Colony encrusting, multiserial, partly forming small free-growing frills. Zooids large, oblong-hexagonal. Frontal shield moderately convex, very finely granular. Interareolar ridges reaching avicularian cystid in distal part of zooid. Umbonuloid component extensive. Primary orifice submerged, broadly circular, with very broad median lyrula-like prominence. No condyles. Secondary orifice transversely oval, cormidial; proximolateral curvature incorporating large mucro with two thin-walled symmetrical lateral lappets. 1‒2 pairs of long, tubular, basally articulated oral spines around distal curvature of orifice. Suboral aviculiferous mucro very tall, conical to bulbous, finely granular, bearing 3–5 spirally arranged avicularia decreasing in size towards apex. Basalmost main avicularium budding 2–4 smaller avicularia. No adventitious avicularia. Ovicells hyperstomial. Ectooecium smooth, with numerous scattered pseudopores, mostly with no secondary calcification. 4–5 pore chambers in distolateral wall and two multiporous septula in transverse walls. Basal surface of zooids fully calcified, with numerous tubular protuberances.
