The anthiine fish Selenanthias myersi is described from three specimens from the South China Sea off Viet Nam taken by trawl in 110-200 m and one from Guam in 220 m. It is distinguished from the only other species of the genus, S. analis Tanaka from Japan and Taiwan, by having 22 instead of 19-21 lower-limb gill rakers, a narrower interorbital, and no large black spot posteriorly on the anal fin.
