Taxonomic Notes

Warren comb. n. (Nilgiri Hills, S. India) is a more uniform species with more regularly defined fasciation. The forewing antemedial is less strongly but more evenly curved, such that the medial band is narrow. Only female specimens are known, but the genitalic features are consistent with placement in Oroplema. The type species, dealbata Warren, has similar facies to oyamana, but the male genitalia have the uncus more robust, strongly flexed at the base, and the valves are much narrower.

Geographical Range

Taiwan, Japan, N.E. Himalaya, Peninsular Malaysia, Borneo. Philippines (Luzon).

Habitat Preference

All records are from the upper montane zone on G. Kinabalu.

Biology

The larva, reared in Taiwan (Chen, 1997), is more slender than those in other genera, cylindrical, dull black except for the glossy chalazae bearing primary setae, and translucent pale orange and grey patches ventral to the spiracles on the abdominal segments and dorsally on A8. The host-plant recorded by Chen was a species of Daphniphyllum (Daphniphyllaceae).
