Large numbers of melanophores in series on dorsal and ventral margins; typically, series on dorsal margin extends full length of tail; pectoral fin pigment pattern in flexion larvae. Pigmentation: Preflexion: initially, dorsally and ventrally on gut, about 10-25 in series on dorsal midline of tail (from postanal myomere 1-4 through 16-17), about 50-60 in series on ventral margin of tail (from postanal myomere 1 to 17); by 5.4 mm, at tip of lower jaw, laterally on upper and lower jaws (some specimens), above midbrain and nape, at otic region, laterally at cleithrum (some specimens), laterally on gut (some specimens), and 1 anterior to anus. Flexion: more above midbrain and nape and at otic region; at tip of snout; on pectoral fin base and dorsal and ventral margins of blade; 1 or more on lateral midline of tail (some specimens); internally above spinal column on tail.
