توصيف مختصر كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري

خارهاي باله پشتي (کل) : 11; شعاع نرم باله پشتي (کل) : 21 - 22; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 16 - 17; مهره ها: 24. This species is distinguished from its congeners by the following set of characters: pored lateral-line scales 36-43; distal portion of the outer branch of first pelvic-fin soft ray a long filament, extending considerably from posterior contour of fin, first soft ray length 119%-123% of second ray; no black blotch on membranes associated with the first and second dorsal-fin spines; upper jaw naked, scaleless; pelvic-fin spine and first soft ray broadly whitish, and the remaining portions of fin black (in preserved specimens); the second black body band crossing pectoral-fin base, with no pale narrow interrupting lines; ocellated spot on dorsal-fin soft-rayed portion is more circular than oval, ratio of long axis/short axis of blotch 1.2-1.3 (Ref. 126057).
