Natural deposits of sunken wood provide an important habitat for deep-sea invertebrates. Deep-sea chitons in the primitiveorder Lepidopleurida are typically collected rarely and as single specimens. However, these animals have been recoveredin large densities associated with sunken wood in the tropical West Pacific, in groups of up to 50 individuals. Four deep-sea expeditions in the West Pacific, to the Philippines, Solomon Islands, and Vanuatu, recovered a large number of poly-placophorans. We have examined the morphology as well as the range and distribution of these species, based on the larg-est collection ever examined (more than 1300 individuals). These species show potentially adapted characters associatedwith exploitation of sunken wood as habitat, such as protruding caps on sensory shell pores (aesthetes) and large interseg-mental bristles with potential sensory function. In this study we investigated the twenty-two species recovered, includingseven newly described here (Leptochiton consimilis n. sp., L. angustidens n. sp., L. dykei n. sp., L. samadiae n. sp., L.longisetosus n. sp., L. clarki n. sp., L. schwabei n. sp.), and provide the first identification key to the 34 lepidopleuran chitons known from sunken wood worldwide.

The four named species of Branchipolynoe all live symbiotically in mytilid mussels (Bathymodiolus) that occur at hydrothermal vents or methane seeps. Analyses using mitochondrial (COI and 16S) and nuclear (ITS) genes, as well as morphology, were conducted on a collection of Branchipolynoe from Pacific Costa Rican methane seeps and West Pacific hydrothermal vents. This revealed five new species of Branchipolynoe, and these are formally described. The new species from Costa Rica live in three species of Bathymodiolus mussels (also new) at depths ranging from 1000 to 1800 m. Branchipolynoe kajsae n. sp. and Branchipolynoe halliseyae n. sp. were found in all three undescribed Bathymodiolus species, while Branchipolynoe eliseae n. sp. was found in Bathymodiolus spp. 1 and 2, and Branchipolynoe meridae n. sp. was found in Bathymodiolus spp. 1 and 3. Hence, Bathymodiolus sp. 1 hosted all four of the new species, while the other two Bathymodiolus hosted three each. Most mussels contained only one specimen of Branchipolynoe; where there was more than one, these were often a female and smaller male of the same species. The newly discovered species from the West Pacific, Branchipolynoe tjiasmantoi n. sp., lives in unidentified Bathymodiolus at depths ranging from 674 to 2657 m from hydrothermal vents in the North Fiji (Fiji) and Lau Basins (Tonga) and also from New Zealand, Vanuatu, and the Manus Basin (Papua New Guinea). The phylogenetic and biogeographical implications of this diversity of Branchipolynoe are discussed.

Three new species of the gekkonid genus Cyrtodactylus are described from Peninsular Malaysia; C. jarakensis sp. nov. from Pulau Jarak off the west coast of Perak, C. batucolus sp. nov. from Pulau Besar of the Water Islands Archipelago off the west coast of Melaka, and C. pantiensis sp. nov. from the Gunung Panti Forest Reserve, Johor. All are distinguishable from other Sunda Shelf species of Cyrtodactylus in having unique combinations of morphological and color pattern characteristics. The continued high potential for finding additional new species in unexplored regions of southern Peninsular Malaysia and its associated archipelagos is further supported with these findings.

Two new species of the family Leptochitonidae, Leptochiton pumilus sp. nov. and Terenochiton nomurai sp. nov. are described from the tropical and subtropical shallow waters of the West Pacific. L. pumilus from the Philippines and Papua New Guinea has a net-like sculpture on the shell which is rather rare feature in the genus. In this genus, so far only three species have hitherto been known in the tropical shallow waters, in contrast to more than 130 other extant species which are living in the deep cold waters and high latitudes. T. nomurai from Ryukyu Islands is the second representative of the genus Terenochiton Iredale, 1914 which was recently reinstated for Leptochiton norfolcensis (Hedley et Hull, 1912), and is characterized by having rudiments of the insertion plates in all valves. T. nomurai closely resembles the type species, but differs in the arrangement of the aesthete pores on the granules of the tegmentum, and less developed rudiments of the insertion plates. Key words: chitons, Leptochiton, Terenochiton, new species, the Philippines, Japan, Papua New Guinea. Описаны два новых вида семейства Leptochitonidae, Leptochiton pumilus sp. nov. и Terenochiton nomurai sp. nov. из тропических и субтропических мелководий западной Пацифики. L. pumilus c Филиппин и Папуа – Новой Гвинеи имеет сетчатовидную скульптуру на раковине, что является довольно редким признаком в этом роде. В этом роде только три вида известны до настоящего времени в тропических мелководьях, в противоположность более чем 130 другим современным видам, которые живут в глубоких холодных водах и в высоких широтах. T. nomurai из островов Рюкю является вторым представителем рода Terenochiton Iredale, 1914, который был недавно восстановлен для Leptochiton norfolcensis (Hedley et Hull, 1912) и характеризуется наличием рудиментов инсерционных пластинок на всех щитках. T. nomurai сходен с типовым видом рода, но отличается расположением пор эстетов на зернах тегментума и менее развитыми рудиментами инсерционных пластинок. Ключевые слова: хитоны, Leptochiton, Terenochiton, новые виды, Филиппины, Япония, Папуа Новая Гвинея.

A review of the West African “snail-killing flies” or “marsh flies” (Sciomyzidae) shows that the fauna is not as dominated by the generally aquatic, predaceous genus Sepedon as was previously considered. Twenty species in seven genera, including three new species, Colobaea occidentalis, Pteromicra zariae and Sepedonella castanea are recorded. The Holarctic-Oriental genera Colobaea and Pteromicra are documented from Africa south of the Sahara for the first time. Biogeographical analyses based on the discovery of “Palaearctic” genera of Diptera south of the Sahara, faunal connections, and dispersal routes are presented. A key for identification and illustrations of diagnostic characters for some species are included.
