4 vertebrae to vexillum origin; about 18 anal fin rays to dorsal fin origin; about 37 dorsal fin rays to 31st vertebra; prevexillum length less than about 1.4x HL; vexillum well anteriad of first dorsal fin ray; maxilla free and movable; pigmentation absent from lower jaw and gular region; fine row along base of anal fin ray. Pigmentation: Preanal fin formation: by about 3 mm TL, over brain between eyes, under brain posterior to eyes, anteriodorsally on gut, and 2 ventrally near end of tail; by about 5.5 mm, on isthmus, vexillum, and ventrally on tail. Anal fin formation: 1 (minute) anterior to base of anal fin rays, on vexillum, a few specks dorsally near end of tail, one speck dorsally on fore and midbrain. Sequence of fin development: dorsal and anal, pectorals, caudal. |
