( Figs. 9, 10 , 37 , 54 , 61 )

Sarawak Museum Journal, 3: 462, Pl. 15: 2. Type-locality: Borneo, Sarawak, Mt. Poi. Holotype, BMNH, London. Holloway 1982: 88, Pl. 29: 4; Holloway 2009: 74, Pl. 2: 30, Figs 127, 128.

Material examined. 1 female, Sumatra, 1–2. viii 1981 (E. W. Diehl leg.), genitalia slide: GB5643, female. Coll. G. Behounek, Munich.

Diagnosis. Adult ( Figs. 9, 10 ). Wingspan male, 19–21 mm, female 22–25 mm. Externally S. elegans could be confused with S. futii , but differs from the former by distinct spot-like orbicular and the shape of antemedial line. In male genitalia ( Fig. 54 ) it differs from S. futii by thinner valva, vestigial uncus and absence of ring of minute cornuti in basal part of vesica. Females ( Fig. 55 ) differ by the shape of antrum and bursa copulatrix.

Distribution. Indonesia, Sumatra, Borneo. Several generations per year.
