Diagnosis. This species is the only grey and white member of the genus in Borneo.
It differs from other similar small whitish Bornean species in the Nygmiini in lacking a discal spot on the forewing. The hindwings are
grey except at the margin in the male. Probable females have this hindwing grey
much reduced. Parts of the body have a rufous tinge.
Taxonomic note. The male genitalia lack the rugose protrusion ventral to the rather
elongate uncus but have valves and a saccular flap typical of the genus, the
latter well developed. The rugose protrusion is replaced by a bifid process.
Geographical range. Borneo.
Habitat preference. The holotype was taken at 1500m on the Pinosuk
Plateau (Mesilau) of G. Kinabalu. Two possible females were taken at 1930m near
the Power Station.
