Closely related to congenerics but distinguished by the combined absence of an adipose fin and presence of a coarsely serrated inner side of the pectoral spine (Ref. 43912).
Coloration: silvery, more or less dotted with irregular and star-shaped deep brown chromatophores dorsally and laterally (Ref. 43912). Preserved specimens: body pale and opaque (Ref. 43912). Head, sides (particularly along lateral line and between lateral line and base of anal fin) and especially back, covered with small, brownish-black spots (chromatophores); anal fin and pectorals also slightly spotted; belly and pelvic fins unpigmented (Ref. 43912, 57127). |
