Papilio nubilus (Staudinger, 1895)

Keningau, N Borneo  Feb 1972  "nubilus"

    Felt to be of hybrid origin between P polytes and P nephelus albolineatus, but this has not to my knowlege, been proven. Specimens are exceedingly rare, and described from both Borneo and Sumatra.
 
P polytes alphenor (Philippines) P nephelus sunatus (Nias)
