Diagnosis

Lelapiidae with syconoid or sylleibid organisation. The cortex is composed of tangential triactines, and occasionally has an external layer of small diactines perpendicular to the surface. The proximal layer of the choanoskeleton is composed of subatrial triactines and/or tetractines, whose unpaired actines are associated with modified triactines that have very reduced paired actines. These modified triactines are either isolated or form short bundles joined by an organic material, and support the external part of the choanosome.
