Diagnosis
Medusa with very short manubrium on large gastric peduncle; mouth with 8-30 sinuous or crenulated folds; eight or more radial canals, simple, ramified, or in clusters of four; up to 64 marginal tentacles, laterally compressed; no marginal cirri, but in intertentacular space filiform, tentaculiform structures devoid of marginal bulbs, not in contact with circular canal; gonads usually on proximal parts of radial canals; numerous (up to 800) adaxial ocelli; without statocysts, without cordyli, without excretory pores or papillae.
Hydroid phase unknown. [details]
Nomenclature
The grammatical root for the formation of the family name based on the genus name Orchistoma is "stomat-", not "stoma-", for it is derived from "stomatos", the genitive form of the Greek word "stoma" (compare Genus Myzostoma Family Myzostomatidae). The correct family name is thus Orchistomatidae and not as first proposed Orchistomidae. [details]
