Colony encrusting, unilamellar, forming light-brown patches loosely attached to substratum. Frontal shield convex, evenly perforated by large pseudopores. Orifice rounded, slightly longer than wide, with a pair of well-developed, pointed, down-curved condyles and a relatively tall, narrow lyrula, both gutter-shaped, formed by folding of lamellar proximal edge of orifice. Anter of non-ovicellate orifices edged by low, crescentic blade recumbent on border with distally adjacent autozooid. Oral spines lacking. Suboral tall, antler-like mucro basically composed of bulging collar encircling proximal half of orifice from which is produced a medioproximal, vertically raised, compressed umbo bearing tubular processes: one vertical digitate process associated with a pair of longer, arched, lateral branches directed distally, and up to 3 digitate processes raised from trunk or lateral branches. Avicularian apparatus including 2

of adventitious avicularia: 1) at tip of tubular processes of umbo, several constant small, oval avicularia; 2) at distal corners of peristomial collar an infrequent large spatulate avicularium, frontally curved, borne by suboral mucro on which it replaces a lateral ramification, with rostrum upwardly directed, rounded and bulbous, denticulate distally. Both small oval and large spatulate avicularia have a complete crossbar. Ooecium hyperstomial, large, globular; ectooecium finely granular and punctuated by tiny pseudopores.
