Diagnosis Calycophorae which develop a temporary larval bract before the larval nectophore, the latter is retained in the polygastric stage as the anterior nectophore. All but one species develop a second (definitive) nectophore, the posterior one, which is usually considerably larger than the anterior one and does not possess a somatocyst. The nectophores are ridged and angular, the posterior one usually bearing serrated ridges and teeth. The hydroecium of the anterior nectophore is an enclosed tube opening basally.  [details]
