From cancelli lat. – latticed, and Entactinia.
One spherical latticed shell, constructed by a meshwork of short bars. Inner skeleton represented by an 8-rayed spicule, all eight rays originating from a central point. Eight main more robust spines develop from rays of the internal spicule.
The described genus differs from Polyentactinia Foreman (Foreman 1963, p. 281) in having a single internal spicule (without central bar) and the presence of only rod-like spines, and from Magnisphaera Won (Won 1997, p. 366) by one latticed shell and an internal spicule.
