Colony encrusting, autozooids large, elongated. Frontal shield moderately convex, evenly perforated by large circular pseudopores. Primary orifice deep, partly concealed by trifoliate secondary orifice. Peristome cormidial, distal part formed by proximal edge of daughter zooid, separated by deep pseudosinuses from proximal part with strongly projecting rim angled over orifice at 60–70° to frontal plane. Paired heterozooids at lateral-suboral corners in place of avicularia.
