Genus Cinachyrella Wilson 1925

Definition. Tetillidae usually with hemispherical porocalices (except in some stalked species), without spiculous cortical specialization ( Carella et al. 2016).

Diagnosis. Globular sponges with a hispid-bristly surface and numerous scattered porocalices; oscules inconspicuous. Skeleton radiate, consisting of bundles of oxeas issuing from the centre and spiralling to the surface. No cortical specialization. Megascleres are protriaenes, anatriaenes, occasionally plagiotriaenes, and dominant large oxeas; strongyles present in one species. Microscleres are sigmaspires (occasionally lacking) finely spined oxeas and/or raphides (amended from van Soest & Rützler 2002).
