Diagnosis Hydroids sessile, hydrorhiza fromed by creeping naked stolons, epizooic on tubes sabellid polychaetes; hydranths polymorphic; gastrozooid with rounded hypostome separated from the body by a constriction and with large cluster of nematocysts that is somewhat shifted to one side, two filiform tentacles arising below hypostomial constriction, opposite to nematocyst cluster, thus giving bilateral symmetry; gonozooid and dactylozooid without tentacles, mouthless and smaller than gastrozooid; medusa buds very close to gonozooidal tip. Medusa mostly hemispherical; manubrium with four to six or more radial gastric lobes extending along proximal portions of radial canals; gonads surrounding manubrium and extending on gastric lobes; radial canals branched, obliterated canals sometimes present; usually no circular canal but a circular gastrodermal ring; numerous exumbrellar nematocyst clusters or bands alternating with tentacles; marginal tentacles hollow, with swollen hollow base connected to the lumen of radial canals. Cnidome with or without desmonemes.  [details]
