Diomea orbifera Walker 

Zigera orbifera Walker, 1862, J. Linn. Soc. (Zool.), 6: 182

Zigera lichenosa Hampson, 1898, J. Bombay nat. Hist. Soc., 11: 460,*

Diagnosis

The forewing facies is somewhat similar to that of absorbens, with a pale-edged central patch, but this never reaches the distal margin. The hindwing is much darker, with an irregular pale band medially and a fainter one submarginally.

Taxonomic note

The holotype male of lichenosa Hampson (Sikkim) has facies and male genitalia as inorbifera. The features of the male genitalia ofD. ferrosticta Yoshimoto (Burma) suggest a close relationship to orbifera, which is variable in the development of pale areas on the wings; in ferrosticta these are not evident.

Geographical range

Borneo, Thailand (VK), Sikkim.

Habitat preference

The holotype was taken by A.R. Wallace in Sarawak. Three specimens have been taken recently in Brunei, all from lowland forest: dipterocarp forest at 100m and 300m in the Ulu Temburong; heath forest at 15m at Telisai.
