Family Trypostegidae GORDON, TILBROOK et WINSTON, 2005 View in CoL Genus Trypostega LEVINSEN, 1909 View in CoL

Colony encrusting. Frontal wall perforated by many simple pores. Aperture keyhole-shaped (‘cleithridiate’) with sinus and prominent condyles. No oral spines. Heterozooecia with small orifices present. Ovicell hyperstomial, very large with a completely perforated frontal wall.

R e m a r k s: According to Tilbrook (2006) Trypostega lack oral spines, but the very similar genus Hippothoa oppositely has developed many spines around aperture.
