Material studied. MNRJ 15436, São Francisco River (I), Ilha de Assunção, Cabrobó, Pernambuco, Brazil, 08° 32 '25,5"S 39 ° 26 '41,5"W, coll. J. A Siqueira-Filho, 30.vii. 2011.

General morphology. Encrusting sponge measuring 10cm in diameter and 0.5cm in thickness. Consistency of live sponges very hard and fragile, conspicuous oscula. Colour grey. Spicules. Megascleres strongyles curved (141–168 / 30–45 µm), small, robust, smooth ( Fig. 11View FIGURE 11 a). Microscleres absent. Gemmuloscleres tiny birotules (15 µm) with smooth stout shaft (6–9 µm), equal rotules (15 µm) with uncut/entire margins and a conical projection at the middle ( Fig. 11View FIGURE 11 b). Gemmules are minute hemispherical averaging 360 µm diameter, rare, and scattered in the sponge body ( Fig. 11View FIGURE 11 c,d).

Distribution and ecological notes. Brazil ( Muricy et al. 2011). Argentina, Paraguay, Uruguay and Panama ( Hinde 1888, Bonetto & Ezcurra de Drago 1962, Penney & Racek 1968, Volkmer-Ribeiro & De Rosa-Barbosa 1985). Specimens were commonly found on rocky substrate in running waters.

Remarks. Although Tubella repens  has a widespread distribution in the Neotropical Region, there are still some issues on taxonomic features described in most records of the species. Many Brazilian records describe this species with strongyles, oxeas or both. This misidentification sometimes is related to specimens with other freshwater epibiont sponges commonly found with this species ( Hinde 1888, Volkmer-Ribeiro 1969, Volkmer- Ribeiro & De Rosa-Barbosa 1985, Batista et al. 2003, Batista et. al. 2007, Volkmer-Ribeiro et al. 2010, Volkmer- Ribeiro & Parolin et al. 2010). Thus, most recorded specimens should be reexamined to determine whether this species is really widely distributed in South and Central America.
