Description[]
The coralite is simple and square shaped. Growth segments are clearly visible. The calyx is deep with weak septa, but some are thicker and more distinguished than others. Four "lids" called opercula create a pyramid over the calyx that could be opened in life. These lids are triangular with distinct lingual and labial ornamentation. Muscle scars and a stolon tube is found on the inside of each operculum. One of the lids is slightly larger than the others and it's the only one that is pressant in related genera such as . The corals internal Tabulae is very well developed much like other members of .[3]
