Color
- Small juveniles dark brown with two bluish white lines, 1 midlateral and 1 on lower sides; Larger juveniles lose lower line, and lateral line becomes yellow.
- Females yellowish brown on body, grading to yellowish or greenish brown posteriorly with blue line along centre of each scale row; Head progressively more yellow or green anteriorly, lips bright yellow; Blue lines on head thicker and more irregular anteriorly, ending in one that encircles base of lips; Caudal fin with bright blue rear margin, broader at corners.
- Males dark olive, suffused with yellow or orange anteriorly on head, and bright blue longitudinal lines on body following scale rows; Broad pale yellow bar beneath and extending above pectoral fin; Blue lines on head more irregular and thicker anteriorly, ending in one around lips and continuing as broad irregular band ventrally on head; Fins dull orange-red with irregular blue lines basally, narrow blue margin and black submarginal line; Pectoral fins with bright yellow rays.
Etymology
Labrichthys: from Latin, Labrum = lip + from Greek, ichtys = fish.
unilineatus: from Latin prefix, uni- = one + from Latin, lineatus = line. Referring to single mid-lateral white stripe on juveniles.
