cosmoloma Prout, 1928, Sarawak Mus. J., 3: 468.
The species occurs in two forms that both have a series obliquely set but
diffuse, faint brownish fasciae on a fawn ground. The doubled postmedials are
slightly more intense within this, and distal to them occurs the shading that
distinguishes the two forms. One has a slightly darker ground, with this shading
faint and restricted to the forewing, though there is a darker spot subtornally
on the hindwing. The other has a paler ground with more intense shading in
violet brown within the anterior half of the marginal area of the forewing and
in a gentle curve from the apex of the hindwing to where its postmedial meets
the dorsum; subdorsally, just distal to the postmedial, is a dash of pale ground
colour. It is possible that two species are involved, but no obvious differences
were found in their male genitalia. The holotype of cosmoloma

Only the heavily marked form is known from Sulawesi, a singleton. Only the more
uniform form has been seen from Java.

preference. This is an infrequent lowland species, found in both pristine
forest and disturbed habitat. It was the commonest member of the genus recorded
by Chey (1994) in lowland softwood plantations in Sabah. The highest record is
from stunted hill forest at 900m on Bukit Monkobo, Sabah.
