Specimens.

MZB. Asc. 00006

Habitat.

Shaded side of dead coral branches in reef flat.

Remarks.

Colonies were oval cushions and entirely green due to Prochloron cells distributed within the common cloacal cavities. A blue ring of structural color encircled each branchial siphon. Retractor muscle emerged from halfway along esophageal neck of a zooid. On each of the right and left halves of the branchial sac, there were five stigmata in the first (top), second, and third stigmatal rows and four stigmata in the fourth row (bottom). Here, we describe the pattern of stigma number as 5 –5–5– 4. This record is the first of this species from outside of the Taiwan–Ryukyu area.
