A new species of the sponge Raspailia (Raspaxilla) (Porifera : Demospongiae : Axinellida : Raspailiidae) from deep seamounts of the Western Pacific Ekins, M. /Debitus, Cécile Erpenbeck, D. Hooper, J. N. A. Raspailia Raspaxilla Aulospongus Seamounts Norfolk New Caledonia rhabdostyles A new species of Raspailia (Raspaxilla) frondosa sp. nov. is described from the deep seamounts of the Norfolk and New Caledonia Ridges. The morphology of the species resembles that of a frond or a fern, and its unique highly compressed axial skeleton of interlaced spongin fibres without spicules in combination with a radial extra axial skeleton of a perpendicular palisade of spicules, differentiate it from all other species of the subgenus. This species is compared morphologically to all 18 other valid species described in Raspailia (Raspaxilla). 2018 text https://www.documentation.ird.fr/hor/fdi:010072780 fdi:010072780 Ekins M., Debitus Cécile, Erpenbeck D., Hooper J.
