The forewing facies is similar to that of the previous two species except the
area basal to the black marginal zone is more variegated with more irregular
transverse fasciation and shading of vinous brown. The hindwings are dark grey

preference. The original specimen of tuhanensis was
taken in an area of cultivation and forest remnants at 1200m on G. Kinabalu, but
most material recorded subsequently is from lowland forest where the species is
frequent. Chey (1994) recorded the species commonly in secondary forest and
softwood plantations in the lowlands of Sabah. Martini & Thöny (1993)
recorded it from 800m at Sipulut and from 950m on G. Trus Madi in Sabah.
