Suboral sinus U-shaped, moderately shallow, narrow, flanked by straight orificial margin and broad, semicircular condyles. Oral denticles indistinct. Oral spines lacking. Zooids with suboral avicularium and single frontal avicularium. Suboral avicularium relatively broad; uncinus scarcely evident. Frontal avicularia relatively short, broad; weakly diamond shaped or semicircular proximally; scarcely decurved, with triangular mandibular portion lacking setiform end; paired crossbar elements V-shaped. Ooecium with transversely oval endooecial panel in peristome; labellum present but not markedly broad. Cylindrical projections around secondary orifice in older parts of colony.

Frontal wall at margin smooth, convex, imperforate, with 7–10 small, circular areolae along each lateral margin; with thickening frontal calcification, areolar openings become larger and fewer, five or six along each lateral margin. Primary orifice with anter D-shaped or nearly circular; median sinus variable, ranging from narrowly U-shaped to more broadly rounded-V-shaped, flanked on each side by small shelf, with rounded condyle filling angle between shelf and lateral orifical margin; condyles not directed distally.

Rostrum directed laterally, with rostral plane also tilted slightly toward distal end of zooid; mandibular portion asymmetrical, forming right triangle, or symmetrical, forming short-equilateral triangle; opesial margin of mandibular portion irregular with one or two coarse, nodular denticles on each side. Hinge element on each side of rostrum narrowly V-shaped, apex pointing medially, with or without complete crossbar extending between opposing elements. Suboral avicularium occasionally larger, twice as long as orifice width, with rostral plane convex in frontal direction. Most zooids have single frontal avicularium located in proximal half of frontal shield, directed distolaterally, laterally, proximolaterally, or proximally; frontal avicularia similar in size and shape to suboral avicularia; ratio of average rostrum length to rostrum width = 1.9; proximal end of rostrum usually acute (rostrum diamond-shaped), but sometimes rounded as in suboral avicularia; mandibular portion usually symmetrical and long-triangular, sometimes asymmetrical and comprising right triangle. Opesial margin of mandibular portion irregular, with up to six coarse, rounded denticles on each side. Rostrum slightly decurved at end, indicating mandible is probably hooked distally.</paragraph>
