Metorthocheilus emarginatus Hampson;
Holloway, 1976: 86.
Diagnosis. The forewing margin is strongly excavate subapically, such that the wing
apex is almost bifalcate. The hindwings are narrow, triangular. The ground
colour is grey, irrorated browner, and there are pale discal spots on fore- and
hindwings. The latter have two fine dark lines running parallel to the straight
margin.
Taxonomic notes. Material from Seram (slide 400) has a much smaller spine-like distal
production of the valve costa than in the Himalayan specimen illustrated.
Geographical range. Indian Subregion, Taiwan, Borneo, Java, Seram.
Habitat preference. The only Bornean specimen was taken at 1930m (upper
montane zone) on G. Kinabalu.
Biology. The species has been reared in Taiwan (Chen, 1997). The larva is
cylindrical, with a rufous head and a translucent greyish body with black spots
on the head and ringing each segment.
The host-plant was a species of Wendlandia (Rubiaceae).
