Amblychia angeronaria Guenée,
1857, Hist. nat. Insectes, Spec. Gen. Lep. 9: 215.
Diagnosis. This and the next species are easily confused. A. angeronaria is
paler, browner, often mottled with ochreous in the male, rather than grey,
fasciated with brown. The fovea is present in angeronaria, absent in infoveata.
The females are a more orange-brown in angeronaria. The medial
fasciae are narrow, clearly defined in angeronaria, broader, more diffuse
in infoveata. The forewing antemedial is somewhat more oblique to the
dorsum in infoveata, and the hindwing margin is more strongly and broadly
excavate between Rs and M1. The underside is paler, more ochreous in angeronaria,
with the forewing postmedial dark band more or less straight rather than
curved with the concavity distad as in infoveata. No reliable genitalic
differences have been located.
Taxonomic notes. A. torrida Moore (Andamans) is probably distinct, having the
diffuse medial of the next species and a less produced, more regularly excavate
Geographical range. N.E. Himalaya to Taiwan, Borneo and Sumatra.
Habitat preference. Most records are from the forests of the lowlands,
during the Mulu survey with some preference for alluvial forest and kerangas.
Biology. The larva in Taiwan is illustrated by Sugi (1987) as discussed in the
introduction. It is ochreous, mostly suffused cinnamon grey-brown except for a
few, large, irregular, diffuse patches of ground colour on the flanks. The host
plant was in the family Lauraceae.
