Papilio syfanius (Oberthur, 1886)

Zhongdian, Yunnan, China; May 1984   ssp albimaculata Yunnan China ssp albomaculata
S Yunnan China  ssp albimaculata S Yunnan, China ssp albimaculata
Lhasa, Tibet; June 1953 Lhasa, Tibet; July 1990

     Restricted to southwestern China and Tibet. Generally rather rare and local, and consequently poorly known. There is still controversy as to whether syfanius represents a full species or only a well differentiated western subspecies of P. bianor. Quite variable even from the same locality in the amount of white on the hingwing.
