I've got several specimens farmed in Xishuangbanna, Yunnan. And some of them are malformed but with very interesting phenotypes. This tailed one is asymmetrical but the white pattern on hindwings is different with typical f. distantianus. The pattern seems much like the one of female P. agenor mayo ^0^, especially it has very slender tails.

This malformation of the forewing costa was caused by incomplete closure of the forewing case on the right side of the pupa after shedding the pre-pupal skin.

If these specimens originate from southern Xishuangbanna the white inner hindwing edge is part of the mimicry of Losaria doubledayi which occurs nearby in Laos. This is true f. distantianus, whereas the darker form which mimics Pachliopta aristolochiae in China is called alcanor. Form alcanor particularly has a short white patch inside the hindwing cell, whereas distantianus has an elongate white patch in the cell.

Adam.

PS. Note that mayo is now a subspecies of Papilio memnon, rather than a separate species, and does not belong to P. agenor.

Thanks, Adam. About f.alcanor, I've got a specimen without white patch inside the hindwing cell, recently.

Sorry for my mistake T-T
