Similar Species

Often misidentified as Synodus variegatus, which has the cheek fully scaled behind the mouth to the edge of the preopercle (vs cheek usually not scaled to preopercular margin), and has a short triangular flap on the anterior nostril (vs a long and slender flap of S. dermatogenys).
Differs from the similar Streaky Lizardfish, Synodus similis (which also a blue stripe along the side) in lacking a black spots or a black blotch on the upper rear part of the gill cover.
