General morphology. Encrusting thin sponges. Colour beige and green. Consistency of live sponges fragile to moderately soft ( Fig. 12View FIGURE 12 a). Spicules. Megascleres predominantly straight to slightly curved, robust, smooth oxeas (150–288 / 6–12 Μm) ( Fig. 12View FIGURE 12 b). Microscleres absent. Gemmules are minute hemispherical averaging 260 Μm in diameter, scattered in the sponge body ( Fig. 12View FIGURE 12 c,d). Gemmuloscleres birotules (9–11 Μm), slender shaft (3 Μm), unequal rotules (6–15 Μm), inner rotules are circular and outer rotules corolla shaped ( Fig. 12View FIGURE 12 e). Gemmular theca made by thin layer consisting of spongin, where gemmuloscleres are embedded radially.

Distribution and ecological notes. Brazil ( Muricy et al. 2011). Argentina, Costa Rica (Ezcurra de Drago 1993, Volkmer-Ribeiro & Machado 2009). Specimens were collected in lentic waters from concrete substrate. This species is widespread in the Neotropical Region and commonly found in all Brazilian regions.
