Longitudinal muscles of tentacles uniformly developed all round the tentacles. Oral disc wide. Actinopharynx long, with 2 very broad siphonoglyphs aborally prolonged. Mesenteries rather thin, more numerous distally than proximally. Not half of the mesenteries perfect. Retractors weak, forming no distinct pennons. Parietobasilar muscles distinct, forming a fold, basilar muscles well developed. The two first cycles of mesenteries sterile. Cnidom: spirocysts, basitrichs, microbasic p-mastigophores.
