Spongilla corallioides Bowerbank 1863: 460, Bonetto & Ezcurra de Drago 1969: 352, Ezcurra de Drago & Bonetto 1969: 365. For other synonyms, see Muricy et al.(2011).
Material studied.UFPEPOR1300 ( in part), São Francisco River (II), Santa Maria da Boa Vista, Pernambuco, Brazil, 08°48'31.5"S 39°49'59.5"W, coll. L.R.C. Lima, 07.x.2011. FIGURE 4. Uruguaya corallioides: (a) megasclere strongyle; (b) megasclere oxea; (c) gemmuloscleres; (d) detail of gemmuloscleres surface. Scale bars: a, b, c—50µm, d—5µm. General morphology.Encrusting sponge measuring 1cmin diameter. Megascleres exclusively stout strongyles straight to slightly curved (201–264/15–24µm), smooth, rarely slender oxeas ( Fig. 4a,b). Microscleres absent. Gemmuloscleres are granulated strongyles (45–96/12–15µm), short, stout ( Fig. 4c,d). Gemmules are hemispherical, around 470µm in diameter, and gemmuloscleres are embedded tangentially.
Distribution and ecological notes.Specimens were found at rocky substrate in running waters: Brazil( Muricy et al.2011); Argentina, Paraguay, Uruguayand Venezuela( Bowerbank, 1863, Hinde 1888, Bonetto & Ezcurra 1964, Bonetto & Ezcurra de Drago 1969, Volkmer-Ribeiro & Pauls 2000).
Remarks. Uruguayais a monotypic genus with a restricted geographic range in the Neotropical Region. Uruguaya corallioideshas a wide distribution in South America. Furthermore, Brazilhas the most number of records for this species, mainly in north and south regions. Prior to the present study, however, it was unknown from northeast region.
