🐟 Physical Description

Dorsal spines (total): 7; Dorsal soft rays (total): 10 - 11; Anal spines: 1; Anal soft rays: 9 - 10. This species is distinguished by the following set of characters: no scales on cheeks, opercle and nape; second spine of the first dorsal fin elongated, reaching posteriorly to the base of the 2nd-10th ray of the second dorsal fin when adpressed; pectoral-fin rays 17-18 with 12-13 branched rays in the middle of the fin; a single dichotomous branch point in the 5th pelvic-fin ray, its length 51-75% the length of the 4th ray; total gill rakers 17-18; beneath the eye 5 papillae in row c; midline between the base of the first dorsal spine and the posterior interorbital region is a very well developed dermal crest; a U-shaped interorbital trench with no fleshy median ridge; a poorly developed postorbital trench ending between the 4th to 5th papillae in row p (which has 6 papillae in total). Colouration when alive and freshly collected is very similar in appearance to T. sheppardi, body overall yellow with three yellow bars across the cheek, and a double dark spot above the posterior portion of the opercle .Cross section: oval.
