Both this and the Clanis stenosema Rothschild & Jordan have rather
macroglossine build and wing shape, with a conspicuous paler brown
triangle based on the centre of the forewing costa. In bilineata the base is
less than one third of the length of the costa and apex is approximately a right
angle. In stenosema the base is considerably more than one third of the length
of the costa and the apex is obtusely angled; the pale triangle contrasts more
with the rest of the forewing in stenosema.
Taxonomic notes. The race of bilineata in Borneo is sumatrana Clark.
Geographical range. N. India to Korea, Japan, Borneo and Sumatra.
