Description Colony unilaminar, encrusting, light tan to off-white in colour. Frontal wall finely tuberculate, imperforate, with small, scarcely evident marginal pores. Primary orifice ( Figure 13G ) constricted laterally by obliquely triangular condylar processes; proximal margin straight. Oral spines lacking. Peristome proximal to orifice slightly developed as a thick, crescent-shaped ridge with a slight umbo in midline. A pair of avicularia lies lateral to orifice, both pointing proximally with long-setose mandibles; zooids with numerous long, spinous processes ( Figure 13H ) around zooidal margin. Ovicell ( Figure 13G ) raised, globose, smooth, slightly ridged in midline, with a double row of small pores in a crescent near distal end. Distribution Putatively circumtropical; Brazil , Caribbean, Mauritius , Vanuatu , and western Indian Ocean ( Tilbrook et al. 2001 ). This is the first record for the Hawaiian Islands.
