Type locality: Bijoutier Island , Amirantes, Seychelles, Indian Ocean .

Colour: This species can have several colours ( Fig. 26 View Figure 26 ). Some were mostly pink but white at the base (UFRJPOR 8925; Fig. 26A View Figure 26 ) or white with a pink sponge budding (UFRJPOR 8929) or even lemonyellow (UFRJPOR 8938; Fig. 26B View Figure 26 ), white but pink near the osculum (UFRJPOR 8942) or completely white (UFRJPOR 8943, 8948; Fig. 26C View Figure 26 ). They all become beige in ethanol ( Fig. 26D View Figure 26 ).

Morphology and anatomy: Sponge with a shape of vase with one single apical osculum surrounded by a crown of trichoxeas and with a delicate sphincter ( Fig. 26A–D View Figure 26 ). The crown is supported by T-shape triactines ( Fig. 27A View Figure 27 ). Frequently there are sponges budding from another and they keep connected to each other ( Fig. 26D View Figure 26 ). Surface smooth, covered by huge longitudinal diactines ( Fig. 27B–D View Figure 27 ). These diactines protrude through the surface near the osculum ( Fig. 27A View Figure 27 ). The surface is perforated by ostia surrounded by tiny curved triactines, giving a honeycomb appearance to it ( Fig. 27C, D View Figure 27 ). The aquiferous system is syconoid ( Fig. 27B View Figure 27 ). The cortical skeleton is composed of the giant longitudinal diactines and by the tiny triactines of the ostia ( Fig. 27C View Figure 27 ). Below, the articulated tubar skeleton is composed of triactines pointing their unpaired actine to the surface ( Fig. 27D, E View Figure 27 ). The subatrial skeleton has triactines and few tetractines and the atrial skeleton has only tetractines ( Fig. 27E View Figure 27 ). The atrium is hispid ( Fig. 27E, F View Figure 27 ).
