In this paper we describe Suberites diversicolor spec. nov. (Porifera: Demospongiae: Hadromerida: Suberitidae) from four enclosed anchialine lakes located in Indonesia and from a confined system in Singapore. Initially this species was thought to be specific to anchialine lakes, but further comparison to coastal areas indicated that it is more widespread in inshore systems. We have used morphological characters to distinguish this species and a molecular marker to confirm that all types are the same species. Suberites diversicolor spec. nov. is encrusting or massive with small protrusions or larger globular branches. The external colour can be olive-green, blue, purple, red-orange, or orange-yellow. Suberites diversicolor spec. nov. differs from known... |

A new species of Latrunculia with unusual properties is described from Kurile Island, Sea of Okhotsk, Russia. Although this species is structurally very similar in choanosomal architecture to all known species of Latrunculia, it differs from other Latrunculia in both the structure of the anisodiscorhabd microscleres and by possessing terminally spined styles. It is the first Latrunculia to be described with terminally spined anisostyles. Furthermore, the characteristic anisodiscorhabds of this new species closely resemble microfossils found in Oligocene deposits from New Zealand. The similarity between the new species and the fossil New Zealand species, along with the strong differences in spiculation from other Latrunculia species, suggest a Tethyan... |

All known species of the sponge family Chalinidae (Demospongiae, Haplosclerida) occurring in the shallower part of the Caribbean are described and taxonomically revised. The study is the result of collecting activities of the author and others throughout the Caribbean, and examination of type and other material in musea and institutes. In a previous revision of north-eastern Atlantic Chalinidae (De Weerdt, 1986, 1989), the family was subdivided into eight monophyletic species groups, with various states of the skeletal architecture as main synapomorphous (shared derived) characters. After examination of all available type species of the nominal genera of the family, the species groups are now given proper names, replacing the tentative names in the earlier... |

The northeastern Atlantic species Mycale micracanthoxea Buizer & Van Soest, 1977 is a component of subtidal shallow water and brackishwater harbour poles and pontoons from The Netherlands, where it grows attached to shells, barnacles, etc. It was found in similar zones and habitats of Algeciras Bay (Gibraltar Strait, southern Spain) and Isla Cristina (Huelva, southern Spain) where it is very common. This new record constitutes the southernmost limit of the geographical range of this species. This article presents some data on the anatomical variability of Mycale micracanthoxea, along with a discussion on the possible causes of its observed distribution. |

Based on collections assembled by Dutch expeditions to the Northwest African region, including the offshore islands in the neighbouring Atlantic, a taxonomic monograph of sponges of the genus Mycale is presented. Additional material from the region borrowed from the Zoologisk Museum of the University of Copenhagen and incidental samples made by individual collectors were also included. The combined collections contained sixteen species, nine of which are new to science: Mycale (Aegogropila) syringosimilis spec. nov., Mycale (Aegogropila) tenerifensis spec. nov., Mycale (Arenochalina) africamucosa spec. nov., Mycale (Carmia) atropha spec. nov., Mycale (Carmia) guineensis spec. nov., Mycale (Naviculina) cruzi spec. nov., Mycale (Paresperella) janvermeuleni... |

A new sponge species Amphimedon denhartogi spec. nov., belonging to the family Niphatidae of the order Haplosclerida, is described from 3 localities in Indonesia: Tulamben (NE Bali), Siladen Island (NE Sulawesi) and Kambing Island (SW Sulawesi). Amphimedon denhartogi spec. nov. is characterised by its growth form of thinly flabellate branches, the occurrence of star-shaped oscules over one side of the sponge body, and by its small strongyles, and can hardly be confused with another species. All specimens were found in similar habitats, at around 40-45 m of depth on steep sandy slopes. |

Sponge assemblages were investigated in the Spermonde Archipelago, southwestern Sulawesi, Indonesia. In this study spatial patterns of sponge similarity among sites were significantly related to remotely sensed environmental variables, the degree of human settlement and depth, but not to the distance between sites. Both oviparous and viviparous species groups responded to similar environmental constraints, and differences in similarity were unrelated to the distance between sites. The degree of human settlement, however, was significantly related to variation in the composition of viviparous, but not oviparous species. Our results demonstrate, most importantly, the utility of remotely sensed data in predicting the spatial turnover of diverse species... |

Recent (1998) collecting off the coasts of Oman in the course of the EC-MAS3 funded ‘Symbiosponge’ project yielded three species of the genus Biemna Gray, 1867 (Demospongiae, Poecilosclerida, Mycalina, Desmacellidae) not previously known from the area. One of these appeared to be new to science and is described as Biemna omanensis n.sp.. Its distinguishing features comprise the possession of oxea megascleres, which is of rare occurrence in Biemna, and a full complement of microscleres including microxeas, sigmas, commata, all of which are divisible in two non-overlapping size categories, and raphides. One of the other two species conformed to an earlier described species Biemna ciocalyptoides Burton, 1959, which was discovered to be a junior synonym of... |

A new sponge species, Cladocroce burapha n. sp. (Chalinidae, Haplosclerida, Porifera), is described from Chonburi province, eastern coast of the Gulf of Thailand, Thailand. The new species can be separated from other Cladocroce species by a combination of characters, including growth form, form and size of the spicules, and habitat. This is the first record of the genus Cladocroce from Thailand. |

In this study we assessed the sequence variation in the I3-M11 partition of the mtDNA cytochrome c oxidase subunit I gene (COI) in ten populations of the Atlanto-Mediterranean demosponge Phorbas fictitius (Porifera: Poecilosclerida) at two spatial scales: a regional scale comparing mainland (Iberian) and insular (Macaronesian) populations, and a local (Archipelagic) scale focusing on different island populations of the Azores archipelago. A multiple approach combining diversity measures, FST estimates, phylogenetic inference and nested clade phylogeographic analysis was used to assess the genetic structure and elucidate the evolutionary history of this species. Genetic differentiation, based of FST estimates, was found among most populations at both scales... |
