Description Small massive thamnasterioid corallum with large corallites. Epitheca absent or eroded. Costae subequal. Intracalicinal increase. Radial elements are compact anastomosing, subequal in thickness along the radial directions and subequal from one to another, straight or curved. Distal edge moniliform with regular teeth corresponding to heads of trabecules, inner edge not observed, lateral faces covered of menianae, pennular outline festooned (seen from above). Microstructure not known. Hexameral symmetry cannot be deciphered, bilateral symmetry due to curvature of septa. Abundant endotheca made of dissepiments. The axial zone of the holotype cannot be satisfactorily observed. Synapticulae probably present but it is difficult to distinguish from connecting pennulae or thick dissepiments without thin section properly oriented. Wall absent between corallites. [details]

Comparison It looks like a colonial Leptophyllia [details]Description Small massive thamnasterioid corallum with large corallites. Epitheca absent or eroded. Costae subequal. Intracalicinal increase.

Remark Of the nominal species cited for Tricycloseris, probably only the type species, known by only one specimen is a Tricycloseris. Gregory's "Tricycloseris" from India have perforated septa. [details]
