Crustacea Decapoda: les Cyclodorippidae et Cymonomidae de l'Indo-Ouest-Pacifique à l'exclusion du genre Cymonomus

This is part of a séries of papers (TAVARES, 1991a, 1991b, 1992a, 1992b, 1992c) reviewing the Cyclodorippidae Ortmann, 1892, and Cymonomidae Bouvier, 1897, of the world. It contains a review of ail the Cyclodorippidae from the Indo-West Pacific as well as one genus of Cymonomidae. This is a systematic approach preceding a more detailed study of the Cyclodorippoidea morphology and of the phylogenetic relationships within the superfamily. The présent work was based upon large collections from the Indo-West Pacific (Madagascar, Japan, Vietnam, Philippines, Indonesia, Australia, Chesterfield Islands, New Caledonia, Loyalty Islands, and Wallis and Futuna Islands) carried out by the following French expéditions : MUSORSTOM 1-7, BIOCAL, CHALCAL 2, CORAIL 2, KARUBAR, LAGON, and SMIB 6. Also included is the material collected by the "Siboga" Expédition, 1899, CRUSTACEA DECAPODA : CYCLODORIPPIDAE ET CYMONOMIDAE 255 "Albatross", 1908, the material collected by the Russian océanographie ships "Orlik" in 1960 on the coast of Vietnam and "Vytiatz" on the west coast of Australia, two samples made by Raoul SERÈNE in Indonesia in during the RUMPHIUS I expédition in 1973 and RUMPHIUS IV in 1975, as well as collections made by the Australian ship "Soela" in 1984 on the north coast of Australia, and others made during the expédition CiDARis I under the auspices of the James Cook University on the Great Barrier Reef. Additional material from the collections of The Natural History Muséum (British Muséum), London ; Muséum of Comparative Zoology, Massachusetts ; Zoological Muséum of Moscow University ; National Science Muséum, Tokyo ; Northern Territory Muséum of Arts and Science, Darwin ; Queensland Muséum, Brisbane ; South African Muséum, Cape Town ; National Muséum of Natural History, Smithsonian Institution, Washington and Zoôlogisch Muséum, Amsterdam was also examined. Because of insufficient original descriptions, the re-examination of ail type spécimens [except for Tymolus truncatus (Ihle, 1916) which is apparently lost and Genkaia gordonae Miyaké and Takeda, 1970] and most of the spécimens cited in the literature, was required to properly establish the correspondence between species and the names introduced in the literature. Until now, seven gênera (Tymolus, Corycodus, Xeinostoma, Genkaia, Krangalangia, Ketamia, and Cymonomus) and 23 species of Cyclodorippidae and Cymonomidae were known from the Indo-west Pacific. They are as foUows : Cyclodorippidae : Tymolus japonicus Stimpson, 1858, T. uncifer (Ortmann, 1892), T. dromioides (Ortmann, 1892), T. similis (Grant, 1905), T. truncatus (Ihle, 1916), T. brucei Tavares, 1991, Corycodus disjunctipes (Stebbing, 1910), Xeinostoma eucheir Stebbing, 1920, Krangalangia rostrata (Ihle, 1916), K. spinosa (Zarenkov, 1970), Ketamia depressa (Ihle, 1916), Genkaia gordonae Miyaké and Takeda, 1970. Cymonomidae : Cymonomus valdiviae Lankaster, 1903, C. andamanicus Alcock, 1905, C. indicus Ihle, 1916, C. trifurcus Stebbing, 1920, C. japonicus Balss, 1922, C. curvirostris Sakai, 1965, C. aequilonius Dell, 1971, C. bathamae Dell, 1971, C. delli Griffin and Brown, 1976, C. umitake Takeda, 1981, C. hakuhoae Takeda and Moosa, 1990. From this study : — Two new gênera {Phyllotymolinum and Elassopodus) and 11 new species of Cyclodorippoidea are herein described : Cyclodorippidae : Corycodus merweae, C. decorus, Xeinostoma richeri, X. sakaii, Krangalangia orstom, Ketamia handokoi, K. limatula, K. proxima, Genkaia keijii, Phyllotymolinum crosnieri. Cymonomidae : Elassopodus stellatus. — Two species are resurrected : Corycodus bouvieri Ihle, 1916, from the synonymy of C. disjunctipes (Stebbing, 1910) and Krangalangia spinosa (Zarenkov, 1970) from the synonymy of A", rostrata (Ihle, 1916). — Four lectotypes are designated hère for the following species : Corycodus disjunctipes, Xeinostoma eucheir, Krangalangia rostrata, and Ketamia depressa. Presently, a total of 9 gênera (7 Cyclodorippidae and 2 Cymonomidae) and 34 species (22 Cyclodorippidae and 12 Cymonomidae) are known from the Indo-West Pacific. Ail thèse species are studied hère except those belonging to the genus Cymonomus which will be treated in a future publication. Keys for families, gênera and species are provided as well as illusfrations for ail species.
