Thin lamellae or thin plates, foliate, with two different surface layers: upper surface smooth, regular, with numerous, evenly distributed oscules (Fig. 5A). Ectosomal skeleton a tangential layer of upper surface with one size regular small mesh ends of primary fibres echinated by free spicules (Fig. 5B, D). Inner surface irregularly undulated,ectosomal layer with small rounded mesh, without hispidation. Subectosomal region of upper surface exhibits three (in type specimen) (Fig. 5C)) successive ectosomal layers or ‘growth lines or lamellae’, Inner surface with single ectosomal layer. Choanosomal skeleton (Fig. 5D) of parallel paucispicular primary longitudinal fibres, nonramified, strongly cored with large spongin sheath, rounded to rectangular large empty choanosomal mesh, and short, non-ramified connecting unispicular fibres.
