| A new species of gall crab is described from the free-living stony coral Trachyphyllia geoffroyi. Specimens were collected during field work in Lembeh Strait (Indonesia) and of Kudat (Malaysian Borneo). This new species, here named Lithoscaptus semperi sp. n., is the ninth species assigned to the genus. It can be separated from its congeners by not having the internal orbital angle extending beyond the external orbital angle, and by the stout female P2 merus with prominent distomesial projection. In addition, the carapace surface appears smooth, despite having small tubercles on the anterior half, and is without noticeable spines, other than those on the frontal margin. The distinctive carapace pattern in life is a diagnostic character in male specimens. |

| A new species of cryptochirid crab, Fizesereneia panda van der Meij, is described and illustrated based on specimens collected from the scleractinian corals Lobophyllia cf. hemprichii and L. cf. corymbosa from the Farasan Banks, Farasan Islands, and the reefs off Thuwal in the Saudi Arabian Red Sea, and from Symphyllia recta from reefs in the Gulf of Oman. This is the second cryptochirid species with the Red Sea as type locality. It can be separated from its congeners by the subrectangular carapace, raised midline and the complete division of the carapace depressions, and reddish black colour pattern of these concavities in live specimens. This new species is the seventh assigned to Fizesereneia. A DNA barcode for the new species has been deposited in... |

| The Raja Ampat expedition in 2007 was organized by the National Museum of Natural History Naturalis in Leiden in cooperation with the Research Centre for Oceanography (RCO-LIPI, Jakarta) as part of Ekspedisi Widya Nusantara (E-Win expedition) of the Indonesian Institute of Sciences (LIPI). The research team consisted of scientists from Indonesia, the Netherlands, Palau and the United States. The Raja Ampat islands are located northwest of Bird’s Head' peninsula in Papua, Indonesia. This area has recently gained much media attention due to its high marine biodiversity and the recent discovery of several new species of corals and fish. The expedition was based at Kri Eco Resort of Papua Diving, on Kri Island. The expedition aimed to study cryptic biota,... |

| Coral-associated invertebrates dominate the biodiversity of coral reefs. Some of the associations involving symbiotic invertebrates remain unknown or little studied. This holds true even for relatively wellstudied coral reefs, like those in the Caribbean Sea. Coral gall crabs (Cryptochiridae), obligate symbionts of stony corals, form a much-overlooked component of coral reef communities. Most recent studies on the Atlantic members of Cryptochiridae have been conducted off Brazil and little recent data have become available from the Caribbean region. During fieldwork off Curaçao (southern Caribbean Sea), eight new host coral species, belonging to four coral families, were recorded for three cryptochirid species. Kroppcarcinus siderastreicola Badaro, Neves,... |

| The enigmatic gall crab family Cryptochiridae has been proposed to be phylogenetically derived from within the Grapsidae (subsection Thoracotremata), based on the analysis of 16S mtDNA of one cryptochirid, Hapalocarcinus marsupialis, among a wide array of thoracotremes, including 12 species of the family Grapsidae. Here,wetest the monophyly and phylogenetic position of Cryptochiridae using the same gene, but with an extended representation of cryptochirids spanning nine species in eight of 21 genera, in addition to further thoracotreme representatives. The results show that gall crabs form a highly supported monophyletic clade within the Thoracotremata, which evolved independently of grapsid crabs. Therefore, the Cryptochiridae should not be considered as... |

| During a week of fieldwork along the coast of Normandy, France, the author found a tropical carpet shell on the beach of Granville. Field guides could not properly identify the shell and therefore it was compared with the collections of the National Museum of Natural History in Leiden and the Zoological Museum of Amsterdam. This comparison resulted in four possible identifications - Ruditapes variegatus, Venerupis aurea, Ruditapes philippinarum and Ruditapes semidecussatus. However, the specific shell colour pattern does not fully correspond with the pattern of these four species, making identification of the shell difficult. The most likely identification seems to be Ruditapes semidecussatus. In France carpet shells are cultured for consumption. The... |

| Part of the genus Lioconcha Mörch, 1853 is reviewed. Species strongly resembling Lioconcha castrensis (Linnaeus, 1758) are discussed and two new species are described: Lioconcha arabaya n. sp. from the Northwest Indian Ocean and Lioconcha rumphii n. sp. from Thailand and Sumatra. These three species, together with Lioconcha macaulayi Lamprell & Healy, 2002, share many morphological similarities and we suspect them to be closely related. They are referred to as the Lioconcha castrensis species group. Furthermore, lectotypes of Venus castrensis Linnaeus, 1758, and Venus fulminea Röding, 1798, are designated. The latter is considered a junior synonym of V. castrensis. |

| Botanical and zoological collections may serve as archives for historical ecological research on the effects of global change and human impact on coral reef biota. Museum collections may harbour old specimens of reef-dwelling species that have become locally extinct. Such collections also help to determine whether early records of invasive species can be obtained from times when they were not yet recognized as such. A case study (2006) involving Saba Bank, Caribbean Netherlands (former Netherlands Antilles), suggests that the coral reef fauna here may have become impoverished when compared with data obtained during an earlier expedition in 1972. However, the 1972 sampling may have been incomplete, as it was performed by professional divers who were not... |
