General morphology. Encrusting sponge, fleshy, globular shaped ranging 3–10cm in diameter. Consistency of live sponge moderately soft, surface hispid. Caramel colour ( Fig. 9View FIGURE 9 a). Megascleres straight to slightly curved oxeas (276– 456 / 6–15 µm), sparsely microspined ( Fig. 9View FIGURE 9 b). Microscleres sharply pointed oxeas (63–102 / 3–4 µm), from curved to straight entirely spined with microspines ( Fig. 9View FIGURE 9 c). Gemmuloscleres birotules (51–87 µm/ 4–6 µm), bearing tapered spines on shaft, cut rotules (12–21 µm) microspined ( Fig. 9View FIGURE 9 d). Gemmules are hemispherical averaging 540 µm, abundant often at basal portion and scattered in the sponge body. Gemmular theca with welldeveloped pneumatic layer of spongin chambers and gemmuloscleres radially embedded ( Fig. 9View FIGURE 9 e,f).

Distribution and ecological notes. Brazil: ( Muricy et al. 2011); Argentina ( Bonetto & Ezcurra 1964, Ezcurra de Drago 1993). Specimens were found in ponds on artificial substrate in standing waters with Chironomidae  larvae ( Diptera  ) as symbionts. This species is widespread in all Brazilian regions.
