Family Cucumellidae Thandar & Arumugam, 2011

Diagnosis (from Thandar & Arumugam 2011, amended herein).

Dendrochirotid holothuroids with about 12 tentacles, digitate, unbranched. Calcareous ring simple, without posterior bifurcation of the radial plates; test absent; body wall ossicles non-contiguous, comprising simple tables with mostly trilocular to multilocular smooth disc, with a solid or 3-pillared spire ending in 2–3 (sometimes 4), smooth or toothed processes.

Remarks. In the diagnosis of their new family, the authors state that the spire of the table ends in 2–3 smooth, diverging processes. Ludwig & Heding’s description of the tables is not clear and no tables could be found in the still extant holotype. However, in the current specimens it appears that C. triplex, the type species, has a spire ending in 3-, sometimes 4-toothed processes. The diagnosis is, therefore, here amended to include this feature.
