Description

Colony unilaminar, encrusting, white; frontal wall smooth, only moderately inflated, completely covered with large pores, each occluded by a finely cribriform plate with triradial suture lines. Orifice D-shaped, broader than long, proximal margin straight, oral spines lacking. Ascopore ringed by a narrow rim; opening irregular, elliptical, or lunate in outline, the margin irregularly denticulate; separated from orifice by about length of orifice. Ovicell smooth, sunken in frontal wall of distal zooid, flattened, with chevron-shaped transverse ridge with small umbo at apex, and with semicircle of pores just inside the periphery.

Distribution

Mascarene Islands, Indian Ocean; Great Barrier Reef (for references, see synonymies). This is the first record for the Hawaiian Islands.
