n. sp.

Lithobubaris leviorum n. sp.

( Fig. 3B, C View FIG )

Lithobubaris tenens – Van Soest & Stentoft 1988: 72, fig. 35 (not: L. tenens Vacelet, 1959 )

HOLOTYPE. — Off Paynes Bay . Barbados, 216 m ( ZMA POR5265 View Materials ).

ETYMOLOGY. — Named after Claude and Pierrette Lévi in recognition of their contributions towards the elucidation of deep-water sponges.

DISTRIBUTION. — Barbados, Caribbean, encrusting dead lithistids and corals in deep water.


Thinly encrusting, round patches on dead corals and lithistid remains, appearing as a “hairy” crust; size several cm 2. Colour (dry) grey.


Huge single styles erect on a basal interlocked mass of desmas which overlies the substratum. Desmas arranged loosely, zygosis not well-developed. Style bases fit into the circular outcrops of branches of the desmas.


Desmas with circular side holes ( Fig. 3B, C View FIG ), covered with smoothly rounded swellings and tubercles, dimensions: diameter of desma 150- 200 µm, thickness of branches 20-35 µm, diameter of holes 50-60 µm. Styles, robust, dimensions: only up to 1500 µm in length and 48-63 µm in thickness.


The Barbados specimen differs clearly from Mediterranean L. tenens in the size of the styles which are about half as short in the longest sizes. In view of the geographic separation it is likely the Caribbean material represents a separate species.
