This species is distinguished by the following characters: precaudal vertebrae 18-19; lower part of first gill arch with long gill rakers 13-14; pectoral-fin rays 19-23; HL:HD 1.85-2.09; most head spines are moderately strong or weak, present on ethmoidal, prefrontal, interorbital, supraorbital, sphenotic, inner preopercular rim and none on lacrimal, 5th infraorbital, supratemporal, inner and
outer posttemporal, outer preopercular rim; opercular spine sharp and extruding; opercular flap small; lower lateral line pores until beginning of anal fin 23; moderately broad dentition patch on vomer with 2-3 rows of teeth and on palatines with 2-4 rows of teeth; otolith with single colliculum; OL:OH = 1.17; OL:TCL = 2-3 (Ref. 125143).
Cross section: compressed.
Rare species (Ref. 34024). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
