This identification is somewhat tentative. It has some resemblance to Eviota melasma in Greenfield & Winterbottom (2016), but is not an exact match. It is also similar to Eviota smaragdus, E. sp. 4 and E. sp. 7 on these pages. Our specimens may all turn out to be variations of one species. The photo is by Stan Jazwinski.
The individual below was on the seaward reef.
