Diagnosis. The forewing has a distinctly darker
medial band, the inner border of which is angled much closer to the costa than
in the next three species. The area of the wing on each side of this band,
particularly at its very edge, is delineated with pale mauve tracery. The dark
brown submarginal forms a distinct rectangular patch at the apex of the wing,
which it approximately bisects, and at the inner end of this patch there is a
faintly paler bar; the rest of the submarginal is much finer and more
irregular. Males are characterised by a longitudinal pale streak subcostally
just distal to the medial band.
Taxonomic note. An externally similar species, S. buruensis Prout, with
differences in the male genitalia (Berio & Fletcher, 1958) is found in
Sulawesi, the S. Moluccas and Australia
(Nielsen et al., 1996).
Geographical range. Himalaya,
Borneo, Peninsular Malaysia, Sumatra.
Habitat preference. The species has been recorded
infrequently in lowland forest, with single specimens taken at 1000m and 2360m
on G. Mulu.
