Diagnosis. The uniform dark brownish green coloration of the forewing, crossed by
faint bluish fasciae, and the broad banding to the hindwing costa distinguish
this species from other Bornean taxa. The forewing stigmata are often ringed
slightly with bluish grey or are totally cream or white.
Taxanomic note. White-spotted specimens from Sarawak match a colour slide of the
holotype (Kalimantan) exactly. Plain forms match a colour slide of the holotype
of mixtus, described from Sumatra. The genitalia differences between the
two forms noted by Holloway (1976) were found, on examination of more extensive
material, to be variable and insignificant, hence the names listed above are
brought into synonymy.
Geographical distribution. Borneo, Sumatra.
Habitat preference. The species is common, particularly in upper montane
forest, on G. Kinabalu, G. Mulu, G. Api, Bukit Retak and Bukit Pagon, on
Kinabalu it was recorded from as high as 2600 m. The white-spotted form was
found to be very much rarer in all these localities except G. Api, where it
predominated.
