Morphology | Morphometrics
soft rays: 8;
Vertebrae: 26. This species is distinguished from its congeners by the following combination of characters: D1 I,8; pectoral-fin rays 18-19; predorsal scales 8-12; longitudinal scales 29-31; vertebrae 11+15 = 26; predorsal squamation composed of large ctenoid scales, reaching anteriorly to near posterior
margin of the eye; short transverse rows of sensory papillae 5-6 below eye; several short transverse
rows of sensory papillae (a part of row c) between 2 longitudinal rows of sensory papillae on cheek; head with a dark brownish gray reticulation or reddish oblique lines except for its ventral surface; upper end of pectoral-fin base with a black spot, as large as pupil; midlateral body with a longitudinal series of alternating large and small black blotches; 2-4 irregular longitudinal rows of small skyblue spots on midlateral body when alive (Ref. 104791).
