ABSTRACT Tangle nets set in deep water on steep cliffs off the Philippine island of Balicasag have obtained numerous interesting species in recent years. A detailed description of the fishing gear and its use, as observed in Balicasag Island, central Philippines, is provided. Tangle net fishing has been shown to efficiently collect specimens from areas that cannot be easily sampled using conventional gear such as trawls and dredges. Tangle nets, therefore, can be used to complement other methods during marine biodiversity surveys.

    ABSTRACT: Several marine expeditions have been conducted in the Philippine Archipelago since the early part of the 19 th century, and have documented the rich diversity of crustaceans collected from these islands. In addition, the recently concluded PANGLAO 2004 and 2005 expeditions to the central Philippines, and the AURORA 2007 expedition to the northeastern Philippines have yielded a diverse array of shallow and deep-water marine animals, particularly brachyuran crustaceans. The family Xanthidae is among the best represented of these brachyurans. As part of a continuing effort to fully document the Brachyura of the Philippines, we report here the occurrence of 25 species belonging to the subfamily Euxanthinae (Brachyura: Xanthidae), with two recently described new genera, fi ve recently described new species and six new country records.

    ABSTRACT: Two undescribed species of Scopimera are herein described. Scopimera sheni sp. nov. from Qingdao, represents the fourth species of the genus to be recognized from North China. Scopimera philippinensis sp. nov. is the first record of the genus from the Philippines. Morphologically both new species belong to the "normal form" Scopimera (sensu Kemp 1919). Amongst other characters, each can be distinguished by its diagnostic male first gonopod. Mitochondrial cytochrome ox-idase I (COI) gene sequences showed two distinct clades. An East Asia group (Chinese coasts, Japan, Korea and Taiwan) consisting of S. globosa De Haan, 1835, S. ryukyuensis Wong, Chan et Shih, 2010, S. sheni sp. nov., S. longidactyla Shen, 1932 and S. curtelsona (= S. cutelsoma) Shen, 1936; and a Southeast Asia group consisting of the closely related S. phil-ippinensis sp. nov. and S. intermedia Balss, 1934. A dichotomous key is provided for all "normal forms" of Scopimera species.

    ABSTRACT: On the basis of fresh collections from various parts of the western Pacifi c, three species of majoid crabs previously considered as rare are redescribed and fi gured: Oxypleurodon bidens (Sakai, 1969), O. auritum (Rathbun, 1916) and O. coralliophilum (Takeda, 1980). Four new species are described: O. boholense from the Philippines, O. barazeri and O. parallelum from the Solomon Islands, and O. alaini from New Caledonia. A new genus and new species, Stegopleurodon planirostrum, is described from New Caledonia and Vanuatu. The two species currently assigned to the allied American genus Sphenocarcinus A. Milne-Edwards, 1875, are re-examined, and a new genus, Rhinocarcinus, is established for the Pacifi c species Sphenocarcinus agassizi Rathbun, 1893.
