Differs from other species of Sewellia by the following combination of characters: body spotted, without dark stripes; without concentric band on paired fins; pelvic fin reaching to anal-fin origin; pelvic-fin origin below dorsal-fin origin; small soft elevated patches of fine tubercles on first pectoral-fin rays in males; tubercles on simple pectoral-fin ray not enlarge; absence of cavity around mouth; absence of skin-fold between oropectoral membrane and ventral surface of head; and 50-60 lateral line scales (Ref. 40433).
