Description

Live sponge branching in shape, with prominent oscula organized in a row in the upper side ( Fig. 8A View Fig ). Color is light violet with visible whitish lines ( Fig. 8A View Fig ). The dried specimen is microhispid and spiny in the upper surface, close to the oscula, smoother in the basal part. The consistence is tough and incompressible.

SKELETON. Ectosome formed by a reticulation of unispicular primary fibers, 25–45 µm in section, and secondary unispicular fibers, 10–15 µm ( Fig. 8B View Fig ); the meshes are quadrangular and quite regular ( Fig. 8 View Fig B–C), 230–270× 250–350 µm. Choanosome formed by a regular reticulation of multispicular fibers, 45–65 µm in section, linked by secondary spongin fibers ( Fig. 8 View Fig D–E). These are cored by single oxeas (monospicular) and are 25–35 µm in section ( Fig. 8D View Fig ). The rounded meshes formed are 180– 275 µm wide.

SPICULES. Slightly curved oxeas with acerate tips ( Fig. 8F View Fig ), 77.5–(87, 6.3)– 97.5 µm × 1.25–(3.76, 1.1)– 5 µm.

Remarks

The morphology, skeleton, and spicule size, as well as the shape of the examined specimen fit those of the original description from North Kenya Banks. Moreover, the prominent oscula organized in a row on the upper side and the multispicular primary fibers of the choanosome are peculiar characteristics. The examination of the holotype ( Callyspongia subtilis Pulitzer-Finali, 1993   ) confirms the identification.

Callyspongia subtilis Pulitzer-Finali, 1993   was a junior homonymy recently removed by Van Soest & Hooper (2020) who renamed the species in honor of Gustavo Pulitzer-Finali.

This is the first record of the species since its original description from Kenya.
