Patagurus is characterized by a subtriangular, vault- ed, calcified carapace, with large, wing-like lateral processes, and is closely related to two other atypical pagurid genera, Porcellanopagurus Filhol, 1885 and Solitariopagurus Türkay, 1986. The broad, fully calcified carapace, calcified bran- chiostegites, as well as broad and rigidly articulated thoracic sternites make this remarkable animal one of the most crab- like hermit crabs. Patagurus rex carries small bivalve shells to protect its greatly reduced pleon. Carcinization pathways among asymmetrical hermit crabs and other anomurans are briefly reviewed and discussed. Key words: Decapoda, Paguridae, hermit crab, deep-water, carcinization, Porcellanopagurus, Solitariopagurus, Indo- West Pacific Introduction Carcinization, or development of a crab-like body plan, is a term describing an important evolutionary tendency within the large crustacean order Decapoda. The term “carcinization” was coined by Borradaile (1916) with reference to crab-like modifications in the hermit crab genus Porcellanopagurus Filhol, 1885 (Paguridae). -
How to Become a Crab: Phenotypic Constraints on a Recurring Body Plan

For over 140 years, convergent evolution of the crab-like body plan (with a wide and flattened shape, and a bent abdomen) at least five times in decapod crustaceans has been known as ‘carcinization’. The repeated loss of this body plan has been identified as ‘decarcinization’. We offer phylogenetic strategies to include poorly known groups, and direct evidence from fossils, that will resolve the pattern of crab evolution and the degree of phenotypic variation within crabs. Proposed ecological advantages of the crab body are summarized into a hypothesis of phenotypic integration suggesting correlated evolution of the carapace shape and abdomen. Our premise provides fertile ground for future studies of the genomic and developmental basis, and the predictability, of the crab-like body form.

Die Magenstrukturen Der Brachyura (Crustacea, Decapoda): Morphologie Und Phylogenetische Bedeutung

November 2002 Wissenschaft hat etwas Faszinierendes an sich. So eine geringfügige Investition an Fakten liefert so einen reichen Ertrag an Voraussagen. Mark Twain • Keywords: Brachyura, phylogeny, foregut-ossicles, fossil record • Schlagworte: Brachyura, Phylogenie, Magenossikel, Fossilbericht Abstract Within the Decapoda the taxon Brachyura is the species-richest taxon with up to 10000 species. The phylogeny of the Brachyura has been discussed based on morphological and molecular investigations since more than a century. The investigation of the foregut-ossicles and gastric-teeth of 66 brachyuran species, is a new approach to answer important phylogenetic questions. Using a specific staining pigment Alizarin Red S, six new described foregut-ossicles are added to an existing nomenclature. As a result of this method the presence of 41 foregut-ossicles is proposed for the ground pattern of the Brachyura. The cladistic analysis supports a monophyletic origin of the Brachyura including the Dromiidae and the Raninidae. The taxa Podotremata and Heterotremata, postulated as monophyletic by Guinot (1977, 1978), are not supported in the present study. The Dromiidae and Raninidae, which are placed within the Podotremata sensu Guinot, are closer related to the “higher crabs”. -

Question Écrite De Mme TEVAHITUA Relative À L

À Monsieur Édouard FRITCH Président de la Polynésie française Objet : Usucapion par le C.A.MI.CA des îlots de TEMATAGI, VANAVANA, MARIA, MATURAI-VAVAO, VAHANGA, TENARARO et TENANT A ou TENARUNGA En 1836, Edward RUSSELL, un lord et officier de la marine britannique décide de baptiser les îles qu’il observe alors depuis son navire militaire. Ces quatre îlots situés dans l’archipel des Tuamotu à 245 km de l’archipel des Gambier porteront, par le fait du prince, le nom de son navire, l’Actéon. Ainsi ces îles seront désormais connues sous le nom de groupe Actéon ou îles du groupe Actéon. Les premiers occupants de ces terres n’ont pas attendu le passage furtif de M. RUSSELL pour nommer ces quatre îlots qui portent en réalité depuis des temps immémoriaux les noms de TENARARO, TENARUNGA ou TENANT A, VAHANGA et MATURAI-VAVAO. Ces toponymes pau ’motu conservés dans la langue de leurs occupants originels sont la preuve irréfutable que ces terres sont originellement la propriété exclusive du peuple Pau ’motu premier occupant de cet archipel. A cet égard, il convient de rappeler, et ce n’est que leur rendre justice, que ce sont les mêmes descendants du peuple Pau ’motu, qui plantèrent et exploitèrent lesdits motu, sous la férule du père VALLONS dans la seconde moitié du XXerae siècle. -
Par Jacques FOREST. La Description De Porcellanopagurus Est
— 181 — CONTRIBUTION A L'ÉTUDE DU GENRE PORCELLANOPAGURUS FlLHOL (PAGURIDAE) [suite et fin]. II. — REMARQUES SYSTÉMATIQUES ET BIOLOGIQUES. Par Jacques FOREST. La description de Porcellanopagurus edwardsi par FILHOL est imprécise et il est probable que l'auteur n'a examiné que le plus grand exemplaire — d'ailleurs mutilé — qu'il avait entre les mains. Elle comporte une erreur importante : parlant de l'abdomen, FILHOL écrit « il porte à sa partie antérieure une paire de pattes courtes et grêles », or il s'agit, en l'occurrence, de la dernière paire de péreiopodes, séparée du reste de la région thoracique par un profond sillon. Les figures qui illustrent le texte original sont aussi fort inexactes : le dessin d'ensemble (pl. 49, fig. 4) a été exécuté d'après le plus grand exemplaire, lui aussi, mais, en réalité, le rostre est moins long, la concavité qui le sépare du premier lobe latéral beaucoup plus pro fonde, et ce premier lobe plus saillant. D'autre part la forme du bord antéro-latéral de la carapace est assez variable d'un individu à un autre, comme le montre notre figure 2, sur laquelle le spécimen dessiné par FILHOL est situé à l'extrême droite. Autre erreur : les chélipèdes sont figurés égaux 1, or celui de droite est toujours de forme différente et beaucoup plus fort que le gauche. Le texte de la description ne mentionnant pas la dissymétrie de ces appendices, certains auteurs se sont uniquement basés sur les illustrations qui l'accompagnaient. Mais il existe d'autres travaux de FILHOL qui auraient montré qu'il s'agissait bien d'une erreur de représentation, sans même qu'on s'en rapportât au type. -

Current statusof the endangeredTuamotu Sandpiper or Titi Prosobonia cancellataand recommendedactions for its recovery.Wader StudyGroup Bull. 105: 93-100. The TuamotuSandpiper or Titi is the only survivingmember of the Tribe Prosoboniiniand is confinedto easternPolynesia. Formerly distributedthroughout the Tuamotu Archipelago,it has been decimatedby mammalianpredators which now occuron nearlyall atollsof the archipelago.Isolated sandpiper populations are currentlyknown from only four uninhabitedatolls in the Tuamotu.Only two of theseare currentlyfree of mammalianpredators, such as cats and rats, and the risks of rat invasionon themare high. This paper outlines tasksnecessary in the shortterm (within five years)to securethe species,together with longerterm actions neededfor its recovery.Short-term actions include increasing the securityof existingpopulations, surveying for otherpotential populations, eradicating mammalian predators on key atolls,monitoring key populations, and preparing a recovery plan for the species. Longer term actions necessaryfor recovery include reintroductions,advocacy and research programmes. INTRODUCTION ecologyof the TuamotuSandpiper as completelyas is cur- rently known, assessesthe -

Evolutionary origins of novel forms are often obscure because early and transitional fossils tend to be rare, poorly preserved, or lack proper phylogenetic contexts. We describe a new, exceptionally preserved enigmatic crab from the mid-Cretaceous of Colombia and the United States, whose completeness illuminates the early disparity of the group and the origins of novel forms. Its large and unprotected compound eyes, small fusiform body, and leg-like mouthparts suggest larval trait retention into adulthood via heterochronic development (pedomorphosis), while its large oar-like legs represent the earliest known adaptations in crabs for active swimming. Our phylogenetic Downloaded from analyses, including representatives of all major lineages of fossil and extant crabs, challenge conventional views of their evolution by revealing multiple convergent losses of a typical “crab-like” body plan since the Early Cretaceous. These parallel morphological transformations -

([email protected]) Abstract The diagnosis of the recently described hermit crab genus Catapaguropsis Lemaitre & McLaughhn, 2006 is emended to accommodate a second distinctive new species, Catapaguropsis brucei n. sp., which does not exhibit the sexual dimor- phism described for the type species, C queenslandica Lemaitre & McLaughlin, 2006. Catapaguropsis brucei n. sp. is characterized by the marked reduction, in both sexes, of the posterior portions of the pleons, uropods, and telsons that are encased by cnidarians. In addition to the description and illustrations, this new species is compared and contrasted with species of other pagurid genera that occupy atypical carcinoecia. Key words: Crustacea, Decapoda, Paguridae, emended Catapaguropsis, new species, unique carcinoecia. South China Sea Introduction Catapaguropsis Lemaitre & McLaughlin, 2006 was proposed for two specimens that shared characters with Catapagurus A. Milne-Edwards, 1880 and Pteropagurus McLaughlin & Rahayu, 2006, but were clearly dis- tinct from both. However, the male and female exhibited marked sexual dimorphism, with the female resem- bling species of Catapagurus and the male more similar to species of Pteropagurus.
