Diagnosis.
The male has extensive pale grey areas on the forewing that distinguish it from other Bornean species. The female has a more extensive greenish brown area on the forewing and a marginal greenish brown band. The next species, Q. palladina Schaus, is similar but the male is smaller, darker grey, and the female much brighter with bright green markings more crisply defined.

Taxonomic note.
The species was identified from a rather poor photograph accompanying the original description. It is probably related to a mainland Asian taxon for which the name is obscure. A series of females from the N.E. Himalaya in the BMNH match well the illustration of Q. fasciata umbrosa Matsumura (Taiwan) in Sugi (1979); it is likely that umbrosa is a taxon distinct from fasciata.

Geographical range. Peninsular Malaysia, Borneo.

Habitat preference. The species is frequent in lower and upper montane forest zones, having been recorded from G. Api, G. Mulu, Bukit Retak and G. Kinabalu ( attributed to transcaerulea by Holloway (1976: Plate fig. 243)). It has also been taken in the lowland forests of Brunei at Labi and Ulu Temburong. It is montane in Peninsular Malaysia, the type locality, though it was described from one specimen only.
