Tropical South America, widely distributed, but only singly among the white butterflies of this group.

hetaerius R & J Easy to differentiate from the preceding form by the thinner black bands; it is so similar to the protesilaus forms occurring together with hetaerius as to be easily mistaken for them, but is much smaller than the Colombian protesilaus and has a much less sharply dentate hindwing.

Guiana, Amazons, Colombia, Ecuador (except the western side), Peru and Bolivia.

megalurus R & J Antenna black as in the Brazilian protesilaus: frons laterally white; the white subdorsal line of the abdomen thin; 1. and 2. band of the forewing extend to the hindmargin, 6. band separated from the angle of the cell; the black markings of the hindwing somewhat more developed than in hetaerius, the red anal spot longer; tail long and broad.

hetaerius R & transferred to P. macrosilaus and replaced in P. molops by leucosilaus (Zikan) by Hancock [3]
