A yellow to whitish fangblenny with three black stripes along the head and body, a black submarginal band on the dorsal fin and a white underside. The Lined Fangblenny is found only on the Great Barrier Reef, Queensland.

Lined Fangblennies have a pair of venomous canines in the lower jaw that are used for protection against predators and to protect the blenny's territory - not for feeding. This species  is mimicked by the Yellow Sabretooth Blenny, Petroscirtes fallax, and juvenile Two-line Monocle Bream, Scolopsis bilineata.
