The status of Podotremata is one of the most controversial issues in brachyuran systematics. The podotreme crabs, best recognised by the possession of gonopores on the coxae of the pereopods, have variously been regarded as mono-, para- or polyphyletic, or even as non-brachyuran. For the first time, the phylogenetic positions of the podotreme crabs were studied by cladistic analysis of small subunit nuclear ribosomal RNA sequences. Eight of 10 podotreme families were represented along with representatives of 17 eubr- achyuran families. Under both maximum parsimony and Bayesian Inference, Podotremata was found to be significantly paraphyletic, comprising three major clades: Dromiacea, Raninoida, and Cyclodorippoida. The most ‘basal’ is Dromiacea, followed by Raninoida and Cylodorippoida. Notably, Cyclodorippoida was identified as the sister group of the Eubrachyura.

WILLIAMS Deceased in 1999 National Marine Fisheries Service Systematics Laboratory, National Museum of Natural History, Smithsonian Institution, Washington DC 20560 (USA) Lara L. COOPER Biodiversity Science Branch, Fisheries and Oceans Canada Ottawa, Ontario, KIA OE6 (Canada) Castro P., Williams A. B. & Cooper L. L. 2003. — Revision of the family Latreilliidae Stimpson, 1858 (Crustacea, Decapoda, Brachyura). Zoosystema 25 (4): 601-634. ABSTRACT A study of specimens from around the world and the re-examination of addi- tional material used by Williams for his revision of Latreillia Roux, 1830 have lead to a revision of the family Latreilliidae Stimpson, 1858 (Crustacea, Decapoda, Brachyura). The family now consists of two genera: Latreillia, with five species (L. elegans Roux, 1830, L. metanesa Williams, 1982, L. pen- nifera Alcock, 1900, L. valida de Haan, 1839, and L. williamsi Melo, 1990), and Eplumula Williams, 1982, with two species (E. australiensis (Henderson, 1888) and E. phalangium (de Haan, 1839)). Latreillia manningi Williams, 1982, which was described as a western Atlantic species distinct from the Mediterranean and eastern Atlantic populations of L. elegans, is now regarded as a very close geographical variant of L. elegans because the differences between the two populations are insignificant and overlapping. The revision KEY WORDS has resulted in an updated and more detailed definition of the Latreilliidae Crustacea, with the addition of characters such as the type of abdominal holding system Decapoda, Brachyura, and the morphology of the coxae of the last pair of pereopods (P5) of males.

A worldwide taxonomic and distributional synthesis of the deep-water hermit crab genus Oncopagurus Lemaitre, 1996 is presented. This genus, originally defi ned for 10 species is set apart from other Parapaguridae as well as other Paguroidea, by one synapomorphy: the presence of an upwardly curved epistomial spine. This study is based on a large amount of specimens deposited in major museums and collected during deep-sea sampling across the world oceans since the late 1800s, with the bulk of material coming from French campaigns in the Indo-Pacifi c, central and south Pacifi c during the last 40 years. A total of 24 species are recognised in this investigation, nine of which are new and fully described and illustrated. All previously known species are diagnosed or re-described, including fi gures assembled from recent published accounts or newly illustrated, of the most important morphological features useful for identifi cations. Information for each species includes a synonymy (full or abbreviated if a synonymy has recently been published), material examined (type and non-types), variations when signifi cant, colouration when available, habitat or type of housing used, distribution, and remarks on taxonomy and morphological affi nities. Rare colour photographs are included for fi ve species.

  • Hermit Crabs from the South China Sea (Crustacea: Decapoda: Anomura: Diogenidae, Paguridae, Parapaguridae)
    THE RAFFLES BULLETIN OF ZOOLOGY 2000 Supplement No. 8: 377-404 © National University of Singapore HERMIT CRABS FROM THE SOUTH CHINA SEA (CRUSTACEA: DECAPODA: ANOMURA: DIOGENIDAE, PAGURIDAE, PARAPAGURIDAE) Dwi Listyo Rahayu Rand D Center for Oceanology, Indonesian Institute of Sciences (LIP/), Jt. Pasir Putih I, Ancol Timur, PO Box 4801 JKTF, Jakarta 11048, Indonesia ABSTRACT. - One hundred and two species of hermit crabs are recorded from the South China Sea. Information presented is from published references to the species. Most of the species are widely distributed in the Indo-West Pacific. INTRODUCTION Studies on hermit crabs of the South China Sea were done mostly according to country border and not to geographical border, such as hermit crab of Singapore and Malaysia (Nobili, 1900; 1903a, c; Lanchester, 1902; Rahayu, 1996), Vietnam (Fize & Serene, 1955; Forest, 1956c; 1958), Philippines (Estampador, 1937, 1959), Taiwan (Yu, 1987; Yu & Foo, 1990) and China (Wang, 1994). Some hermit crabs from this region are mentioned in the revision of one or more taxonomical groups, such as revision of the family Parapaguridae (de Saint Laurent, 1972; Lemaitre, 1996, 1997), genus Aniculus (Forest, 1984), genus Pagurixus (McLaughlin & Haig, 1984), genus Pylopaguropsis (McLaughlin & Haig, 1989), genus Pylopagurus and Tomopagurus (McLaughlin & Gunn, 1992) and genus Trizopagurus (Forest, 1995). One hundred and two species belonging to family Diogenidae, Paguridae and Parapaguridae are recorded from the South China Sea. The family Diogenidae is represented by eight genera (Aniculus, Calcinus, Ciliopagurus, Clibanarius, Dardanus, Diogenes, Paguristes and Strigopagurus), the family Paguridae is represented by eight genera (Australeremus, Ceratopagurus, Nematopagurus, Paguritta, Pagurixus, Pagurus, Pylopaguropsis and Spiropagurus) and the family Parapaguridae is represented by four genera (Bivalvopagurus, Oncopagurus, Paragiopagurus, and Sympagurus).
