Type species.

Isaurus tuberculatus  Gray, 1828, by monotypy.

Gender.

Masculine.

Diagnosis.

Zooxanthellate, absence of mineral incrustations in the column/coenenchyme (excluding superficial surface attachments) brachycnemic zoantharians with recumbent (non-erect) polyps. Often have tubercules (raised bumps = endodermal invagination) on the outer surface of polyps, except in Isaurus maculatus  Muirhead & Ryland, 1985, which has a smooth polyp surface.

Remarks.

Specimens examined with an orthogonally-reticulate mesogleal sphincter muscle ( Swain et al. 2015).

Ryland and Lancaster (2003) recognised only three valid species in this genus, although 22 species have been described in or assigned to this genus.
