Diagnosis

Heteropiidae with short radial tubes supported by a skeleton composed of a proximal row of subatrial triactines and distal pseudosagittal triactines, with occasional tube spicules. The paired actines of proximal subatrial spicules are adjacent to the atrial skeleton, while the unpaired actine is in the wall of the radial tube. The shorter paired actine and the unpaired actine of the distal pseudosagittal spicules support the distal cones, while the longer paired actine is inside the wall of the radial tube. Syconoid type of organisation.
