Diagnosis. Adult ( Fig. 15 ) with wingspan 14.0–23.0 mm. This species is similar to S. citrantha (Meyrick, 1908) by having a similar forewing pattern. It can be separated by the valva narrowed gradually and the transtilla having a pair of semioval lateral lobes ( Fig. 30 ). In S. citrantha , the valva is broadened semiovally from distal 1/3, and the transtilla has a pair of stout digitate lateral lobes ( Clarke 1955: Pl. 230, Figs 2–2 a).
