On Parathelphusa ceophallus spec. nov. (Crustacea: Decapoda: Brachyura: Parathelphiisidae) from Pulau Buton, Sulawesi Naturalis
Ng, P.K.L..
A new species of parathelphusid freshwater crab, Parathelphusa ceophallus, is described from Pulau Buton, a small island southeast of the island of Sulawesi in Indonesia. The species is differentiated from its allies in the P. celebensis complex by the form of its anterolateral margin, postorbital cristae, frontal median triangle, and male first pleopod.

First record of Calappoidea and Dromioidea from the Upper Cretaceous (Upper Maastrichtian) of NW Madagascar Naturalis
Garassino, Alessandro; Pasini, Giovanni.
The crustaceans from the marine Berivotra Formation, dated as late Cretaceous, from 50 km south of Mahajanga, Madagascar contains macrurans, brachyurans and thalassinideans. Two brachyuran families, Raninidae and Dynomenidae, were previously identified with the genera Notopocorystes, Caloxanthus, Titanocarcinus, Xanthosia, and Dromiopsis. Fragmentary material now also allows the recognition of Dromioidea, Calappoidea and Xanthoidea.

An interesting case of homonymy: Notopus de Haan, 1841 (Crustacea, Raninidae; Recent) and Notopus Leonardi, 1983 (ichnofossil; Devonian) Naturalis
Bakel, Barry W.M. van; Jagt, John W.M.; Fraaije, René H.B..
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].

Cylisticus convexus, een in Nederland zeldzame synantrope landpissebed (Crustacea: Isopoda: Oniscoidea) Naturalis
Berg, M.P.; Wijnhoven, H.; Tempelman, D..
Cylisticus convexus, a rare synanthropic woodlouse in The Netherlands (Crustacea: Isopoda: Cylisticidae) Until recently, the occurrence of Cylisticus convexus (De Geer, 1778) in the Netherlands was uncertain. The only certain old record dates from March 1927, when the species was collected at the coal-shed of the Zoological Museum at Amsterdam. During the last years, two specimens have been collected on semi-natural sites. Both were found on a dike, one near Everdingen, in the province of Gelderland, and one near Ritthem, in the province of Zeeland. These are the first records of C. convexus in the field. Yet the species certainly is very rare in The Netherlands. The most important morphological characteristics of the species are described and...

Palaemon vicinus spec. nov. (Crustacea: Decapoda: Palaemonidae), a new species of caridean shrimp from the tropical eastern Atlantic Naturalis
Ashelby, C.W..
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.

The recent species of Megabalanus (Cirripedia: Balanomorpha) with special emphasis on Balanus Tintinnabulum (Linnaeus) Sensu Lato Naturalis
Henry, D.P.; Mclaughlin, P.A..
Since Darwin's (1854) description of 11 varieties of Megabalanus tintinnabulum (Linnaeus) [as Balanus tintinnabulum], 26 Recent taxa have been assigned to the genus. In this review, two taxa confounded by Darwin are reestablished [i.e., M. crispatus (Schroter) and M. dorbignii (Chenu)]. M. antillensis (Pilsbry) and M. intermedius (Darwin) are placed in synonymy with M. tintinnabulum sensu stricto. M. galapaganus (Pilsbry) is synonymized with M. peninsularis (Pilsbry) and M. xishaensis Xianqui & Liu is considered a synonym of M. occator. Diagnoses and an illustrated key to the species are presented. Lectotypes are designated for M. tintinnabulum, M. crispatus, M. dorbignii, M. coccopoma (Darwin), M. spinosus (Chenu), M. validus (Darwin), and M. ajax...

Redescription of two species of Cymbasoma from southwest Britain and from Indonesia (Copepoda: Monstrileoida), with notes on taxonomy Naturalis
Suárez-Morales, E..
One of the main current problems in the taxonomy of the monstrilloid copepods is the lack of detailed descriptions. Most of these descriptions are poorly illustrated making the recognition of species even more difficult. Reexamination of specimens deposited in different museums of the world has vielded new taxa but also the opportunity of redescribing these species according to upgraded standards. Two species of Cymbasoma, one from southwest England and the other from the Java Sea are redescribed from the holotype specimens following upgraded standards. Both species are compared with related forms for the first time. The former species (C. striatus) has several interesting characters of which the most important is a fringe of striations covering about half...

Decapod crustaceans from the Oligocene of the Ligure Piemontese Basin, northern Italy Naturalis
Angeli, Antonio De; Marangon, Sergio.
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...

The fi rst Microcharon (Crustacea, Isopoda, Microparasellidae) from the Moroccan North Saharan Platform. Phylogeny, origin and palaeobiogeography Naturalis
Aït Boughrous, A.; Boulanouar, M.; Yacoubi, M.; Coineau, N..
The interstitial stygobites of the genus Microcharon (Crustacea, Isopoda, Microparasellidae) are highly diversified in Morocco, especially in the High Atlas. A new species from the North Saharan platform is described. Microcharon oubrahimae n. sp. is characterized by the original morphology of the first male pleopod which exhibits a concave inner margin of the distal part and a subdistal position of the armature. From a phylogenetic point of view, M. oubrahimae does not belong to the lineage which includes the Moroccan Atlasian species. In contrast, it belongs to the eastern- Mediterranean group of species. It is related to the species of the group M. orghidani-M. bureschi-M. phlegetonis from Romania and Bulgaria. The two-step model of colonization and...

Porcellium conspersum, een in Nederland zeer zeldzame landpissebed van vochtige bossen (Crustacea: Isopoda: Oniscoidea) Naturalis
Soesbergen, M..
The influence of recent inundations on the distribution pattern of the isopod Eluma purpurascens in the province of Zeeland (Crustacea: Isopoda: Oniscoidea) Small scale mapping of Eluma purpurascens Budde-Lund, 1885 in the province of Zeeland revealed a remarkable distribution pattern. The species proved to be absent in parts which have been inundated during and after the second world war. This study shows that for the interpretation of distribution patterns the history of the study area should be considered.

Interpreting ecology and physiology of fossil decapod crustaceans Naturalis
Feldmann, Rodney M..
Decapods are the most diverse and complex group of crustaceans, adapted for life in all parts of the marine environment, many aquatic habitats, and some terrestrial niches. With this diversity of life styles, a vast range of morphotypes of decapods has evolved, exploiting almost every imaginable variation in morphology of the complex exoskeleton that characterizes them. Many of the morphological variants are a response to exploiting a particular niche in which the organisms live or an adaptation to particular behavioral characteristics. Assessing the significance of morphological variation in the fossil record is challenging because of the taphonomic overprint that results in loss of soft tissue, preservation of partial remains of hard parts, and vastly...

Early Cretaceous decapod Crustacea from the Neuquén Basin, west-central Argentina Naturalis
Aguirre-Urreta, Maria Beatriz.
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.

Bladpootkreeften in Nederland, een overzicht (Crustacea: Branchiopoda: Phyllopoda) Naturalis
Soesbergen, M.P..
Vreemde levensvormen zoals trilobieten en degenkrabben hebben altijd al tot de verbeelding gesproken. In ons land hebben we de bladpootkreeften. Binnen deze groep zijn twee vormen te onderscheiden, vijf centimer grote trilobietachtige kreeften met een groot schild en slanke, kleurrijke garnaalachtige dieren, die met de buikzijde omhoog zwemmen. Ze zijn beide aangepast aan het leven in een bijzonder biotoop: tijdelijke watertjes, zoals karresporen en snel opdrogende poelen. Ze komen al 200 miljoen jaar in onveranderde vorm voor en behoren tot de oudst levende soorten op aarde.
