Dorsale zachte stralen (totaal) : 9. Diagnosis. This species is distinguished by the following set of characters: 9 dorsal-fin soft rays; fourth fin spine longest; 17 pectoral-fin rays; 39-44 longitudinal scales rows; 23 pored lateral-line scales; lateral surface of trunk covered with ctenoid scales; anteroventral surface of body and pectoral-fin base covered with exposed cycloid scales; lateral surface of maxilla with no longitudinal ridge; no spines on lateral surface of lacrimal; posterior margin of anterior lacrimal spine with 1–3 small spines; simple posterior lacrimal spine directed ventroposteriorly; no median interorbital ridge and no coronal spine; with occipital pit and supplement preopercular spine; relatively short fin spines and rays, longest pectoral-fin ray (31.5-33.5% of SL); the space between the upper and lower opercular spines is not covered by skin with sensory pores and canals; length of supraocular tentacle is less than or approximately equal to pupil diameter; no tentacles on lateral surface of trunk, except on pored lateral-line scales (Ref. 75652).
