Suboral sinus U-shaped, moderately shallow, narrow. 20–23 oral denticles. Oral spines lacking. Zooids with suboral avicularium and single frontal avicularium. Suboral avicularium with mandibular part of rostrum right-angled, and with proximal uncinus. Rostrum of frontal avicularia diamond shaped, decurved, with narrow, distal channel for setiform mandible; avicularian crossbar simple. Ooecium with large endooecial panel vertical in peristome, flat, with marginal pustulation; labellum wide. Scattered surface nodules in older parts of colony.

Frontal wall initially convex, smooth, imperforate, with six or seven small, irregular areolae along each lateral margin. Orifice with anter broader than long; overall (including sinus) about as long as broad. Median sinus distinct, moderately wide and deep, U- or rounded-V-shaped, flanked by prominent, rounded condyles, bounded by small secondary condyles.

With age and increasing secondary calcification, zooidal boundaries obscured; frontal surface smooth, but irregular, with scattered coarse tubercles; secondary orifice with distinct, wide pseudosinus on one side or other, with up to five or six tuberculate prominences around proximal and lateral margins.</paragraph>
