Rocha, Lívia, Moraes, Fernando, Salani, Sula & Hajdu, Eduardo, 2021, Taxonomy of Petrosiidae Van Soest, 1980 (Haplosclerida, Porifera) from Brazil, Zootaxa 5004 (2), pp. 251-287 : 252

Genera Neopetrosia de Laubenfels, 1949

Petrosiidae with finely hispid surface produced by fine brushes of oxeas issued from subectosomal tracts, and a compact choanosomal network combining rounded meshes with a superimposed anisotropic reticulation. Megascleres oxeas, mostly less than 200 µm long (modified from Desqueyroux-Faúndez & Valentine 2002).

Remarks. We chose to acknowledge that oxeas in Neopetrosia spp. are frequently over 200 µm long, after a series of new species had been added to the group possessing oxeas quite larger than this limit defined in the Systema Porifera (i.e. up to 300 µm; e.g. Van Soest et al. 2014; Zea et al. 2014; Vicente et al. 2019).
