Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 65 - 72. Belly with 22 or 23 keeled scutes from isthmus to anus. Lower gill rakers with serrae enlarged near the tip and sometimes show clumping of larger ones along raker. Pectoral filament short, reaching to base of 1st to 15th anal fin ray; upper caudal fin lobe truncated, shorter than lower one. Pectoral fins with no dark markings, even in large fishes.
Apparently purely riverine. More data needed, based on separation from S. phasa.
