. Colonies minute, domed, with mamillate calcification, that forms a raised mound adapically and covers the antapical surface. Primary orifice obscure, with a rounded sinus. Peristomes elongated; tubular and marginally prominent. Root pores adapical, rare, rounded. Lateral peristomial avicularia paired, very small, rostrum rounded. Ovicells developed on zooids of the second and third whorls, symmetrical, globular, very well calcified, opening into the peristome through a foramen. Ectooecium narrow, marginal; entooecium with frontal and marginal pores. Antapical surface granular and mamillate.

Zooids apparently develop an elongated peristome, with a foramen on its adapical surface. This is in contact with an adapical pore (
