Fins - D1 - VI, 1st and 2nd spines elongate to base of 7th ray D2 in larger specimens; not elongate in females; D2 - 12(11-13); pectoral - 18-19(17-20); anal - 10(9-11)

crossbars and wide, pale interspaces; distinction of color intensity between
the two less marked posteriorly. Body of holotype with 13 crossbars on
each side; paratypes with 13(12), 14(43), 15(5) dark bars from origin
of pectoral fin to caudal base. Narrow bars brown with a light median
streak containing usually one, sometimes two rows of darker brown or black
melanophores. Interspaces paler than brown crossbars because pale ground
color overlain by fewer uniformly distributed melanophores. Head crossed
by two V-shaped bars behind eye that cross over nape. Two bars on interorbital
space. One oblique bar below eye and indistinct dark blotches on snout.
Dark spots on lower half of head and on branchiostegal membrane. No dark
blotches on base of pectoral fin.
