A new Suberites (Demospongiae: Hadromerida: Suberitidae) from the tropical Indo-West Pacific Naturalis
Becking, L.E.; Lim, S.C..
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...

Haliclona (Halichoclona) vansoesti n. sp., a new chalinid sponge species (Porifera, Demospongiae, Haplosclerida) from the Caribbean Naturalis
Weerdt, Wallie H. de; Kluijver, Mario J. de; Gomez, Raquel.
A new sponge species, Haliclona (Halichoclona) vansoesti n.sp., belonging to the family Chalinidae of the order Haplosclerida, is described from Curaçao and other Caribbean localities. The subgenus name Halichoclona de Laubenfels is for the first time applied to a species of the “fistulosa” group ( “Pellina” of authors), one of eight species groups which came out as monophyletic groups during an earlier phylogenetic analysis of the genus Haliclona. Justification for devoting a separate paper to a single species follows from recent findings of interesting secondary metabolites produced by this sponge. Chemistry and cell biology research necessitates to have a proper name for the species available.

Latrunculia oparinae n. sp. (Demospongiae, Poecilosclerida, Latrunculiidae) from the Kurile Islands, Sea of Okhotsk, Russia Naturalis
Samaai, Toufiek; Krasokhin, Vladimir.
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...

A remarkable new Middle Sandbian (Ordovician) hexactinellid sponge in Baltic erratics Naturalis
Botting, J.P.; Rhebergen, F..
A new species of complex hexactinellid sponge, Haljalaspongia inaudita, is described from fluvially transported blocks found in northwestern Germany, near the Dutch border, but which probably originated from the eastern Baltic region. The heavily folded wall is composed of multiple spicule layers, including dermal and gastral layers of acanthohexactines, and a central layer of sub-parallel monaxons. The monaxial layer is lined on one side by a reticulate array of smooth monaxons. The sponge is difficult to assign to any known fossil or recent group, but shares some features with the dictyospongioid family Docodermatidae.

A monograph of the shallow-water Chalinidae (Porifera, Haplosclerida) of the Caribbean Naturalis
Weerdt, Wallie H. de.
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...

A new sponge Desmapsamma vervoorti spec. nov. (Poecilosclerida: Desmacididae) from Indonesia Naturalis
Soest, R.W.M. van.
A new poecilosclerid sponge species Desmapsamma vervoorti spec. nov. is described from several Indonesian localities: Ambon, Jedan, Salayar, Komodo, Java, and Irian Jaya. The species was earlier reported from several Indo-Pacific localities as D. anchorata (Carter, 1882), a common Caribbean shallow water species. Comparison with Caribbean specimens makes it clear that Indo-Pacific specimens demonstrate small but consistent differences.

The Northeastern Atlantic species Mycale micracanthoxea Buizer & Van Soest, 1977 (Porifera, Poecilosclerida) in the Strait of Gibraltar (Southern Spain) Naturalis
Carballo, J.L.; García-Gómez, J.C..
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.

Evaluation of the ecological function of amphitoxin in the reef-dwelling sponge Callyspongia (Euplacella) biru (Haplosclerida: Callyspongiidae) at southwest Sulawesi, Indonesia Naturalis
Voogd, N.J. de; Haftka, J.J.H.; Hoeksema, B.W..
The ecological function of the secondary metabolite amphitoxin produced by Callyspongia (Euplacella) biru is evaluated by a forced confrontation with the free-living scleractinian coral Fungia fungites at different exposure times. Our major goal was to determine whether such a forced confrontation with a spatial com­petitor would cause a significant change in the concentration of amphitoxin in the sponge tissue, indicating a regulatory mechanism of amphitoxin production. Firstly, the concentrations of amphitoxin of sponge fragments submitted to forced confrontation with a mushroom coral did not differ between the exposure times. Secondly, all sponge fragments, including the controls had a consistently lower amphitoxin concentration during the course of the...

Amphimedon denhartogi spec. nov. (Porifera: Haplosclerida) from deep reef habitats in Indonesia Naturalis
Voogd, N.J. de.
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 beta diversity in the Spermonde Archipelago, SW Sulawesi, Indonesia Naturalis
Voogd, N.J. de; Cleary, D.F.R.; Hoeksema, B.W.; Noor, A.; Soest, R.W.M. van.
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...

Voogd, N.J. de; Parra-Velandia, F.J.; Soest, R.W.M. van.
Agelas linnaei spec.nov. (Porifera: Demospongiae: Agelasida: Agelasidae) is described from the Thousands Islands reef complex, West- Java, Indonesia. The new species is compared with all other Agelas species occurring in the Indo-West Pacific region. The new species differs from these other species by the overall morphology and the size of the verticillated acanthostyles. Surprisingly, this is only the second Agelas species ever described from Indonesia.

Callyspongia (Euplacella) biru spec. nov. (Porifera: Demospongiae: Haplosclerida) from Indonesia Naturalis
Voogd, N.J. de.
A new sponge species Callyspongia (Euplacella) biru spec. nov. is described from various locations within Indonesia (NE Bali, SW & NE Sulawesi and NE Kalimantan). The species is assigned to the subgenus Euplacella of the genus Callyspongia because it has brushes of spicules on the nodes of its double-meshed ectosomal skeleton. The species is discussed and compared with relevant Callyspongia records from other Indonesian and neighbouring Indo-Pacific areas.

A new species of Biemna (Porifera, Poecilosclerida) from the Sultanate of Oman Naturalis
Soest, R.W.M. van; Beglinger, E.J..
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...

Phylogeography, genetic diversity and structure of the poecilosclerid sponge Phorbas fictitius at oceanic islands Naturalis
Xavier, J.R.; Soest, R.W.M. van; Breeuwer, J.A.J.; Martins, A.M.F.; Menken, S.B.J..
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...
