Diagnosis

Siphonophorae with an apical pneumatophore and beneath it, a series of nectophores (swimming bells), except in the genus Athorybia which lacks nectophores, forming the nectosome. Two budding zones present in most species, one under the pneumatophore giving rise to the nectophores and the other at the basal end of the nectosome giving rise to the cormidia that form the siphosome. Cormidia with bracts, palpons, gastrozooids and gonophores.
