Material examined: 3 medusae; France, Roscoff, 48.73°N 04.00°E, 0-20 m depth, collection date April 1998; DNA isolate N119; 16S sequence KX355404 View Materials , COI MF000485 View Materials , 18 View Materials S FJ550521 View Materials , 28S FJ550374 View Materials GoogleMaps   .

Diagnosis: Umbrella diameter 4-7 mm, umbrella usually somewhat flatter than a hemisphere, lateral jelly rather thin, apical jelly somewhat thickened, no gastric peduncle. Velum width 1/3 to 1/4 of radius. Manubrium short, cruciform cross-section, base not much larger than oral end, mouth simple, four perradial, slightly recurved lips. Radial canals 4, narrow, straight. Gonads oval, somewhat more elongate in females, situated near the ends of the radial canals, in younger animals more towards middle. Marginal tentacles typically 16, range in adults 11-24, with basal bulbs, 5-7 cirri between adjacent tentacles, coiling spirally. Typically 8 large, adradial statocysts (range 8-11), each with 5-7 concretions in a u-like arrangement. Colours: manubrium greenish, pink, or ochreous yellow.

Polyp stage tiny, of “ Cuspidella   ” type, see Cornelius (1995).

Distribution: British Isles, Brittany, Mediterranean, New Zealand. Type locality: North Sea.
