A collection of Thalassinidea, Anomura and Brachyura (Crustacea: Decapoda) from the Kimberley region of Northwestern Australia Naturalis
Morgan, G.J..
One hundred and five species of thalassinidean, anomuran and brachyuran decapod crustaceans are recorded from a 1988 collecting expedition to the Kimberley region of northwestern Australia. An additional 70 species are recorded from the literature. One new species of pagurid hermit crab and a new species of xanthid crab are described.

Carcinization in the Anomura – fact or fiction? I. Evidence from adult morphology Naturalis
McLaughlin, Patsy A.; Lemaitre, Rafael.
Carcinization, or the process of becoming a crab, has been, and continues to be, a focal point of anomuran evolutionary hypotheses. Traditional examples of carcinization in the Anomura are most celebrated among hermit crabs but certainly are not limited to this group. Carcinization, if it has occurred, has done so independently in all major anomuran taxa. In this critique, the traditional examples of carcinization in the Anomura are reviewed and more modern variations on the theme assessed. Potential pathways of carcinization are examined from perspectives of adult morphology in the Paguroidea, Galatheoidea, Hippoidea and Lomoidea, with emphasis on the Paguroidea. Specific attention is given to the theoretical transformation of a hermit crab-like body form...

Carcinization in the Anomura – fact or fiction? II. Evidence from larval, megalopal and early juvenile morphology Naturalis
McLaughlin, Patsy A.; Lemaitre, Rafael; Tudge, Christopher C..
In this second of a two-part series, carcinization in the Anomura has been reviewed from early juvenile, megalopal, and larval perspectives. Data from megalopal and early juvenile development in ten genera of the Lithodidae have provided unequivocal evidence that earlier hypotheses regarding evolution of the king crab pleon were erroneous. A pattern of sundering, and decalcification has been traced from the megalopal stage through several early crabs stages in species of Lithodes and Paralomis, with supplemental evidence from species in eight other genera. Of major significance has been the attention directed to the marginal plates of the second pleomere, which when separated in lithodids are not homologous with the adult so-called “marginal plates” of the...

Comparative study of shell choice by the southern endemic hermit crab Loxopagurus loxochelis from Brazil and Argentina RChHN
BIAGI,RENATA; MEIRELES,ANDREA L; SCELZO,MARCELO A; MANTELATTO,FERNANDO L.
This study aimed to determine the shell choice pattern of the southern Atlantic endemic hermit crab Loxopagurus loxochelis from two different biogeographic provinces in Brazil and Argentina. Size and shell species preferences were determined for the two most occupied shell types (i.e., Olivancillaria urceus and Buccinanops gradatum) in Caraguatatuba region (Brazil) and in Mar del Plata (Argentina). Shell occupation was analyzed considering the biometric characteristics of shells, the occurrence of shell types, and the preference of the hermit crabs for the most frequently occupied shell species. Samples were taken using otter trawl in the infralittoral area of both regions and the animals captured were measured and weighed. Shells were identified, weighed,...

Comparison of different methodologies for DNA extraction from Aegla longirostri BABT
Bitencourt,João Vitor Trindade; Roratto,Paula Angélica; Bartholomei-Santos,Marlise Ladvocat; Santos,Sandro.
The aim of this study was to compare some DNA extraction methodologies for Aegla longirostri. The protocols were based on the traditional phenol-chloroform DNA extraction methodology and using a commercial kit for DNA extraction. They differed in tissues used, the addition - or not - of beta-mercaptoethanol to the lysis buffer, times and methods for the animal's conservation (frozen, in ethanol or fresh). Individuals stored at -20°C for a long time supplied lower molecular weight DNA than those stored for a short time. The best yield for the specimens preserved in ethanol was obtained for 15 days storage in 95% ethanol. The kit resulted in a low quantity of high molecular weight DNA. The best protocol for DNA extraction from Aeglidae, and probably for...

First record of the genus Eumunida Smith, 1883 (Crustacea, Decapoda, Eumunididae) from the southwestern Atlantic, with the description of a new species Pap. Avulsos de Zool. (São Paulo)
Tavares,Marcos; Lima,Daniel.
Abstract Eumunida pictaSmith, 1883, was considered for over a century an amphi-Atlantic species and the only representative of the genus in the Atlantic Ocean, until being split into three species: E. picta sensu stricto (from the northwestern Atlantic), E. bellade Saint Laurent & Macpherson, 1990 and E. squamiferade Saint Laurent & Macpherson, 1990 (from the northeastern and southeastern Atlantic, respectively). Eumunida is now expanded to include a new species, E. notialis, from off the Brazilian coast. Hence, this is the first record of Eumunida and Eumunididae from the southwestern Atlantic. The new species differs from all its Atlantic counterparts in having (1) four hepatic spines; (2) two carapace inframarginal spines; (3) the distal end of...

Growth of the hermit crab Clibanarius vittatus (Bosc, 1802) (Crustacea, Anomura, Diogenidae) at São Vicente, São Paulo, Brazil BABT
Sant’Anna,Bruno Sampaio; Christofoletti,Ronaldo Adriano; Zangrande,Cilene Mariane; Reigada,Alvaro Luis Diogo.
The present study analyzed the growth of males and females of the hermit crab Clibanarius vittatus (Bosc, 1802), at São Vicente, São Paulo, Brazil. Monthly collections were made from May/2001 through April/2003, at the Pescadores Beach in São Vicente. The 2,501 crabs caught were identified and sexed and the carapace shield length (CSL) was measured. For the seasonal growth study, the population was divided into 5mm size classes (CSL) and analyzed by the Bertalanffy method, with the aid of the program Fisat II. The mean sizes of the 703 males and 1,798 females were 8.94±1.80 and 6.61±1.13 mm, respectively. A seasonal growth pattern was observed, with males reaching an asymptotic size (14.92 mm) larger than that of females (13.85 mm). Males began the growth...

Phylogeny of the Anomura (Decapoda, Crustacea): Spermatozoa and spermatophore morphological evidence Naturalis
Tudge, Christopher C..
A phylogenetic analysis of selected anomuran, thalassinidean, and other decapod crustacean taxa, based on spermatozoal ultrastructural characters and spermatophore morphological characters, was performed and the following relationships of the taxa are elucidated from the trees produced. The Anomura are not a monophyletic assemblage, with the lomoid Lomis being exclusive of the remainder of the anomuran taxa, and the thalassinid Thalassina included in the anomuran clade. The synapomorphy joining the majority of the conventional anomuran taxa ( Lomis excluded) is the cytoplasmic origin of the microtubular arms. When the palinurid and thalassinoid representatives are separately designated as outgroups, the Astacidea and Brachyura jointly formed a sister group...

Jagt, J.W.M.; Fraaije, R.H.B.; Bakel, B.W.M. van.
Strata of latest Cretaceous (late Maastrichtian) and earliest Paleogene (early Paleocene) age in the (extended) type area of the Maastrichtian Stage are comparatively rich in decapod crustaceans. Particularly common are chelae of the callianassoid Mesostylus faujasi (Desmarest, 1822), followed by carapaces of various species of necrocarcinid and raninid, plus the ?longusorbiid Binkhorstia ubaghsii (van Binkhorst, 1857) and chelae of paguroids; other taxa are much rarer. Recently collected material, all stratigraphically well constrained, has enabled us to reinterpret, and reassign, a number of species. Specimens contained in old museum collections have proved indispensable in that respect. Undescribed taxa have also come to light; here a new dromioid,...

Species of the genus Munidopsis (Crustacea, Decapoda, Galatheidae) from the deep Atlantic Ocean, including cold-seep and hydrothermal vent areas ArchiMer
Macpherson, E; Segonzac, Michel.
Twenty-two species of the genus Munidopsis from the Atlantic Ocean are studied. Five new species are described (M. anemia, M. exuta, M. hirtella, M. laurentae and M. truculenta), and diagnoses and illustrations of some relatively rare species (M. acuminata, M. bairdii, M. livida, M. parfaiti and M. thieli) are provided. None of the species discussed here is restricted to a particular habitat, including species collected from hydrothermal vent (M. acutispina, M. exuta) and cold seep areas (M. acutispina, M. geyeri, M. hirtella, M. livida, M. marionis). The new records of some species greatly extend the previously known distribution range of the species (i.e., M. abyssicola, M. aries, M. bairdii, M. geyeri, M. livida, M. parfaiti, M. thieli). Finally, some...

The influence of shell species and size on the shell selection pattern of Paguristes tortugae (Decapoda, Diogenidae) from Anchieta Island (Ubatuba, Brazil) Iheringia, Sér. Zool.
Dominciano,Laura C. C.; Mantelatto,Fernando L. M..
Shell selection by the hermit crab Paguristes tortugae Schmitt, 1933 from Anchieta Island (Brazil) was analyzed using the six most frequently occupied shell species in the field and taking into account the sexual condition of the individuals, the shell size and the shell species. The experiments were conducted under laboratory conditions and the shell species preference was estimated on the basis of the frequency that each species was chosen by the individuals. The preferred shell species and size were determined by regression analysis. The highest correlation coefficients were obtained for the relations between the hermit dimensions and shell dry weight. The ovigerous females preferred shells with larger internal volume: Leucozonia nassa (Gmelin, 1791)...
