Diagnosis: The forewings are rather triangular, the hindwing centrally angled. The
male has the forewing ground a deep, dull rufous, mottled and diffusely
fasciated with dark brown. The discal spots are blackish. The female is smaller,
the forewings less produced apically, the ground colour paler, yellower.
Taxonomic notes. This, the next species and a smaller, undescribed species from Sulawesi
(slide 13418) are all characterised by a brush-like male hind tibia and a
strong, spur-like extension of the valve sacculus. The latter may be homologous
with the small, setose, angular process central to the ventral margin of the
valve in the type species of Zethenia. Paradarisa also has a process in
this position.
Geographical range. Borneo.
Habitat preference. The type material is labelled as from Lawas, a
northern Sarawak coastal town, but no altitude is given. Five specimens taken
during the Mulu survey were all from lower montane forest at 900m on the
limestone G. Api. The Sulawesi species is also characteristic of the lower
montane zone.
