Diagnosis
Bushy flabellate growth form. Surface rugose, conulose, and hispid. Choanosomal skeleton with two components: compressed, tightly reticulate axis cored by oxeas with spined points; radial peripheral region formed by columns of smooth anisoxeote spicules projecting outwards from axis. Echinating megascleres absent. Extra-axial skeleton radial, with tracts of long, thick, subectosomal styles embedded in the outer (radial) portion of the axis, ascending to surface and projecting through it. Ectosomal skeleton composed of peculiarly curved or sinuous toxiform styles with spined terminations, grouped around a central extra-axial style in a bouquet. Structural megascleres include oxeas with spined terminations, smooth anisoxeas, large styles or anisoxeas with rounded bases, and dermal flexuous toxiform styles with spined terminations. Microscleres absent.
