Polyura is a subgenus of butterflies also referred to as Nawab butterflies and belonging to the brush-footed butterfly subfamily Charaxinae, or leafwing butterflies. Like the large and conspicuous forest queens (subgenus Euxanthe), they belong to the genus Charaxes, unique genus of the tribe Charaxini.
Polyura butterflies are native to the Indomalaya and Australasian ecozones. They are widespread from Pakistan to Okinawa Island, and from China to Pacific Islands (Fiji, New Caledonia, Vanuatu).
The subgenus was revised in 1982 by Robert Leslie Smiles based on morphological characters.
The genus Polyura was synonymized with the genus Charaxes in 2009 in a study investigating phylogenetic relationships among Charaxini using DNA sequencing. However the genus Charaxes comprises many morphologically very different groups such as the subgenera Euxanthe and Polyura. A phylogenomic study is ongoing to resolve the phylogenetic placements of these different groups. The sister-group to Polyura seems to comprise the African species Charaxes paphianus and Charaxes pleione. Southeast Asian species of the genus Charaxes do not seem to be closely related to species of the subgenus Polyura.
