Ciocalypta heterostyla Hentschel, 1912: 424   , pl. 14, fig. 3, pl. 21, fig. 58.

Material examined

PONTA DO OURO • 1 fragment with some fistules and the basal portion, about 2 ×1× 1 cm; 26°49′55.65″ S, 32°53′13.41″ E; Three Sisters; 23.9 m deep; 21 Feb. 2017; Cerrano leg.; PO63 GoogleMaps   .

Description

The sponge is burrowed under the sediment and only its erect fistules are visible ( Fig. 24A View Fig ). These are whitish, transparent, showing the yellow, internal axis. The alcohol preserved sample is a thin massive base bearing fistules; the color is dirty white. The consistence is really soft and extremely compressible.

SKELETON. The skeleton of the basal part consists of multispicular tracts in confusion and grains of sediment ( Fig. 24B View Fig ). The skeleton of fistules ( Fig. 24C View Fig ) has a central axis of densely packed spicules, about 100 µm in section, close to the base, and gradually thinner towards the apex of the fistula. From the axis, multispicular fibers, 20–25 µm in section, develop, opening in fans close to the surface ( Fig. 24C View Fig ).

SPICULES. The styles are in a wide range of shapes (straight, slightly curved, sinuous) and size, 285– (351.5, 63.7)– 495 µm ×5–(8.3, 1.5)– 10 µm ( Fig. 24 View Fig D–E).

Remarks

The presence on the surface of numerous finger-shaped and transparent fistulae with a central axis and the general structure of the skeleton are typical features of the genus Ciocalypta Bowerbank, 1862   . To date, there are 26 species of Ciocalypta   described ( Van Soest et al. 2019). The specimen shares with Ciocalypta heterostyla Hentschel, 1912   the spicule size and shape, the skeleton organization and the

general morphology. This species is known from Indonesia and Arafura Sea ( Van Soest et al. 2019) and, therefore, this is the first record for the Indian Ocean.
