The adult male of Centropages orsinii Giesbrecht, 1889 is redescribed based on a single specimen collected in an anchialine cave on the island of Espiritu Santo in Vanuatu. The mouthparts of this species have never previously been described and figured. Males exhibit a remarkable asymmetry in the form of the basis of leg 4. On the right leg only the basis carries three processes on its posterior surface, a unique asymmetry for the entire Calanoida. Comparison with males from other locations in the Indo-Pacific reveals some variation in the precise form of these processes. Some other species of Centropages exhibit sexually dimorphic asymmetry, with modified setation elements present on the exopod of right leg 4 only in males. It is speculated that this might be correlated with the strong asymmetry exhibited in females of some species within the genus. © Publications Scientifiques du Muséum national d'Histoire naturelle, Paris.

ABSTRACT Xylophion sevrapek Villemant n. sp. (Insecta, Hymenoptera, Ichneumonidae) is described from Espiritu Santo, Vanuatu and compared to the two other described species of the genus, X. xylus (Gauld, 1977) and X. ketus (Gauld, 1977).

Four new skates of the genus Notoraja Ishiyama, 1958 are described from the rarely accessed, deep waters off New Caledonia, Vanuatu and Fiji islands, and the Norfolk Ridge. Three of these (N. alisae n. sp., N. longiventralis n. sp. and N. fijiensis n. sp.) are “velcro skates” which are characterised by their velvety dorsal and ventral surfaces, covered with fine denticles. Although similar in shape, they differ by their colour pattern, dermal armature, development of the lateral tail folds, and size of the pelvic-fin anterior lobe and nasal curtain. The description of the fourth species, Notoraja inusitata n. sp., is based on a juvenile male exhibiting some unusual features resembling those of other skate genera.

Pante E. & France S. C. 2010. — Pseudochrysogorgia bellona n. gen., n. sp.: a new genus and species of chrysogorgiid octocoral (Coelenterata, Anthozoa) from the Coral Sea. Zoosystema 32 (4) : 595-612.A new genus and species of deep-sea Chrysogorgiidae Verrill, 1883, Pseudochrysogorgia bellona n. gen. n. sp., is described from colonies collected in the Coral Sea, West of New Caledonia (southwestern Pacific Ocean). These specimens bear resemblance to the genera Chrysogorgia Duchassaing & Michelotti, 1864 (dichotomously-subdivided branches arising from the main stem in a spiraling fashion; polyps characterized by ornamented sclerites) and Metallogorgia Versluys, 1902 (colony monopodial, hexagonal branching pattern). Additional material collected North of New Zealand (Otara Seamount) is used to complete the description of this new genus. Its taxonomic rank is discussed in light of morphology- and DNA-based phylogenetic inference and analysis of genetic distances among deep-sea chrysogorgiid genera.

Zoosystema 32 (2): 259-265.A new genus and species, Kerkiratrobius rosanae n. gen., n. sp., is described and figured from males collected in the Corfu Island, Greece. The new genus has a special feature in its genitalia which permits its separation from all previously known genera of the order, and particularly other genera of the subfamily Petrobiinae to which it belongs.

Damborenea C. & Brusa F. 2009. — A new species of Temnosewellia (Platyhelminthes, Temnocephalida) ectosymbiont on Villopotamon thaii (Crustacea, Decapoda, Potamidae) from Vietnam. Zoosystema 31 (2): 321-332.A new species of the genus Temnosewellia (Platyhelminthes, Temnocephalida, Temnocephalidae), Temnosewellia vietnamensis n. sp., is described from Quangnam Province, Vietnam, ectosymbiont on the external carapace of Villopotamon thaii Dang & Ho, 2003 (Crustacea, Decapoda, Potamidae). Records of temnocephalans from the region of Southeast Asia are superficial despite a great number of potential host species. Temnosewellia semperi (Weber, 1889), is the only known species and has been recorded from Aru, Java, Sumatra, Philippines, Malaysia, Thailand and China. In 2003, temnocephalans were reported for the first time from Vietnam which led to the current description of a new species based largely on characters from adults and eggs. The new species has five anterior tentacles; black pigment confined to the eyes; an ejaculatory sac; a cirrus straight that is not dilated and which has an obvious distal unspined region; anterior parenchyma with only two Haswell cells; yellow, slightly reniform eggs, that lack a peduncle and which are deposited on host carapace. The opercular plates of the eggs form a ring of seven almost rectangular shapes. The fracture plane of the operculum is parallel to the long axis of the egg. The great number of potential host species available in the Southeast Asia is taken as evidence that the region may harbour many other, yet undescribed, temnocephalan species.
