M a t e r i a l e x a m i n e d: U F R J P O R 8 9 3 9 (= 171109- PAE2 - TP15 ). Photos : TP6059–6060. Passe de l’Hermitage Reef, La Réunion, Indian Ocean, coll. T. Pérez, 9 November 2017, 18– 20 m depth .

Colour: Lemon-yellow alive and white after fixation ( Fig. 16A, B View Figure 16 ).

Morphology and anatomy: Sponge formed by several globose parts, each one with a single apical osculum surrounded by membrane ( Fig. 16A, B View Figure 16 ). Surface smooth and transparent. Canals can be seen below the surface. Although the atrium is reduced, it obviously receives a large number of exhalant canals. The aquiferous system is leuconoid ( Fig. 16C View Figure 16 ). The skeleton is composed of two size categories of cortical triactines ( Fig. 16D View Figure 16 ). The small triactines form the main part of the choanosomal skeleton, which has also rare small tetractines surrounding the canals. The atrial skeleton is composed of the small triactines and the rare tetractines.
