Parmula cristata Weltner, 1895: 143  ; Penney 1960: 55. For other synonyms see Muricy et al. (2011).

Material studied. UFPEPOR 1117 (in part), 1118 (in part), São Francisco River (III), Petrolândia, Pernambuco, Brazil, 09°08' 37.1 "S 38 ° 17 ' 48.9 "W, coll. E.L.R. Lima, 19.v. 2010. UFPEPOR 1300, 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.

General morphology. Encrusting sponge measuring 1cm de diameter, brown colour. Spicules. Megascleres slightly curved (372–468 / 35–48 µm), robust, smooth strongyles ( Fig. 2View FIGURE 2 a,b). Microscleres microspined straight, acanthoxeas (78–123 / 3–6 µm), middle spines (3–6 µm) tapered ( Fig. 2View FIGURE 2 c,d). Gemmules are hemispherical raging 384–540 µm in diameter ( Fig. 2View FIGURE 2 e). Gemmular theca made by thin layer consisting of spongin, where gemmuloscleres are embedded tangentially ( Fig. 2View FIGURE 2 e).

Distribution and ecological notes. Brazil ( Muricy et al. 2011); Venezuela ( Volkmer-Ribeiro & Pauls 2000). Specimens were found on rocky substrate in running waters along with Uruguaya corallioides ( Bowerbank, 1863)  , Corvospongilla seckti Bonetto & Ezcurra  de Drago, 1966 and Oncosclera navicella ( Carter, 1881)  .
