Revision of Microcionidae (Porifera: Poecilosclerida: Demospongiae), with description of Australian species
A phylogenctic revision of the poccilosclcrid Microcionidae is based on type material, the
worldwide literature, and comprehensive Australian collections. Of 73 available generic
names 7 genera and 12 subgenera are recognised here. Of 561 available species names 455 are considered valid (1 virtually unrecognisable), including 52 new species. The Australian fauna, including Australian Antarctic Territory, contains 148 species (31 new), many new records, most are new combinations, and many illustrated for the first time. A synonymy of world species is provided. Valid taxa include: Clalhria (with 7 subgenera: C (Clathria) (with 31 Ausiralian species, S2 other species worldwide, with new species murphyi, noarlungae, biclathrata, borealis, burioni, sarai. sarospinifera). C. ( Wilsonella) (6, 8, abrolhosensis, ensiae, lindgreni spp. nov.), C. (Microciona) (5, 91. illawarrae, lizardensis. simae, brondstedi. campecheae. ciaudei, hentscheli, leighensis, stephensae, tunisiae, urizae, vacelettia spp. nov.), C {Dendrocia) (7 species endemic to Australia), C. (Axociella) (6. 6, patula, fromontae. georgiaensis spp. nov.), C. (Isoociella) (4, 1, selachia* skia spp. nov.), and C (Thalysias) (36, 53, aphylla, craspedia, darwinensis, fusterna, hallmanni, hesperia, lematolae. phorbasiformis, styloprothesis, tingens, wesselensis, amiranteiensis, hechteli spp. nov.); Antho (with 3 subgenera: A. (Antho) (12, 10), A. (Plocamia) (2, 17) and A, ilsopentctya) (3.1. punuea, saintvincenti spp. nov.); Echinoiiathria (14, 15. bergquistae, levii, notialis, parkeri. riddlei spp. nov.); Holopsamma (9 species endemic to Australia, I indeterminate species); Echinochulina (with 2 subgenera: E iFjiiinochalina) (10, 2, felhi sp. nov,), £ (Protttphlifo spongio) (8 species endemic to Australia and New Caledonia, callata, favulosa, isitaci, tuberosa spp. nov.)); Artemisimi (4, 10); and Pandoras (incertae sedis) (0, 2"), Generic keys are provided. Morphometric characters of primary importance include the origin, geometry and distribution of structural meg3scleres within the skeleton, modification of megasclercs to monactinal or diactinal forms, the presence or absence of a specialised ectosomal skeleton, presence of detritus incorporated into spongin fibres, and overall skeletal structure (including compression of the axial skeleton and differentiation of axial and extra-axial regions). Brief zoogeographical comparisons are made between continental Australian and adjacent Indo-west Pacific faunas. Australian species comprise about 32% of the world's microcionid diversity; about 75% of species arc endemic for the Australian region, and temperate species (81 %.) have higher levels of endemism than tropical species{59%).
