Comparison The genus is very close of Complexastrea but meandroid. [details]
Description Massive meandroid corallum with short valleys. Septa of valleys not always present. No ambulacrum, just sometimes a small sulcus on the collines. Poorly elevated tholiform collines. No holotheca observed. Intracalicinal increase producing sinuous valleys with only one center in the width of the valley. New corallites occur also between valleys. Radial elements are compact free bicuneiform or attenuated, often curved, sometimes straight, confluent or not confluent on the collines. Distal edge with regular teeth (not well preserved on the lectotype); some trifid teeth typical for Montlivaltids observed at distal inner edge, lateral faces with acute granules or carinae(?), no pali. Montlivaltid microstructure. Hexameral symmetry cannot be deciphered, bilateral symmetry visible with curvature of septa. Endotheca made of dissepiments, columella absent, axial zone with a small fossa, synapticulae absent. Parathecal wall between valleys. [details]
