| The late Eocene ‘soft’ sponge fauna of southern Australia is reconstructed based on disassociated spicules and is used to interpret the paleoecology and environmental context of shallow marine communities in this region. The reconstructed sponge association was compared with coeval sponge assemblages from the Oamaru Diatomite, New Zealand, and with the modern ‘soft’ sponge fauna of southern coastal of Australia. Based on the predominance of shallow- and moderately shallow-water species, the late Eocene assemblage is interpreted to have inhabited waters depths of about 100 m. This contrast with the spicule assemblage from New Zealand, which characterized deeper waters based on the presence of numerous strictly deepwater sponge taxa, and the absence of... |

| Various records of A. simplex Carter, 1879 from the Atlantic are assigned to three new species of the sponge genus Asteropus Sollas, 1888, viz.: A. brasiliensis sp. n., A. vasiformis sp. n., and A. niger sp. n., whereas A. simplex s.s. is restricted to the Indo- Pacific. A worldwide study of Asteropus specimens resulted in the conclusion that two species groups exist, namely “simplex”- like species (with true sanidasters), and “sarasinorum”-like species (with spiny microrhabds), as previously observed by Bergquist (1965, 1968). A newly discovered microsclere complement of trichodragmata in the first group strengthens the need for generic distinction of both lineages, and accordingly the name Melophlus Thiele, 1899 is reinstated for the “sarasinorum”... |

| Seven dictyoceratid sponge species were collected from the Gulf of Aqaba, Northern Red Sea. Two new species were recognized: Scalarispongia aqabaensis n. sp. and Spongia lesleighae n. sp. Five others belong to the known species, Fascaplysinopsis reticulata (Hentschel, 1912), Phyllospongia papyracea (Esper, 1806), Hyattella tubaria (Lendenfeld, 1889), Spongia arabica (Keller, 1889) and Spongia irregularis (Lendenfeld, 1889). Hyattella tubaria, considered a synonym of H. intestinalis Lamarck, 1814) by Cook & Bergquist (2002) is demonstrated to be a valid species. Specimens are described and illustrated by photographs of preserved specimens and microphotographs of sections. |

| 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... |
