Diagnosis

This is the smallest Bornean Amata. In facies it is not dissimilar to A. pleurosticta Hampson but has all wing markings more elongate, with the black separating them narrower. The posterior distal transparent patch is divided by vein M3; sometimes the anterior patch also extends to beyond vein R5. Each abdominal segment is ringed finely and evenly with yellow. The male genitalia are distinctive.

Taxonomic notes

Bornean material referable to sala shows no genitalic differences from typical Javanese huebneri, though the transparent patches on the hind-wing and at the base of the forewing are somewhat larger.

Geographical range

Indo-Australian tropics to N. Australia.

Habitat preference

The specimen illustrated is from the lowlands of Sarawak near Kuching; the series of sala is from Kinabalu, but no altitude or habitat details were recorded.

Biology

The larva has been found feeding on rice in Java (CIE records).
