Diagnosis

The shape of the swim bladder is not distinguishable from that of S. ciliata. The anterior part of the swim bladder has rudimentary tubules projecting anteriorly and a lateral series, that diminishes in size and becoming sawtooth-like, projecting posteriorly. Body is light silvery, slightly darker to dusky dorsally. A dull golden silver to golden yellow stripe is below the lateral line. The pelvic and anal fins are pale yellow to bright yellow; the pectoral fin has a darker dusting of fine black-brown spots.
