Other Notes
Smith-Vaniz & Emery (2013) elevated this species from the synonymy of Chromis flavicauda based on consistent color pattern differences and the extreme allopatry of their ranges implying lack of connectivity. A comprehensive molecular and morphometric study must be done to confirm this decision.
