Scuba-mediated collecting and photography was undertaken within depth zones at 10 sites on four pre-1977 lava beds and those formed in 1977, 2002, 2004 and 2007. Sponges (23 species in 18 genera and 17 families), octocorals (20 species in 9 genera and 5 families) and ascidians (4 species in 4 genera and 2 families) were identified and these were differentially distributed in terms of lava bed age but not depth. Older lava formations had a greater biotic density and diversity, and colonisation of the lava beds appeared to be slow. The benthic fauna differed from that on the west coast of Reunion and the octocoral diversity was impoverished relative to published records elsewhere in the region. These characteristics of the benthos were attributed primarily to harshness of the lava reef, abrasive nature of the associated sediment and the turbulent sea conditions.

Y. Benayahu, 14 Jul. 1999. <i>Diagnosis. –</i> The holotype is a stalked colony, with a maximum cross-section of 2 × 4 cm and 5 cm high (Fig. 1a). The polypary consists in densely placed lobes that bear lobules with a rounded tip. Some of the polyps are partially retracted and visible on the surface of the lobules. The polyps have a collaret and eight points. The point sclerites have poorly developed heads, up to 0.19 mm long (Fig. 2a). The collaret spindles are slightly bent, 0.13–0.24 mm long, featuring sparse tubercles on their surface (Fig. 2b). The surface layer of the lobules has <i>leptoclados</i> - type clubs, 0.10–0.26 mm long, whose heads mostly feature pointed leaf-like processes (Fig. 2c). In addition, there are clubs, up to 0.24 mm long, with heads featuring a prominent warty ornamentation (Fig. 3a), and others that are even longer, up to 0.38 mm (Fig. 3b). The surface of the lobes has spindles, up to 0.51 mm long, with warty tubercles that are occasionally more common at one end of the spindle than the other (Fig. 3c). The clubs with leaf-like processes on the surface layer of the colony base are 0.10–0.17 mm long (Fig. 4a). They have wider handles and are shorter compared to those of the lobules' surface. Some of these clubs, up to 0.30 mm long, feature heads with a warty ornamentation (Fig.4b, c). In addition, there are capstan-like sclerites, 0.10–0.16 mm long (Fig. 4d). The spindles of the surface of the base are shorter than those of the surface of the lobes, up to 0.37 mm long (Fig. 4e). The interior of the lobules has spindles, up to 1.95 mm long, some bent and with a side branch (Fig. 3d). Most of the spindles have sparsely dispersed small tubercles (Fig. 3e), but a few have more densely located and larger ones (Fig. 3f). The spindles in the interior of the base are up 1.90 mm long (Fi [...]
