Diagnosis A superfamily of Comatulidina with centrodorsal conical to discoidal; aboral pole in adults cirrus-free or with traces of sockets, commonly rugose. Most genera with 5 pits arranged radially around apex. Centrodorsal cavity 20-30% of centrodorsal diameter, always surrounded by, or exceptionally fused with, 5 radial pits housing coelomic extensions outside chambered organ and nerve capsule of centrodorsal cavity. Cirrus sockets generally large, with more or less distinct articular tubercles. Sockets in 10-20 columns. Rod-shaped basals commonly exposed interradially, with or without subradial cleft. Radials with low exposed surface or concealed; distal margin may be concave, reaching edge of centrodorsal only interradially. Radial articular facet generally rather low and wide. Muscle fossae distinct, similar in size to interarticular ligament fossae or higher. Radial cavity narrow to wide and funnel-shaped. Arms 10, divided at primibrachial 2 (H. Hess, 2010, in press).  [details]
