Neopetrosia sulcata Santos, Sandes, Cabral & Pinheiro, 2016

Holotype (not examined). Brazil, Rio Grande do Norte State, UFPEPOR 17, Potiguar Basin (4.62547º S, 36.76686º W), 70–101 m depth, leg. Petrobras, 2003.5.4.

Diagnosis. Irregularly cylindrical fragments. Surface punctiform or furrowed, rugose to the touch, with scattered circular oscules (1.5–10 mm diam.), always flush with the surface. Consistency hard, slightly brittle. Ectosome formed by tangential multispicular tracts (50–250 μm diam.), with rounded meshes (150–300 μm diam.), and the apical brushes of oxeas from longitudinal choanosomal spicule tracts. Choanosomal skeleton isotropic, with a superimposed anisotropic orientation of multispicular tracts and single spicules strewn in confusion. Oxeas smooth, relatively robust, usually curved, with fairly high percentage of variations at the ends (mucronate, stepped, hastate, asymmetrical, or blunt), 119–193 x 2.8– 9.6 μm [adapted from Santos et al. 2016].

Description. Refer to Santos et al. (2016).

Distribution. Tropical Atlantic. Brazil: Maranhão State ( Campos et al. 2005, as N. proxima ); Potiguar Basin, Rio Grande do Norte State ( Santos et al. 2016).
