In a survey of the fauna inhabiting fallen wood in Rhizophora-dominated forests of an archipelago of small islands to thesouth of Sulawesi, in Indonesia, four species of limnoriid (Limnoria insulae, L. pfefferi, L. sellifera new species and L.unicornis) were found feeding on the wood. L. sellifera is characterised by a saddle-shaped pleotelson that is smaller thanpleonite 5, transverse rows of teeth-like tubercles dorsomedially on pleonites 2–4 and a uropod with relatively small ex-opod, two rows of pointed tubercles on the peduncle, and one row on the endopod. L. sellifera is the second species ofLimnoria to be found exclusively on mangrove wood. The cephalon and pereon of the four species of limnoriids are anatomically similar, but they differ markedly in features of pleonite 5, the pleotelson and the uropods.

Leptochelia Vatulelensis(Crustacea: Tanaidacea), A New Species From Anchialine Caves of the South-Western PacificLeptochelia vatulelensisn. sp., discovered on the small islands of Vatulele (Fijian group) and Ouvéa (Loyalty Islands, New Caledonia), is described and illustrated. The new species is distinguished from the others of the"Leptochelia-dubiagroup" (to which it is generally similar) by the following combination of morphological characteristics: (1) the presence of three to four distal setae on the maxilliped basis; (2) merus of pereopods III and IV with only a distosternal seta; (3) endopod of the uropods formed of four (rarely three) articles; (4) males with two (sometimes three) relatively short aesthetascs on the first five articles of the antennular flagellum; (5) male cheliped with a diminished dimorphism; (6) males with a vertical comb-row of setae on the cheliped propodus. Although it inhabits inland, anchialine caves, the new species lacks morphological features that are characteristic of some cave species.

Mangroves create unique ecological environments, furnishing a habitat opportunity for many species. The majority of published information on mangrove sponges comes from the Caribbean while few data are available from Indo-Pacific mangrove sponges. In general, species diversity of sponges in mangroves is lower than adjacent subtidal habitats in both the Caribbean and Indo-Pacific. The aim of this study is to report the first data about sponge species diversity of two mangrove forests from Bangka Island (North Sulawesi, Indonesia) and to describe a new sponge species associated with the mangroves. The survey found 19 species, belonging to 11 families and 15 genera; the samples were collected on mangrove trunks, on the roots or on the surrounding bottom. The majority of the species are typical of coral reef but two of them have been previously found only in lagoons or in mangrove habitats. These new data enlarge our knowledge about Indonesian sponges diversity and suggest the urgency to consider Indonesian mangroves as an important but underestimated element in coral reef ecological dynamics.

A new species of Ripiphoridae Gemminger & Harold, 1870, Archaeoripiphorus nuwa gen. et sp. nov., is described and illustrated from a well-preserved impression fossil from the Middle Jurassic Jiulongshan Formation collected at Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China, representing the oldest documented occurrence of the Ripiphoridae described from the Mesozoic era. It shares several characters belonging to two basal ripiphorid subfamilies (Pelecotominae and Ptilophorinae), but it cannot be attributed to either of them and is herein placed as Subfamily incertae sedis. An overall similarity between Archaeoripiphorus gen. nov. and Recent Pelecotominae and the occurrence of wood-boring beetles in the same Formation implies a similar parasitoid host preference in xylophagous beetles for A. nuwa gen. et sp. nov., putting a spotlight on a potential host-parasitoid relationship in the Mesozoic.

Mangrove forests are dynamic systems primarily confined to tropical and subtropical coastal regions. Mangroves are highly complex habitats sustaining a diverse array of terrestrial and aquatic fungal species. Endophytic fungi are widely distributed in mangrove ecosystems and are integral contributors to global biodiversity. Neopestalotiopsis species occur as endophytes, saprobes and opportunistic pathogens of many plant hosts. Herein, a new species of Neopestalotiopsis, N. alpapicalis, was collected from the mangrove trees Rhizophora apiculata and Rhizophora mucronata, in Krabi, Thailand. Morphological features conform to those of Neopestalotiopsis. Number of apical appendages and size of apical cells of the newly described species differ from those of phylogenetically related species. A combined dataset of ITS, β-tub and TEF1 genes was used to infer the phylogenetic placement of the new species. The two strains of novel species, N. alpapicalis clustered together and have a close affinity to N. rosicola.

ABSTRACT A new species of Sarcofahrtiopsis Hall, 1933, S. terezinhae sp. nov., is described based on male specimens collected in traps baited with rotting crabs in a mangrove forest in the state of Pará, eastern Brazilian Amazon. This species differs from congeneric species in having vesica with a row of toe-like projections. We provide a key to the species of the genus.

Abstract A new species of Colura (Dumort.) Dumort., was collected in the Cape Tribulation area of Queensland, in the mangrove forests of Daintree National Park. It is a member of subgenus Colura, section Harmophyllum Grolle, and differs from the superficially similar Colura pulcherrima Ast and C. queenslandica B. M. Thiers (both belong to another subgenus or section) by its easily detachable valve or by its acutely papillose lobule surface. Cheilolejeunea occlusa (Herz.) Kodama & Kitagawa occurs in the same habitat. This is a new record for Australia.

A new species of the laelapid mite genus Gaeolaelaps Evans & Till, G. tuberculatus sp. nov., is described from female specimens collected in soil and rotten leaves under citrus trees in Mazandaran province, northern Iran. Supplementary information on G. deinos (Zeman) is presented. Gaeolaelaps schusteri (Hirschmann) is redescribed based on the type specimens as well as additional specimens collected from the littoral zone of mangrove forests in Qeshm Island, in the eastern part of the Persian Gulf, southern Iran.

This paper has been written in response to a request for determinations of certain parasites of wood-boring beetles in Queensland, Australia. The description of a new species of Monolexis entailed rather more research than was expected and has led to the expression of a few opinions of an exploratory nature on the status of the subfamily Hecabolinae. Altogether one new species in the Doryctinae and six (including one new genus) in the Hecabolinae are described.The types of all new species are in the British Museum.

Deep-sea organisms are generally considered to be restricted to the great ocean depths, unable to enter shallower habitats except perhaps at the isothermic polar latitudes, due to physiological constraints, or more intense biotic interactions. Wood-boring bivalves ofXylophaga, however, are here shown to be exceptional. A clade, formally recognized by Turner in 2002, united by the derived characters of a complex mesoplax and a truncated excurrent siphon, papillose incurrent siphon with a longitudinal dorsal trough bordered by lappets, and often carrying white or glass-like granules, occurs at significantly shallower and warmer depths than do other species of the genus. Here, description of the new speciesX. multichelafrom 106 m depth off the Pacific coast of Guatemala illustrates the characters that unite the clade. Because wood-boring bivalves face intense competition and high levels of predation at depths of 2200 to 3250 m, they may not perceive biotic interactions at shallower depths to be dramatically more intense. In addition, members of this group are hypothesized to tolerate reduced oxygen availability, a requisite if animals are to occur in warm waters.
