Polyura is a subgenus of butterflies also referred to as Nawab butterflies [1] [2] 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. [3] [4]
Polyura butterflies are native to the Indomalayan and Australasian realms. 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. [2]
The genus Polyura was synonymized with the genus Charaxes in 2009 in a study investigating phylogenetic relationships among Charaxini using DNA sequencing. [3] 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 . [3] [4] Southeast Asian species of the genus Charaxes do not seem to be closely related to species of the subgenus Polyura. [3]
A comprehensive molecular phylogeny of the subgenus as well as several taxonomic studies have allowed a complete revision of the group. [4] [5] [6] A follow-up study investigating the biogeographical history of the subgenus suggested an origin in the Miocene about 12 million years ago in mainland Asia. The Australasian region was colonized later through dispersal.
The subgenus is divided in three morphological groups supported by molecular phylogenetics: [4] [5] [6]
P. athamas group:
P. eudamippus group:
P. pyrrhus group:
Polyura athamas, the common nawab, is a species of fast-flying canopy butterfly found in tropical Asia. It belongs to the Charaxinae in the brush-footed butterfly family (Nymphalidae).
The Charaxinae, the leafwings, are a nymphalid subfamily of butterflies that includes about 400 species, inhabiting mainly the tropics, although some species extend into temperate regions in North America, Europe, China, and southern Australia. Significant variations exist between the species. For example, some are medium sized and bright orange above, but mottled gray or brown below. This underwing coloration helps them resemble a dead leaf when they are at rest, as they keep their wings closed. With relatively few exceptions, the hindwings of the members of this subfamily have jagged edges.
Polyura arja, the pallid nawab, is a butterfly belonging to the rajahs and nawabs group, that is, the Charaxinae subfamily of the brush-footed butterflies family.
Polyura eudamippus, the great nawab, is a butterfly found in India and the Indomalayan realm that belongs to the rajahs and nawabs group of the brush-footed butterflies.
Charaxes agrarius, the anomalous nawab, is a butterfly found in Asia that belongs to the rajahs and nawabs group, that is, the Charaxinae subfamily of the brush-footed butterflies family. The name is based on their resemblance to the common nawab, which was described before the discovery of this species.
Polyura dolon, the stately nawab or stately rajah, is a butterfly found in the Indomalayan realm belonging to the rajahs and nawabs group, that is, the Charaxinae group of the brush-footed butterflies family.1983
The rajah and pasha butterflies, also known as emperors in Africa and Australia, make up the huge type genus of the brush-footed butterfly subfamily Charaxinae, or leafwing butterflies. They belong to the tribe Charaxini, which also includes the nawab butterflies (Polyura). Charaxes are tropical Old World butterflies, with by far the highest diversity in sub-Saharan Africa, a smaller number from South Asia to Melanesia and Australia, and a single species in Europe. They are generally strong flyers and very popular among butterfly collectors.
Charaxes brutus, the white-barred emperor or white-barred Charaxes, is a butterfly of the family Nymphalidae. It is found in Africa.
Charaxes druceanus, the silver-barred emperor or silver-barred charaxes, is a butterfly of the family Nymphalidae. It is found throughout tropical Africa.
Charaxes legeri, the St. Leger's charaxes, is a butterfly in the family Nymphalidae. It is found in southern Burkina Faso, northern Benin, northern Nigeria and southern Niger. The habitat consists of woodland savanna at altitudes between 600 and 1,700 meters.
Charaxes hansali, the cream-banded charaxes, is a butterfly in the family Nymphalidae. It is found in Tanzania, Rwanda, Kenya, Uganda, Sudan, Ethiopia, Somalia, Saudi Arabia, Yemen and Oman.
Charaxes antiquus is a butterfly in the family Nymphalidae. It is found on the island of São Tomé. The habitat consists of forests and woodland. The species was named by James John Joicey and George Talbot in 1926.
Charaxes pollux, the black-bordered charaxes, is a butterfly in the family Nymphalidae.
Charaxes dowsetti is a butterfly in the family Nymphalidae. It is found on the Nyika Plateau in Malawi. The habitat consists of montane forests at altitudes above 2,200 meters.
Charaxes lucyae is a butterfly in the family Nymphalidae. It is found in Tanzania.
Charaxes musakensis is a butterfly in the family Nymphalidae. It is found in Cameroon. The habitat consists of montane forests at altitudes above 1,300 meters.
Charaxes (Polyura) alphius, or Staudinger's nawab, is a butterfly in the family Nymphalidae. It was described by Otto Staudinger in 1886. It is found on Timor and Sulawesi near the Wallace Line. Polyura alphius has been considered a subspecies of Polyura athamasPolyura athamas alphius.
Polyura narcaeus, the China nawab, is a butterfly in the family Nymphalidae. It was described by William Chapman Hewitson in 1854. It is found in the Palearctic and Indomalayan realms.
Charaxes (Polyura) caphontis is a butterfly in the family Nymphalidae. It was described by William Chapman Hewitson in 1863. It is endemic to Fiji. The only species of the genus [Eriboea (Polyura pars]with a reddish-brown double-row on the upper surface of the hindwings. The under surface of the male is dark chestnut brown, of the female greyish-brown. The markings of the upper surface are repeated, except the greenish band of the hindwings, which, moreover, in the female consists only of a thin line on the upper surface. Flying time according to Woodford in November, the rainy period, in the Fidji Islands. According to Rothschild and Jordan there are also males with a yellowish median band being distinctly pronounced also on the under surface of the hindwing
