Diagnosis. The forewings of the male are more uniform brown than in the next
species, with the rather straight, diffuse submarginal having a bronzy sheen.
The interior margin to the subapical triangle meets the costa at a wider angle
than in the next species, a character that is also diagnostic for females. In
the male genitalia the furca blades are over half as long as the valves, whereas
in the next species they are less than half as long. The spines at the apex of
the aedeagus are on average more numerous in cupreistriga. In the female
genitalia the setose lobes of the ninth sternite are apically squarish rather
than triangular.
Taxonomic notes. A similar taxon flies in Sumatra (slide 285) with S. nitens Walker
(see below).
Geographical range. Borneo, ?Sumatra.
Habitat preference. The species has only been taken in the lowlands from
habitats such as alluvial forest, mangrove, hill dipterocarp forest and coastal
associations; it is probably also to be found in secondary vegetation and
cultivated areas.
Biology. No information on the life history of Bornean Setora has been
located. The species illustrated by Wood (1968) is probably nitens Walker
as are the larvae described and illustrated by Piepers & Snellen (1900) and
Kalshoven (1950, 1981).
