Diagnosis 
Very large hydromedusa with wide, circular manubrium; usually no gastric peduncle; numerous simple or branched radial canals; gonads on radial canals, separated from manubrium; marginal tentacles hollow; usually with excretory pores or papillae on bulbs; no marginal or lateral cirri; statocysts closed; no ocelli.
Hydroid colony stolonal or sparingly branched; hydrotheca delicate, tubular, elongated, radially symmetrical, operculum a continuation of hydrothecal wall, composed of several long, triangular flaps, not delimited by crease-line; in older colonies operculum generally lost and hydrotheca reduced to a perisarcal collar; hydranth with intertentacular web, tentacles amphicoronate, moniliform-like when completely extended; gonotheca large, pedicellate, cylindrical, giving rise to one or two medusae.  [details]
