Material examined

PONTA DO OURO • two fragments of about 5×2 ×2 and 6 ×3× 3 cm; 26°49′17.512″ S, 32°53′42.514″ E; Kev’s; 23.4 m deep; 3 Feb. 2017; Cerrano leg.; PO4 GoogleMaps   1 spec.; Jenny’s Paradise; 26°46′50.336″ S, 32°54′12.329″ E; 17.8 m deep; 12 Apr. 2017; Cerrano leg.; PO97 GoogleMaps   .

Description

The live specimens are massively encrusting ( Fig. 3A View Fig ) or massively, irregularly spherical ( Fig. 3B View Fig ). They have an uneven surface with scattered, small, sharp conules and prominent oscula ( Fig. 3B View Fig ). The

live sponge is light yellow ( Fig. 3 View Fig A–B); the alcohol-preserved specimens become dark purple, and have a smooth and irregular surface. The consistence is tough.

SKELETON. Spongin fibers scarcely developed, the choanosome is collagenous.

Remarks

The specimens belong to the genus Pseudoceratina Carter, 1885   due to the fibrous, dendritic skeleton and to the dense and collagenous matrix. There are four valid species in this genus, all with an Indo- Pacific distribution ( Van Soest et al. 2019). Pseudoceratina arabica ( Keller, 1889)   contains abundant fibers and is characterized by high conules; P. durissima Carter, 1885   has been recorded in south-east Australia and shows a blue-black live color, with a smooth surface. Pseudoceratina verrucosa Bergquist, 1995   differs in its strongly verrucose surface and thicker fibers.

The specimens fit perfectly with the original description of Pseudoceratina purpurea ( Carter, 1880)   in the general morphology and in the scarcely developed fibers. More recent, complete description and illustrations are available in Bergquist (1965: 135, fig. 6, as Psammaplysilla purpurea   ).

The species is widely distributed in the Indo-Pacific Ocean and has been already recorded in Madagascar ( Vacelet et al. 1976).
