Taxonomic Notes

Watson (1967) rejected the above synonymy on grounds of colour pattern differences, despite the similarity of wing shape (more bifalcate in both sexes than in fulgens). However, recent collecting has only accumulated a long series of males and two more females that match subrosea and rubromarginata respectively, rather than alternative ‘marriages’ for either.

The sexual dimorphism is slightly more extreme than in fulgens.

Geographical range

Borneo, Sumatra.

Habitat preference

This is more strictly a lowland forest species than fulgens, sharing a preference for alluvial forest and forest on limestone during the Mulu survey.
