Lithoprimnoa Grube, 1861: 174–175 .

Diagnosis (from Cairns & Bayer, 2009, edits in bold): Colonies dichotomously branched and usually bushy. Calyces closely spaced and randomly arranged on all branch surfaces, the appressed calyces facing downwards. Well-developed operculum present, opercular scales keeled on inner surface. Polyps large and fleshy, each polyp protected by two rows of three or more large abaxial scales, sometimes arranged in an irregular manner, two short inner lateral rows of two or three smaller scales (including the marginals), and two even shorter rows of two (including the marginals) adaxial scales, resulting in six longitudinal rows, but four of them composed of few variable-sized scales; adaxial side of body-wall predominantly bare. There is also a crown of eight large, concave marginals, the adaxial marginals usually smaller than other marginals. Coenenchymal scales arranged in one layer. Tentacular rods often present.

Type species: Gorgonia lepadifera Linneaus, 1767 (= Gorgonia resedaeformis Gunnerus, 1763 ), by monotypy. Type not found.
