  • 68 Guide to Crustacea
    68 Guide to Crustacea. The arrow indicates the course of the respiratory current, which, however, may sometimes be temporarily reversed, especially in burrowing species. The typical members of the family Portunidae (Swimming FIG. 46. Pseudocarcinus gigas, from Tasmania. The carapace of this specimen is just over a foot in width. [Above Wall-cases Nos. 5 and 6.] Crabs) may be recognised by the flattened, paddle-shaped, last pair of legs. Two British species of the genus Portunus are exhibited : the colours of P. depurator have been carefully copied from a living individual, and the specimen is mounted on a sample Decapoda—Brachyura. 69 of the shell-gravel on which it was actually caught. The large Neptunus pelagicus is the commonest edible Crab in many parts of the East. The Common Shore Crab, Carcinus maenas, is also referred to this family, although the paddle-shape of the last legs is not so marked as in the more typical Portunidae. Podophthalmus vigil (Fig. 47) is remarkable for the great length of the eye-stalks, which is quite unusual among the Cyclometopa, and gives this Crab a curious likeness to the genus Macrophthalmus among the Ocypodidae (see Table-case No. 16). The resemblance, however, is quite superficial, for in this case FIG. 47. Podophthalmus vigil (reduced). [Table-case No. 15.] it is the first of the two segments of the eye-stalk which is elongated, while in Macrophthalmus it is the second. The genus Platyonychus, of which a group of specimens is mounted in Wall-case No. 5, also belongs to this family.

Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

  • The Genus Phlyctenodes Milne Edwards, 1862 (Crustacea: Decapoda: Xanthidae) in the Eocene of Europe

Croce 1730, I - 30125, Venezia, Italia. 2 via Barbarigo 10, I – 30126, Lido di Venezia, Italia. 3 Associazione Amici del Museo Zannato, Piazza Marconi 15, I - 36075, Montecchio Maggiore (Vicenza), Italia. * [email protected] ABSTRACT A systematic review of the crab genus Phlyctenodes Milne Edwards, 1862 is carried out. Based on carapace features, this taxon is placed in the subfamily Actaeinae, family Xanthidae MacLeay, 1838. Species attributed to this genus are known from Eocene reef environments in Europe. Preservation of crustacean remains in this kind of environment is very rare, and it could explain scarcity of specimens of this genus. For the fi rst time, pictures of types of this genus described during the XIX century and the fi rst decades of the XX century are presented. A study of recently collected specimens from the Eocene of Veneto (Italy) allows to clarify relationships between Phlyctenodes krenneri Lörenthey, 1898 and P. dalpiazi Fabiani, 1911. Presence of P. tuberculosus Milne Edwards, 1862 among the new material is documented. The other known species of this genus, P. hantkeni Lörenthey, 1898 is placed in Pseudophlyctenodes new genus on the basis of differences in morphological features. Key words: Crustacea, Decapoda, Phlyctenodes, systematic review, Eocene, Italy. RESUMEN Se presenta una revisión sistemática del género de cangrejo Phlyctenodes Milne Edwards, 1862. Con base en las características del caparazón, este taxon es ubicado en la subfamilia Actaeinae, familia Xanthidae MacLeay, 1838.

  • Reduced Mobility Is Associated with Compensatory Feeding and Increased Diet Breadth of Marine Crabs
    MARINE ECOLOGY PROGRESS SERIES Published November 3 Mar Ecol Prog Ser Reduced mobility is associated with compensatory feeding and increased diet breadth of marine crabs John J. Stachowicz*,Mark Hay8* University of North Carolina at Chapel Hill, Institute of Marine Sciences. Morehead City, North Carolina 28557. USA ABSTRACT: Direct effects of predation have been widely recognized as important in affecting prey population dynamics and evolution. However, less attention has been devoted to the consequences of indirect effects of predators on prey behavior. For example, to avoid predation many animals restrict their activities to physical refugia and adopt low-mobility Mestyles, yet the consequences of these anti- predator behaviors for foraging and diet selection are relatively unknown. In this study we examine the relationships between mobility, feeding preferences, and compensatory feeding for 3 species of marine decapod crabs feeding on seaweeds in North Carolina, USA. Low mobility and high site fidellty of crabs were associated with a broad, non-selective diet and compensatory feeding. The majid Mithrax forceps exhibited the lowest mobility, highest site fidelity, and least selective diet of the 3 species, whereas another majid Libinia dubia was intermehate in both rnobllity and selectivity, and the xanthid Panopeus herbstii had the greatest mobility and narrowest diet. Of these 3 crabs, only M. forceps com- pensated for low food quality by increasing consumption rates in single food-species feeding assays. This may be because M. forceps is resistant to (or tolerant of) seaweed chemical defenses, while other crab species are not. The ability to consume, and presumably subsist on, a wide variety of potential foods including those defended from more mobile consumers may facilitate a low-mobllity lifestyle, allowing the crab to minimize movement and reduce exposure to predators.

SPATIO-TEMPORAL DISTRIBUTION OF ASSEMBLAGES OF BRACHYURAN CRABS AT LAAMU ATOLL, MALDIVES BY A. A. J. KUMAR AND S. G. WESLEY ABSTRACT A spatio-temporal study of the brachyuran assemblages at five marine habitats at Maavah Island, Laamu atoll, Maldives, was conducted for a period of two years from April 2001 to March 2003. Forty-seven species and a sub-species were collected from the study sites. An analysis of the species diversity of the study sites revealed that distributions of families and species were site-specific although some species have wider distributions than others and that there were seasonal variations at some of the sites. The highest species richness (S = 32) and the highest diversity index was shown by a site at north lagoon, which has complex and heterogeneous habitats. The south-east beach brachyuran community, which was low in species richness, exhibited the lowest evenness. An analysis of the constancy index of the different brachyuran communities revealed that the ratio of the species number and abundance of the constant species were considerably higher than the accessory and accidental species.
