| Specimens of species closely related to the rare deep-sea lobster Thaumastocheles japonicus Calman, 1913 were obtained from recent deep-sea expeditions in the West Pacific. Close examination of these specimens, as well as molecular analysis, showed that they represent two species new to science, with many morphological and significant genetic differences (barcoding gene COI sequence divergences 11.5-14.8%) between each other as well as T japonicus. Re-examination of the specimens previously assigned to T japonicus revealed that true T japonicus has a more northern distribution, from Japan to the South China Sea and the Philippines. The two new species have more southern distributions with T. bipristis n. sp. restricted to the Philippines and Indonesia, and... |

| The cyclodorippoid crabs from the Philippines collected by the PANGLAO 2004-2005 and AURORA 2007 expeditions are reported. Five species of Cyclodorippidae are reported: Corycodus mina x sp. nov., Ketamia depressa (Ihle, 1916), Krangalangia spinosa (Zarenkov, 1970), Tymolus brucei Tavares, 1991, and Xeinostoma sakaii Tavares, 1993. Corycodus minax is the second species of the genus to be recorded from the Philippines and is most similar to C. merweae Tavares, 1993, from South Africa. Krangalangia spinosa is reported for the first time from the Philippines. Sexual dimorphism in the length of the walking legs (pereopods 2 and 3) is reported for Tymolus brucei and may be a general feature of cyclodorippoids. One new species of Cymonomidae, Cymonomus liui sp.... |

| The deep-sea squat lobster, Munidopsis serricornis (Loven, 1852), originally described from the north-eastern Atlantic, has long been considered near cosmopolitan with numerous reports also from the western Pacific and northern Indian Ocean. These Indo-West Pacific records are reviewed along with new material from seamounts throughout the region. Munidopsis serricornis sensu stricto is restricted to the Atlantic Ocean. Six new species are described from the Indo-West Pacific: M alcocki sp. nov. from the central to western Indian Ocean; M atlantis sp. nov., from the Southwest Indian Ridge; M macphersoni sp. nov. from the Austral Islands, French Polynesia; M spiridonovi sp. nov. from the western Indian Ocean; M nias sp. nov. from southern Indonesia and the... |

| Macquarie Ridge is one of the southernmost seamount ridges, spanning 1600 kilometres from the southern tip of New Zealand to the Australia-Pacific-Antarctic triple junction halfway to Antarctica. Squat lobsters, superfamilies Chirostyloidea and Galatheoidea, are highly diverse at low and mid-latitudes, declining rapidly towards the poles; only 15 of the more than 1000 species have been recorded south of 50 degrees S. Prior to the present study, one species of squat lobster (Munidopsis pyrochela, Munidopsidae) was known from the Macquarie Ridge, but recent research voyages in 2003 and 2008 collected a further five species from both superfamilies and three families. Uroptychus tracey (Chirostylidae) is new to science. Uroptychus insignis (Henderson, 1885) is... |
