in diameter. Autozooids at growing margin subhexagonal, with the angles rounded distally and proximally, and acute laterally; the overall shape less angular in older autozooids with heterozooids; arranged regularly in quincunx. Umbonuloid frontal shield not very convex, more or less smooth, with 5–7 conspicuous areolar pores along each margin. Primary orifice deep-set, proximal rim bearing 9–10 minute peg-like teeth along the proximal rim as seen from interior view. Oral spines usually 3, sometimes 4, on the distal rim of marginal zooids, proximal of which is a peristome that surrounds the rest of the orifice; middle part of peristome forming a bridge, creating a relatively large pseudospiramen, at the bottom of which the almost-concealed, minutely toothed border is just visible proximally; proximal margin of peristomial rim high, somewhat spout-like, sloping steeply to frontal shield. Oral spine bases mostly completely concealed in older or ovicellate zooids, although sometimes one can be seen adjacent to an avicularian rostrum projecting from a neighboring zooid. Avicularia paired or single, each budded from an areolar pore at widest part of zooid, the acute rostrum directed more or less laterally or slightly obliquely proximolaterally, the palatal foramen and avicularian opesia relatively large, separated by a complete crossbar. Ooecium recumbent on distal zooid, occupying much of its frontal shield, convex, smooth, subumbonate, forming a low arcuate rim around the distal margin of the maternal orifice, opening above secondary orifice. A pair of basal pore-chambers present in distal half of each zooid, with 1–2 mid-distally. Ancestrula not seen.
