Diagnosis and taxonomic
note. This and the next species are
related to each other but not true Scaptesyle as strictly defined above.
The forewing facies is yellow, with apical and basal zones of black centred with
dull red, but the hindwings are not yellow, and lack a black border, being pale
bone-white, grading brownish towards the margin. The forewings are more
rectangular in shape, and, unlike in the Scaptesyle generic quartet, the
dark areas of the upperside are expressed much more weakly on the underside. The
facies is similar to that of “Garudinia” successana Walker
from Seram and the genus Parascaptia Bethune-Baker
from New Guinea. The male genitalia have very elongate lobes to the tegumen. The
saccular process is flexed and characterised by a group of setae just basal to
the point of greatest flexure (distinctly articulated in Parascaptia).
The inter-saccular setal plate is relatively small, the setae dense (broad,
with coarse setae in Parascaptia). The apodemes on the
eighth abdominal segment are well separated (basally fused in Parascaptia). The two species are
distinguished in the diagnosis following.
Geographical
range. Borneo.
Habitat
preference. The
species is rare, taken in lower montane forest during the Mulu survey (1000m on
G. Mulu, 900m on G. Api), but also with singletons from 150m and 500m on the
Mulu transect. Older material is from lowland Sarawak in the area of Kuching.
