Hypochroma polyphaenaria Guenée,
1857, Hist. nat. Insectes, Spec. gen. Lep., 9: 280.
Dindica basiflavata Moore,
1868, Proc. zool. Soc. Lond., 1867: 632.
Diagnosis. This and the next species resemble each other closely and are best
distinguished by genitalia characters. However, the forewing postmedial is less
strongly angled in polyphaenaria, meeting the costa at a less acute
angle, and within this angle there is usually a quadrate dark mark in olivacea.
Geographical range. Himalaya, S.E. Asia, Sundaland.
Habitat preference. The only Bornean specimen seen is from Bidi in the lowlands of
Biology. The larva has been described by Sevastopulo (1946), with details of
chaetotaxy by Singh (1956). It is leaf-green, the setae set on white
points and the skin generally granulate. There are subdorsal yellow-white and
lateral white lines over the abdominal segments, with obscure, oblique white
lines between them. There is also a narrowish yellow ventral stripe with similar
oblique yellow lines between it and the lateral line. The spiracles are dark
Pupation is in a leaf
folded and spun together.
The host-plant (Singh,
1956) is Litsea (Lauraceae), the larva feeding in young foliage.
