Hercosestria is an extinct genus of brachiopods from the Lower and Middle Permian. [1] They were important reef-forming organisms because of their conical shapes, attaching spines, and gregarious habits. [2] It is related to Richthofenia. [3] Species of the genus have been found in Texas (H. cribrosa and H. laevis) and Guatemala (H. notialis).
