Diagnosis

Both sexes have a diffuse, oblique white band crossing the forewing from the centre of the costa to the tornal angle. See below for genitalic features.

Taxonomic Notes

The synonymy above is based on general facies similarities of the taxa concerned and, in the male genitalia, presence of a deeply bifid uncus and a broad, square, apex to the gnathus.

Leong & Aminurashid (2009) described and illustrated the final instar and metamorphosis of Amblychia hymenaria in Singapore. The larva is of a robust boarmiine type, irregularly mottled in medium and paleish grey and green with a sparse scattering of whitish dots. The primary setae are very short and arise from chalazae. The host plant was Cinnamomum (Lauraceae), adding to the records of genera from this family for Amblychia as listed in Part 11. Robinson et al. (2001) also included Styrax (Styracaceae).

Geographical Range

India to Sundaland, Sulawesi.

Habitat Preference

During the Mulu survey three specimens were taken in alluvial forest and one in kerangas in the lowlands just west of the Melinau Gorge. In Brunei a male and female have been taken almost at sea level at Labi, but a single female was recorded at 1618m on Bukit Retak.
