Introduction
The Aplysinellidae Bergquist, 1980, are verongids with dendritic skeleton made up of fibres with both bark and pith elements represented, both components can vary in the relative proportion of the fibre section that they constitute. Some species exhibit a different surface to interior pigmentation in life which remains discernable in alcohol, this is unusual within the Verongida. Free fibrous spicules augment the fibre skeleton in one genus (Aplysinella). Fibre mass in relation to soft tissue volume varies from strongly fibrous (Porphyria), to predominance of collagenous matrix (Suberea). Choanocyte chambers are diplodal, small and spherical.
Three genera are included with distribution from the Red Sea, Indo-Pacific, Australian tropical and warm temperate regions. Several species now grouped within Aplysina and Pseudoceratina need to be transferred to aplysinellid genera, mainly to Suberea, but there is need for a comprehensive revision. Nine species are currently described in the family (Bergquist & Cook 2002).
