The pairs of caveal ribs are paired on the dorsal rod of the a-rod; The patagial tissue is present on one lateral side of the i-rod. A single row of arches (or by-spines) connect the primary spines, forming a simple cortical shell.”( Wang et al. 2010: 48).

This genus differs from Protoceratoikiscum in that it has a framework composed of 6 rods connecting to a median bar. Ceratoikisum has 3 rods (a, b, intersector) that cross to form a triangle. It differs from Protoceratoikiscum in that it possesses row of arches that connect the primary rods to form a subcircular shell, and the rods join in an eccentric position in Gansuceratoikiscum .
