Arturia hirsuta is a species of calcareous sponge from South Africa.

Cormus composed of large, irregular and loosely anastomosed tubes.

Water-collecting tubes converge to form conical projections with an osculum.

The surface of the tubes is hispid because of the presence of diactines and trichoxea.

The skeleton comprises equiangular and equiradiate triactines and very few tetractines.
