These descriptions were analysed and zoeal char- acters compared, in order to assess diagnostic characters for their identification. An identification key is provided for family level and identification keys to species level are provided for most families. These keys were constructed using external morphological characters whenever possible, to decrease the need for dissection and make identifi- cation as easy as possible. Only the first zoeal stage was considered, as many descriptions only consider this stage. Keywords: Crustacea; Brachyura; larvae; morphology; key; first stage zoeas Introduction within each family.

  • The Biology of Terebra Gouldi Deshayes, 1859, and a Discussion Oflife History Similarities Among Other Terebrids of Similar Proboscis Type!
    Pacific Science (1975), Vol. 29, No.3, p. 227-241 Printed in Great Britain The Biology of Terebra gouldi Deshayes, 1859, and a Discussion ofLife History Similarities among Other Terebrids of Similar Proboscis Type! BRUCE A. MILLER2 ABSTRACT: Although gastropods of the family Terebridae are common in sub­ tidal sand communities throughout the tropics, Terebra gouldi, a species endemic to the Hawaiian Islands, is the first terebrid for which a complete life history is known. Unlike most toxoglossan gastropods, which immobilize their prey through invenomation, T. gouldi possesses no poison apparatus and captures its prey with a long muscular proboscis. It is a primary carnivore, preying exclusively on the enteropneust Ptychodera flava, a nonselective deposit feeder. The snail lies com­ pletely buried in the sand during the day, but emerges to search for prey after dark. Prey are initially detected by distance chemoreception, but contact of the anterior foot with the prey is necessary for proboscis eversion and feeding. The sexes in T. gouldi are separate, and copulation takes place under the sand. Six to eight spherical eggs are deposited in a stalked capsule, and large numbers of capsules are attached in a cluster to coral or pebbles. There is no planktonic larval stage. Juveniles hatch through a perforation in the capsule from 30-40 days after development begins and immediately burrow into the sand. Growth is relatively slow. Young individuals may grow more than 1 cm per year, but growth rates slow considerably with age. Adults grow to a maximum size of 8 cm and appear to live 7-10 years.

Milne Edwards, 1834, and E. brasiliensis Dana, 1852. Specimens of both genera from different carcinological collections were studied by comparing morphological characters. We provide new data that extends the geographical distributions of E. bituberculatus to the coast of the states of Paraná and Santa Catarina (Brazil), and offer new records from Belize and Costa Rica. Epialtus brasiliensis is recorded for the first time in the state of Rio Grande do Sul (Brazil), and A. dissimulatus is reported from Quintana Roo, Mexico. The distribution of A. dissimulatus, previously known as endemic to Brazil, has a gap between the states of Espírito Santo and Rio de Janeiro. However, this restricted southern distribution is herein amplified by the Mexican specimens. Key words: Geographic distribution, majoid, new records, spider crabs. Introduction (Melo, 1996).

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.

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.

  • New Records of Xanthid Crabs Atergatis Roseus (Rüppell, 1830) (Crustacea: Decapoda: Brachyura) from Iraqi Coast, South of Basrah City, Iraq
    Arthropods, 2017, 6(2): 54-58 Article New records of xanthid crabs Atergatis roseus (Rüppell, 1830) (Crustacea: Decapoda: Brachyura) from Iraqi coast, south of Basrah city, Iraq Khaled Khassaf Al-Khafaji, Aqeel Abdulsahib Al-Waeli, Tariq H. Al-Maliky Marine Biology Dep. Marine Science Centre, University of Basrah, Iraq E-mail: [email protected] Received 5 March 2017; Accepted 5 April 2017; Published online 1 June 2017 Abstracts Specimens of the The Brachyuran crab Atergatis roseus (Rüppell, 1830), were collected for first times from Iraqi coast, south Al-Faw, Basrah city, Iraq, in coast of northwest of Arabian Gulf. Morphological features and distribution pattern of this species are highlighted and a figure is provided. The material was mostly collected from the shallow subtidal and intertidal areas using trawl net and hand. Keywords xanthid crab; Atergatis roseus; Brachyura; Iraqi coast.

In comparison to other crustacean groups, brachyuran crabs have been well studied in the Arabian Gulf (=Persian Gulf) (Stephensen, 1946; Apel, 2001; Titgen, 1982; Naderloo and Sari, 2007; Naderloo and Türkay, 2012).
