Papilio sataspes
Papilio sataspes is a species of swallowtail butterfly from the genus Papilio that is found in Sulawesi and Banggai.

Description
Similar to Papilio iswara, but the 2. segment of the palpus black, the white area of the hindwing smaller, in two of the three sataspes-forms very much reduced above and entirely or almost entirely absent beneath;
the submarginal spots of the hindwing yellow, the 5. rarely indicated, commonly also the 3. and 4. suppressed.Celebes, Bangkai and Sulla Islands, not rare in the hills. — sataspes Fldr. (22 a) is distributed over the whole of Celebes. The white area of the hindwing above and beneath consists of 3 large patches, to which in the female is added a 4. spot, which is especially distinct beneath. — artaphernes Honr. The very much reduced white area of the hindwing only extends above to the 2. radial and is almost suppressed beneath. Bangkai; not known to me in nature. — ahasverus Stgr. (22 a), which is perhaps identical with the preceding, flies on the Sulla Islands,where the male is not rare; the area of the hindwing even smaller than in artaphernes, never reaching the 2. radial, beneath only the 2. spot indicated by a very thin line. In the female the area of the hindwing above is still narrower than in the and beneath there are 2 thin lunules in its place. Only known to me from Sulla-Mangoli.Karl Jordan in  Seitz.
