Differs from the similar Cocky Gurnard, Lepidotrigla modesta, in having a broad reddish band on the rear half of the caudal fin (vs most of caudal fin red in L. modesta), a reddish-orange margin on the inner surface of the pectoral fin (vs a blue margin in L. modesta),a larger eye (eye diameter 33–37% HL vs 20–32% HL in L. modesta), and fine serrations on the first dorsal-fin spine (vs coarse serrations in L. modesta), |
