Papilio machaon from Sichuan, Identification please.

Since we're already a bit off-topic, the dashed red "phylogenic uncertainties": does that mean the uncertainty likes only within those nodes enclosed in the red box, or the entire tree?

For example, hospiton and zelicaon are on branches that meet, and are far off from the higher level branch that eventually leads to brevicauda. Does the red box mean that the close relationship of hospiton and zelicaon is in question, or that those are indeed as shown, but the ancestral tree at a much higher level is unclear? i.e., Clades 3b and 3c may be all one clade, or the extant species under them may not be at all as shown?

Thank you!

This is explained in the paper - different analyses produce slightly different linkages between the clades but do not affect the relationships between species in each clade and subgenus. The red dashes indicate the area where alternative topologies have been found and further investigation of the higher classification within this part of the genus is needed.

All analyses produce the same topology between the clades outside the red dashes, and the clades (3a, 3b & 3c) all definitely belong there relative to the others, but different methods can produce trees with these three subgenera in different positions relative to each other. For example in some analyses clade 3c is basal to 3a and 3b. The published tree with regard to the relative positions of these 3 clades is the best supported under the analysis in the paper.
