Revision of the genusPsammocinia(Porifera: Demospongiae: Dictyoceratida), with six new species from New Zealand

Abstract: The status of species within the dictyoceratid sponge genus Psammocinia is reviewed. The separation of Psammocinia species from the closely related Ircinia species, which has been the subject of some dispute, is clarified. This distinction made on the basis of morphological evidence is supported by the limited chemotaxonomic and molecular phylogenetic data available. Six new species of Psammocinia are described from the New Zealand region.

“…The morphogenetic processes of the fibrous complex layout in I. retidermata , driven by specialized cells as secretion of the fiber innermost part (pith) and consequent bark construction/assembling from the inside to the outside of the fiber, matches fibers morphogenesis reported for other Keratosa species (Bergquist, 1978 ; Bergquist et al, 1998 ; De Cook & Bergquist, 1998 ; Gaino, 2011 ; Minchin, 1900 ; Schulze, 1878a , 1878b , 1879a , 1879b ; Simpson, 1984 ; Teragawa, 1986a , 1986b ; Vacelet, 1971 ; von Lendenfeld, 1889 ). Fiber morphogenesis diverges in depth when comparing I. retidermata versus S. spinosulus as revealed by SEM and LM.…”

“…The data presented here on the morphogenetic process match those of other soft sponges of the order Dictyoceratida, that is, fibers are synthesized by discrete groups of specialized cells that also drive their assembling. In I. retidermata the secretion of the innermost part of the fibers start around grains by conjoint action of spongocytes with a construction occurring by apposition from inside to outside as first shown by Schulze (1878aSchulze ( , 1878bSchulze ( , 1879aSchulze ( , 1879b and von Lendenfeld (1889) and as subsequently reported by several authors for various taxa (Bergquist, 1978;Bergquist et al, 1998;De Cook & Bergquist, 1998;Gaino, 2011;Minchin, 1900;Simpson, 1984;Teragawa, 1986aTeragawa, , 1986bVacelet, 1971).…”
