HOLOTYPE. — New Caledonian Slope ( MNHN DCL 2787 About MNHN ).

MATERIAL EXAMINED ( Table 1). — Jumeau-East, 278- 410 m ( QM G318549, QM G318706).

DESCRIPTION

Growth form

Massive vase-shaped and pedunculate, 3 cm high, 2 cm wide at vase opening and 1.5 cm broad at base.

Colour

Blue to light grey in etoh.

Oscules

Not visible.

Schlacher-Hoenlinger M. A. et al.

Texture

Hard, stony.

Surface ornamentation

Smooth, slightly sculptured at the rim of the vase.

Ectosomal skeleton

E c t o s o m a l s p i c u l e s a r e a c a n t h o s t r o n g y l e s/ rhabds which form a tangential layer on the surface.

Choanosomal skeleton

Extremely dense choanosomal skeleton of rhizoclone desmas.

Megascleres

Desmas branched, thorny rhizoclone, with numerous short, blunt rays: 250-300 µm/20-40 µm.

Microscleres

Microrhabds (acanthose): 43.7-68.3 × 5.5-6.46 µm. Sigmaspires (curved, not very abundant): 9.1- 11.3 × 1.27-1.65 µm.

REMARKS

Our specimens agree well with the holotype, in morphology as well as geometry and size of spicules. The species has been previously recorded from the slope off New Caledonia.

Family CORALLISTIDAE Sollas, 1888 DEFINITION. — Polymorphic lithistids with dicranoclone choanosomal desmas and ectosomal dichotriaenes; microscleres are spirasters (usually two types), streptasters/amphiasters, microxeas and microstrongyles (Pisera F Lévi 2002b).
