Description

Colony unilaminar, encrusting. Gymnocyst scarcely evident; cryptocyst ( Figure 5A, B View Figure 5 ) very wide and shallowly sloping proximally, narrowing and steep distally, with coarse, rather irregularly arranged tubercles; opesia large, irregularly oval or subtriangular. Interzooidal avicularia small, on a raised cystid; some zooids have a kenozooidal papilla at proximal end, replacing or together with an avicularium. Ovicells lacking, but the raised, smooth distal zooidal margin in fertile zooids ( Figure 5B View Figure 5 ) may represent a vestigial ovicell. Spines lacking. Autozooid-sized vicarious avicularia can occur, but are absent in our specimen.

Remarks

Only one small, dead colony fragment was found, at Kapa’a.

Distribution

Circumtropical ( Tilbrook, 1998); not previously reported from the Hawaiian Islands.
