57. Meandrusa payeni ( Boisduval, 1836)

Papilio payeni Boisduval, 1836 ; Spec. Gén. Lépid., 1: 235; TL: ‘Java’ [Java, Indonesia].

Note: Examination of type specimens in NHM, London, and numerous specimens from Yunnan, Myanmar and Indochina shows that previous published distributions for the two subspecies in the region are incorrect. The phenotype of subspecies amphis ( Jordan, 1909) is orange-brown with brown margins whereas subspecies langsonensis (Fruhstorfer, 1901) has a pale orange or yellowish discal band with broad dark brown margins ( Figure 9 ). The difference in forewing margins is especially obvious in the female. The correct distributions of these subspecies are listed below. Monastyrskii (2007) illustrated a specimen similar in markings to ssp. amphis but the ground colour of the discal area in ssp. amphis is brown rather than yellowish. The yellowish band on the upperside of Monastyrskii’s specimen does not clearly come through in the plate, but it is still clearly visible. Both of these specimens belong to the wet season generation, so they are quite similar in pattern. Dry season specimens of ssp. amphis are much more like the female ( Figure 11B ) in wing pattern, with a narrow brown forewing margin, very different to ssp. langsonensis , and the ground colour is orange-brown, not yellowish.
