Colony encrusting. Autozooids are hexagonal or sometimes polygonal, concave, separated by marginal rim and distinct sutures. Membraneous frontal membrane translucent, light orange-brown, covering the sparsely granular cryptocystal frontal space, opesia small, an elongate D-shape, in distal half of zooid, surrounded by frontal cryptocyst. Operculum dark brown-orange in colour, smaller than opesia, lacking any discernible marginal sclerite. Avicularia and autozooids are narrower and apparently torqued towards its sibling autozooid. Cryptocyst granular,concave, opesia elongate oval, distally located, proximal border denticulate, smooth distally, a pair of condyles developed approximately two-thirds along each lateral wall; distal end of avicularium drawn to a point, turned towards its sibling zooid and channeled to accept the mandibular rachis; mandible long; rachis light chocolate brown in colour, hooked at its tip, translucent light orange-brown baldes; fertile zooids similar to in size to autozooids but with dimorphic opesia. Opesial shape; Avicularian shape with its pointed distal end and turned towards its sibling zooid.
