Four New Species of Galatheidean Crustacea from New Zealand Waters

Abstract A collection of Crustacea Galatheidea made by the Japanese Fisheries Research Vessel “Kaiyo Maru” off the east coast of the South Island, New Zealand, contains four new species described here: Gastroptychus novaezelandiae sp. nov., Uroptychus tomentosus sp. nov., Munida chathamensis sp. nov., and Munidopsis kaiyoae sp. nov.

TWO NEW SPECIES OF CHIROSTYLIDS (DECAPODA: ANOMURA: CHIROSTYLIDAE) FROM TASMANIA

Two new anomuran crustaceans from Tasmania are described and illustrated. Gastroptychus rogeri, new species, is similar to G. hendersoni (Alcock and Anderson, 1899) in the carapace spination but may be distinguished by having very spinose abdominal segments. Uroptychus raymondi, new species, is characterized by the combination of a strong midlateral spine on the carapace, a short, relatively broad antenna! scale, and a short antenna! flagellum, which differentiates the species from U. valdiviae Balss, 1913.

A checklist of Crustacea Decapoda collected from Conic Island Cave and adjacent areas of Hong Kong

During October 2002, the benthic communities of Conic Island Cave and the adjacent sea area of Hong Kong were sampled by SCUBA divers. Twenty genera and 21 decapod species were identified with seven species being reported from Hong Kong for the first time.

TWO NEW SPECIES OF ANOMURAN CRUSTACEANS (DECAPODA: CHIROSTYLIDAE AND GALATHEIDAE) FROM THE ANDAMAN SEA

Two new species of anomuran crustaceans, Gastroptychus chacei (family Chirostylidae) and Munida sentai (family Galatheidae), are described from specimens taken in the Andaman Sea off southern Thailand. Three galatheids collected from the Andaman Sea off southern Thailand in 267283 m by the TV Nagasaki-maru were made available by Dr. Tetsushi Senta of Nagasaki University. They proved to represent two new species. Gastroptychus chacei, a chirostylid, is unique among the previously known members of the genus, in some respects indicating an affinity with Uroptychus. Munida sentai is one of the rare galatheids having few spines on the branchial margin of the carapace. The type material will be deposited in the National Museum of Natural History, Smithsonian Institution, Washington, D.C.

Revision of the genus sadayoshia (anomura, galatheidae), with description of four new species

A revision of the genus Sadayoshia Baba, 1969 (type species: S. miyakei Baba, 1969) is carried out based on more than 460 specimens from numerous localities in the Indo-Pacific, revealing the existence of seven species. Sadayoshia edwardsii (Miers, 1884) is redescribed using material collected near the type locality (SW Indian Ocean) and from numerous localities from the Indian and Pacific Oceans. The three previously described species (S. acroporae , S. balica , and S. miyakei ) proved to be valid species. Four additional species are described here as new to science: S. latisternata n. sp. from French Polynesia, Loyalty Islands and Mauritius Island; S. lipkei n. sp. from French Polynesia, Solomon Islands, Vanuatu, New Caledonia, Loyalty Islands and Chesterfield Islands; S. inermis n. sp. from Solomon Islands, Vanuatu and New Caledonia; and S. tenuirostris n. sp. from Japan, South China Sea, Palau Islands, Philippines, Indonesia, Solomon Islands, Vanuatu and New Caledonia.

Uroptychus minutus Benedict, 1902 and a closely related new species (Crustacea: Anomura: Chirostylidae) from the western Atlantic Ocean.

A new squat lobster, Uroptychus marissae, is described based upon two specimens taken associated with the antipatharian Tanacetipathes sp. from the northern Gulf of Mexico, at a depth of about 90 m. It closely resembles U. minutus Benedict, 1902, known only from the type material from off Trinidad. The original description is so brief that an opportunity is taken here to redescribe it to help discriminate between the two species.

Uroptychus nitidus (A. Milne-Edwards, 1880) and related species (Crustacea: Decapoda: Anomura: Chirostylidae) from the western Atlantic

Eight species of squat lobsters of the genus Uroptychus are reported from the western Atlantic based on the collections of the Museum of Comparative Zoology at Harvard, the Smithsonian Institution and Texas A&M University. Uroptychus nitidus (A. Milne-Edwards, 1880) is reviewed and redescribed, with a syntype taken at Blake Station 200 off Martinique designated as the lectotype. Uroptychus alphonsei n. sp. is named for U. nitidus variety C Chace, 1942, U. fenneri n. sp. for U. nitidus variety A Chace, 1942, and U. janiceae n. sp. for U. nitidus variety B Chace, 1942; U. lindae n. sp. is described on the basis of specimens collected by the Alaminos in the Caribbean Sea off northern Columbia; U. rafai n. sp. is described based on a sole specimen taken from the Straits of Florida; U. reedae n. sp. is described from among the syntypes of U. nitidus; and U. uncifer (A. Milne-Edwards, 1880) is redescribed to elaborate on its specific status, with the designation of lectotype from Blake Station 299 off the coast of Barbados. The number of species of Uroptychus from the western Atlantic now stands at 21. A key to these species is provided.

Uroptychus atlanticus , a new species of squat lobster (Crustacea: Decapoda: Anomura: Chirostylidae) from the western Atlantic Ocean

A new species of squat lobster, Uroptychus atlanticus, is described on the basis of a female specimen taken at a depth of 713-841 m in the southeastern Gulf of Mexico. The new species is readily distinguished from all known species of the genus from the western Atlantic by the very spinose carapace and pereopods, and a transverse row of spines on each of the abdominal tergites 1 and 2.

Uroptychus michaeli (Decapoda, Chirostylidae), a new species of deep-water squat lobster from north-western Australia and Taiwan

Uroptychus michaeli sp. nov. is described from northwestern Australia and Taiwan. The new species closely resembles U. nigricapillis , to which northwestern Australian and some Taiwanese records had been previously referred. Uroptychus michaeli sp. nov. is readily distinguished from U. nigricapillis by the deeply excavate cervical groove on the carapace (versus shallow, weakly indicated), more elongate pereopods 2-4 in which the pereopod 2 merus is longer than the postorbital carapace length (versus shorter), and the proportionally longer pereopod 2 carpus, which is as long as or longer than half postorbital carapace length (versus less than half) and approximately twice the length of the dactylus (versus 1.2× or less).
