Polyp: Colonies stolonal with hydrothecae on pedicels, which are smooth and annulated. Annulated stretch at proximal and apical parts of pedicel. Hydrothecae bell shaped, with rounded and symmetric cusps; embayments rounded. Diaphragm inconspicuous and thin in the basal section of the hydrotheca. Reproduction: Gonothecae ovoid, on short pedicel, distal end broadly truncate and wall with more or less distinct spiral ridge. Gonophores released as free medusae. Medusae with diameter up to 20 mm, hemispherical to slightly flatter, with fairly thin jelly; velum ca 1/6 bell radius. Stomach short, quadrate, with small base; no peduncle. Mouth with four short lips. Radial canals straight, usually 4 but individuals having up to twelve are not uncommon in some populations; ring canal narrow. Gonads elongate-oval, on distal 1/3 of radial canals. Marginal tentacles typically 32 but fewer in young medusae, smooth, hollow, with spherical bases. Marginal bulbs few, partially developed; no cirri. Marginal vesicles closed, each with one concretion, rarely two; 1-3 vesicles between adjacent tentacles. Coloration varied, marginal tentacle bases and stomach yellowish, yellow brown, reddish brown, greenish or purple; gonads yellowish. Ecology and Distribution: Circumglobal species. Known from Bocas del Toro from Crawl Cay and Bocatorito Bay. Similar taxa: Clytia gracilis.
