Etymology: Meiacanthus: Greek, meion = less = lessen + Greek, akantha = thorn (Ref. 45335); luteus: Specific epithet means 'yellow', referring to the brilliant upper body coloration of the species.

Morphology | Morphometrics
soft rays: 16 - 18. Males with prolonged pelvic fins and caudal-fin lobes; extending from front of snout through eye and caudal-fin base is a midlateral dark brown to black stripe; another dark brown stripe commencing above eye and passing dorsally on body at base of dorsal fin; head and body between 2 stripes bright yellow, below white (Ref. 27362).
Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Poisonous canines provide considerable protection from predators.
