Without small rudimentary bulbs or secondary tentacles.All marginal bulbs without either lateral extensions or keel, excretory papillae present. Lateral and marginal cirri absent. Manubrium up to 1/2 umbrella width, broad and flat, not extending to velum, not connected to radial canals by mesenteries. Mouth simple, circular, without lips; gastric peduncle absent. Statocysts closed, numerous. Without ocelli. When mature, gonads extending along distal portion of radial canals, but not reaching peripheral canal.

The present material lacked marginal bulbs (as Bouillon 1984: 25), but is clearly recognisable by the small number of marginal tentacles and large number of radial canals.
