Summary: | Genus Radiella Schmidt, 1870 Diagnosis (emended from BouryEsnault 2002): Sponges are circular, lenticular or hemispherical. The inhalant and exhalant apertures are grouped on papillae. The choanosomal skeleton is composed of diverging tracts of principal spicules emanating from a central nucleus at the sponge base and by groups of fusiform tylostyles. The skeleton of the lower surface is constituted by an envelope of principal subtylostyles or styles covered by a thin palisade of cortical tylostyles. The upper surface is composed of one or two layers of tylostyles. A fringe of additional spicules is observed at the border between the upper and the lower surface. Emendation: The presence of a marginal fringe is added. Type species: Radiella sol Schmidt, 1870 (by subsequent designation). Published as part of Plotkin, Alexander S. & Janussen, Dorte, 2008, Polymastiidae and Suberitidae (Porifera: Demospongiae: Hadromerida) of the deep Weddell Sea, Antarctic *, pp. 95-135 in Zootaxa 1866 on page 111, DOI:10.5281/zenodo.183878 |
