A new labrid fish Terelabrus flavocephalus sp. nov., the third species of the genus, is described on the basis of a single specimen collected from the Republic of the Maldives. The new species is characterized by 46 scale rows in longitudinal series; 44 pored lateral-line scales; 13 gill rakers, including rudiments; main supratemporal sensory canal (STC) with 9 branches posteriorly; areas bounded by STC and postotic sensory canals (dorsal view) with embedded scales; least distance between anteroventral margin of orbit and maxilla 0.4 % of standard length; no red blotches superimposed on or extending onto midlateral red stripe; no yellow stripe on dorsal fin when fresh; a vivid yellow stripe extending from below the anterior margin of the orbit to preopercle and a vivid yellow blotch or band on the lower part of the opercle when fresh; a distinct black stripe from the center of the upper lip through the eye to opercular margin in preservation.
