7-8mm. The wing markings are as in typical insolata, though not
so clearly defined, and the forewing postmedial is narrower. The central element
of this is contiguous with the rest and of even width as in insolata. In S.
pedilata Felder (Sri Lanka, Bali) it is broader, of more even brown tone,
and with constrictions separating it from the rest of the fascia. In the male
abdomen, the cerata of the eighth sternite are of unequal length (left, half
of right and more strongly curved) in typical insolata, but more or less
equal, long in the Bornean race.
