Colony encrusting, multiserial. Zooids large, hexagonal. Frontal shield flattened, covered with fine pointed tubercles. Marginal areolae small, deeply submerged. Interareolar ridges short, mostly not reaching cystid of suboral avicularium. Umbonuloid component extensive. Primary orifice proportionally large, occupying over 30% of zooid length, roughly quadrangular, with large lateral condyles. No oral spines. Secondary orifice identical in form to primary orifice, cormidial. Suboral avicularian cystid small, slightly elevated, narrow, forming crescentic lip around proximolateral edge of primary orifice. Rostrum semioval, blunt. Crossbar complete, thickened in the middle or with very small ligula. Multiple adventitious frontal avicularia, 2–5 per zooid, of equal size and form, situated along lateral margins. Ovicells hyperstomial, rapidly subimmersed by peripheral secondary calcification. Ectooecium smooth, with scattered pseudopores. 3‒5 pore chambers in distolateral wall and two multiporous septula in transverse walls. Basal wall of zooids fully calcified, with protuberances of irregular form.
