All three species in Borneo have similar sexual dimorphism and general
patterning as described above. In horridipes
the new species, the male hindlegs are longer and more densely invested with
long black scales. On the male forewing they both have a rather obscure paler
basal triangle with a distal edge that runs obliquely towards the costa. In pannicula
this triangle is paler, and its distal edge continues asymptotically distad
along the costa. In the females, pannicula has the distal dark area of the forewing
with a rather angular basal boundary that meets the dorsum obliquely, whereas
the other two species have this boundary more evenly curved anteriorly and
meeting the dorsum more or less at right angles. In horridipes
distal black zone of the forewing is uniform, whereas in the new species it
combines a double, paler, ripple-like mark in both sexes (see also the diagnosis
below) in typical Sundanian species (Himalaya and Chinese specimens resemble horridipes

preference. The species is infrequent in lowland forest and extends more
rarely to as high as 1500m.
