The green-blue spot in the cell of the forewing above reaches basad at least to the middle of cellule 2; forewing beneath without large yellowish submarginal spots, at the most with a few small spots near to the margin. Sierra Leone to the Congo region and Equatoria.

Description
Reflecting the confused separation between Papilio bromius and P. chrapkowskii. Very similar to P. chrapkowskii, but pale mottling and submarginal spots below not so well developed. Cilia of forewing black, not white, as in P. chrapkowskii. A somewhat unstable race with frequent transitions to the two previous races: P. bromius and P. chrapkowskii.
