serricornis Sars by C.B. Wilson. Reexamination revealed that the specimen represents a new species of the genus Cymbasoma, C. mcalicei. This species can be distinguished by its body proportions and body size, but mainly by the structure of the genital lappets, which have a serrated posterior margin unique in the genus. This is the seventh species of Cymbasoma reported from East or Southeast Asia. |

| A new species of porcellanid crab, Polyonyx vermicola, belonging to the P. sinensis group is described from Selangor, Peninsular Malaysia. The species is an obligate commensal of tubes of the chaetopterid worm Sasekumaria selangora Rullier, 1976 (Polychaeta). Polyonyx vermicola is differentiated from all congeners by its small size, possessing a more rectangular carapace, proportionately longer carpus on the larger cheliped, strongly gaping cheliped fingers, the tips of which are turned outwards, the outer surface of each cheliped fingers lined with a row of small granules, and having the ventral margin of the third ambulatory propodus armed with strong spinules. |
