AN ANNOTATED CHECKLIST OF EXTANT BRACHYURAN CRABS OF THE WORLD Peter K. L.

F. Davie Queensland Museum, PO Box 3300, South Brisbane, Queensland, Australia Email: [email protected] ABSTRACT. – An annotated checklist of the extant brachyuran crabs of the world is presented for the first time. 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. KEY WORDS. – Annotated checklist, crabs of the world, Brachyura, systematics, nomenclature.

Progress in our understanding of phylogenetic relationships within the Crustacea is linked to continuing discoveries of new taxa, to advances in theory and to improvements in methodology. Six themes are discussed that serve to illustrate some of the major on-going controversies and unresolved problems in the field as well as to illustrate changes that have taken place since the time of Linnaeus. These themes are: 1. the treatment of parasitic Crustacea, 2. the affinities of the Remipedia, 3. the validity of the Entomostraca, 4. exopodites and epipodites, 5. using larval characters in estimating phylogenetic rela- tionships, and 6. fossils and the crustacean stem-lineage. It is concluded that the development of the stem lineage concept for the Crustacea has been dominated by consideration of taxa known only from larval or immature stages.

E-mails: (AFT) [email protected]; (FLM) [email protected] Abstract The present study provided information extending the known geographical distribution of three species of majoid crabs, the epialtids Acanthonyx dissimulatus Coelho, 1993, Epialtus bituberculatus H. 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).

Rizalthus, new genus, with just one species, R. anconis, new species, can be distinguished from allied genera by characters of the carapace, epistome, chelipeds, male abdomen and male fi rst gonopod. Visayax, new genus, contains two new species, V. osteodictyon and V. estampadori, and can be distinguished from similar genera using a combination of features of the carapace, epistome, thoracic sternum, male abdomen, pereiopods and male fi rst gonopod. A new species of Hepatoporus Serène, H. pumex, is also described. It is distinguished from congeners by the unique morphology of its front, carapace sculpturing, form of the subhepatic cavity and structure of the male fi rst gonopod.

Ctenocheles sp. (Axiidea: Ctenochelidae), Anatolikos japonicus (Ortmann) (Brachyura: Cancridae), and two species of Charybdis (Brachyura: Portunidae) are included. Charybdis (Charybdis) kinugawai Karasawa, a new portunid is described. Key words: Decapoda, Axiidea, Brachyura, Ananai Formation, Pliocene–Pleistocene, Japan Introduction Systematics (By Karasawa) The Pliocene–Pleistocene Tonohama Group is distributed in the western part of the Muroto Peninsula, Kochi Prefecture, Shikoku. This Infraorder Axiidea de Saint Laurent, 1979 group consists of the Nobori, Ananai, and Ropponmatsu Formations in Superfamily Callianassoidea Dana, 1852 ascending order (Katto and Masuda, 1993; Iwai et al., 2006). Matsubara Family Ctenochelidae Manning and Felder, 1991 (2004) reviewed the geologic age of the Tonohama Group based Subfamily Ctenochelinae Manning and Felder, 1991 upon the previously known microfossils. He showed that the Nobori Genus Ctenocheles Kishinouye, 1926 Formation was assigned to the late early Pliocene–early late Pliocene (4.20–3.21 or 3.12 Ma; Berggren et al., 1995) and that the geological Ctenocheles sp. age of the Ananai Formation was the late Pliocene (2.78 or 2.73–1.97 (Fig. 1.1, 1.2) Ma) (=late Pliocene–early Pleistocene based upon Cohen and Gibbard, Material examined: Incomplete propodi of 1 st pereiopod, 2011).
