Diagnosis. The forewings are a dull orange red with a violet shade grading
into dark red at the distal margin. There is a dark discal spot flanked by fine
fasciae, the antemedial oblique, slightly sinuous, the postmedial more
transverse but obtusely angled basad subcostally. The hindwings are paler
orange-fawn, but also grade darker towards the margin.
Taxonomic note. All taxa brought into synonymy share a similar facies,
albeit with some variations in shade and development of the forewing discal spot
(see below), an unusually erect costal process to the valve and a relatively
distal position to the small cluster of spines and ductus ejaculatorius in the
aedeagus vesica. There is some regional variation in facies: purpurea has
a dark forewing; devia has a pale one; infundibulata is
intermediate with a more prominent discal spot. Kobes recorded both devia
(one specimen only) and infundibulata from Sumatra, but his genitalia
figures for both show the valve characteristic mentioned above.
Geographical range. S. India; N.E. Himalaya (ssp. devia); Peninsular
Malaysia, Sumatra, Borneo (ssp. infundibulata).
Habitat preference. Three specimens have been taken in dry heath forest and
one in dipterocarp forest in the lowlands of Brunei. Singletons have been taken
at 1000m (G. Mulu) and 1670m (Bukit Pagon) in montane forest.
