HABITUS. All of the specimens have a regular cylindrical shape (5–7 cm high, ca 1 cm in diameter) ( Fig. 3A View Fig ). Surface lightly hispid, consistence firm. Colour in life bright yellow ( Fig. 3A View Fig ).

SKELETON. Skeleton formed by network of thin ascending plurispicular fibres forming quadrangular meshes with abundant spongin ( Fig. 3B View Fig ). Choanosome differentiated in axial compressed region ( Fig. 3D View Fig ) and extra-axial plumoreticulate part ( Fig. 3 View Fig C–D). Ectosome formed by erect spicule brushes, hispidating sponge surface, supported by terminal part of choanosomal ascending fibres ( Fig. 3 View Fig C–D).

SPICULES. Megascleres: Styles smooth, straight or slightly curved, with regular, round heads ( Fig. 4A View Fig ), 700–(832.5)–960 μm long and 20–(25.2)–32.5 μm thick in holotype. Rhabdostyles smooth with pronounced basal bend ( Fig. 4B View Fig ), 240–(296.5)–435 μm long and 15–(17)–20 μm thick in holotype. Oxeas smooth, more or less folded, 197.5–(346)–425 μm long and 12.5–(18.7)–22.5 μm thick in holotype. The thinnest ones are almost straight or slightly flexuous ( Fig. 4C View Fig ). Measurements of spicule of all collected specimens (holotype and paratypes) are reported in Table 4.


This species lives on a rocky cliff covered by coralline algae, at a depth between 15 and 20 m.


We have recorded two new species of the genus Axinella and have therefore chosen to make a single discussion after their description.
