Description 
Mature medusa 5-10 mm high, maximal bell diameter about the same as height, umbrella bell-shaped with flat top, jelly uniformly thin. Manubrium on a transparent, shallow peduncle, not encircled by blocks of vacuolated cells but vacuolated cells present along proximal parts of radial canals. Manubrium large, up to 2/3 of subumbrellar height, ovoid, manubrium base constricted, with funnel-shaped mouth region. Stomach and mouth region distinctly cruciform in cross-section. Radial canals where joining manubrium funnel-like dilated and composed of large, vacuolated cells, continued on manubrium as perradial ribs resembling four clasping claws. Mouth rim in folds, with four prominent perradial lips. Margin of mouth with a continuous row of spherical nematocyst clusters, these usually on a short pedicel. Gonads smooth, on interradial surface of stomach. Four quite broad radial canals, margins occasionally jagged, circular canal broad. Marginal tentacles 80-120, evenly tapering, gastrodermis chordoid. Origins of tentacles somewhat alternately displaced adaxially and abaxially (= in 2 rows). Each tentacle with a slight proximal swelling beginning shortly after origin. Adaxial ocelli near tentacle base. Nematocysts: microbasic euryteles, desmonemes. Colours: manubrium and gonads yellow, orange or orange brown, ocelli brown-red. Egg size about 0.27 mm.
Polyp stage forming erect, branched colonies, 1-10 cm, strongly polysiphonic, thinning out to monosiphonic. Proximal parts of monosiphonic side-branches and hydranth pedicels adnate to branch of origin. Hydranths at ends of side branches, tubular, 0.6-1 mm high, with rounded hypostome, up to 18 scattered filiform tentacles. Medusa buds at end of thin side-branches with proximal region adnate, spherical, 0.4-0.5 mm, in advanced stages with four broad radial canals, manubrium very short, with four interradial pads, four marginal bulbs, about 8 tentacles stubs. Nematocysts of polyps are microbasic euryteles and desmonemes.

Distribution 
The medusa occurs in coastal waters of tropical to warm temperate seas. It has been recorded from the Mediterranean, coasts of Senegal and Gambia, Canary Islands, Cape Verde, Azores, Portugal, West Indies, Japan, New Zealand, Tasman Sea, South China Sea, Red Sea; apparently it is absent from the eastern Pacific Ocean. The medusa occurs usually in depths of less than 200 m, but not at the surface. [details]

The medusa occurs in coastal waters of tropical to warm temperate seas. It has been recorded from the Mediterranean, coasts of Senegal and Gambia, Canary Islands, Cape Verde, Azores, Portugal, West Indies, Japan, New Zealand, Tasman Sea, South China Sea, Red Sea; apparently it is absent from the eastern Pacific Ocean. The medusa occurs usually in depths of less than 200 m, but not at the surface. [details]
