Olulis iuga Swinhoe

Marapana iuga Swinhoe, 1901, Ann. Mag. nat. Hist. (7), 8: 19.

Diagnosis

The forewings are a pale, slightly brownish grey, with strongly rounded distal margins, shaping the wing like an axe-head.

The postmedial consists of a series of darker flecks that curves strongly round a darker reniform mark, from which a darker shade extends into the postmedial.

The hindwings are slightly darker than the forewings above, but the reverse holds on the underside.

Taxonomic Notes

The facies is unusual within the genus, as are features of the male abdomen, such as the highly modified eighth sternite, the laterally expanded tegumen and the rather short and basally deep valves.

Geographical range

Borneo.

Habitat preference

This is an uncommon lowland species, taken in various coastal and dry heath forest associations in Brunei and 85 miles above (upstream from ?) Pontianak in Kalimantan.
