توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 11; شعاع نرم باله پشتي (کل) : 16 - 17; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 8; مهره ها: 24. This species is distinguished from all its congeners by the following set of characters: D XI,16-17; A III,8; pectoral-fn rays 18-20; caudal fn rounded; auxiliary scales on body absent; ventral corner of preopercle with 2-4 relatively large spines; upper limb of first gill arch with 7-8 gill rakers; orbit diameter 4.1-5.0 in HL; short snout 5.3-6.7 in HL. Colouration: when freshly dead pale yellowish brown with fve, faint, dark brown bars interrupted dorsally with lighter coloration; darker brown irregular, squarish blotch approximately half way down each bar; a dark band across the operculum; small brown dots dorsally on head and anterodorsally on body; dark bars on body extending partially onto dorsal fin; dorsal, anal and caudal fins without dark margins (Ref. 122001).
Cross section: compressed.
This species is landed in trawling and longline fisheries at 28-93 m and this appears in commercial hauls and not common in fish markets in Hong Kong (Ref. 122001).
