Description

Colony unilaminar, encrusting; ectocyst a rich chocolate to sienna colour; zooids large. Frontal wall smoothly tuberculate, covered with minute pores except for area proximal to peristome. Peristome well developed, same texture as frontal wall. Zooids often with a distomedially directed frontal avicularium appressed to peristome on one side, mandible equilateral, acute. Primary orifice ( Figure 11C View Figure 11 ) nearly circular, with small, rounded condyles separated by a notch from concave proximal orificial margin. Oral spines lacking. Ovicell ( Figure 11B View Figure 11 ) globose, hyperstomial, broader than long, same texture as frontal wall, uniformly perforated by minute pores; secondary orifice of ovicellate zooids roundtriangular in outline.

Remarks

Zooid size is larger than reported for other populations, but otherwise the morphology of Hawaiian specimens is indistinguishable from that of specimens from other populations (e.g. Ryland and Hayward 1992; Tilbrook et al. 2001).

Distribution

Widely distributed in Indo-West Pacific, from Red Sea to Tahiti and Hawaii ( Tilbrook et al. 2001).
