Some of the deck images indicate long diactins projecting sparsely, up to 14 mm, from the dermal surface, but these may be foreign in origin; we have not found such large diactins in the material available for examination. Dimensions of the holotype are ~ 6 cm in total length, including the stalk of 1.8 cm length (Fig.

Choanosomal skeleton consists of a loose, vacuolar network of thin choanosomal diactins, large choanosomal hexactins and the thicker proximal rays of the hypodermal pentactins. There is no evidence of fusion between any spicules. Microscleres are scattered evenly throughout the choanosome. Ectosomal skeleton of the dermal side consists of abundant prostal pentactins providing good support for the sturdy lattice of stauractine (60.0% of 315 assessed), pentactine (38.4%), and rare hexactine (1.64%) dermalia. The atrial ectosome lacks hypoatrial pentactins but has bands of diactins that provide poor support for the atrial lattice of mainly hexactins (86.4% of 118 assessed), pentactins (7.5%), and stauractins (5.1%). Microscleres are present as in the choanosome.

) and hemioxyhexasters have very short, sparsely spined or smooth, thick primary rays, ending in swollen hemispheres; 1-7, usually 3-4, rough, straight, terminal rays tapering to pointed tips emanate from the margins and occasionally from the centre of the hemisphere. Short to very short spur-like terminal rays are common. Anisodiscohexasters (Fig.

) have smooth primary rays ending in ovoid strobila. Each strobilum supports ca. 20-30 rough, curved terminal rays that end in discs with 4-7 marginal discs. The tuft of terminal rays from each primary ray varies in length of rays, and with ray length the diameter of terminal discs, in a pattern that is not yet clear, but the whole spicule resembles a radially symmetrical starburst.
