So far six people have been convinced that the one on the left is Charaxes pollux. So case closed there.

One reply stated that the one on the left could be C.brutus (Not: orange head, Brutus is brown colored, and b) C.ethalion (Not so:C.ethalion is a small black charaxes, quite different)

But there is far less agreement on the one on the right: one reply said it was probably Charaxes numenes ugandensis (say 80 % chances). Another expert said it was either C. bipunctatus or C. tiridates but certainly not numenes, ("as numenes has a continuous light line on the underside which is broken up in C. bipunctatus and C. tiridates. So it would be necessary to see the upperside to distinguish between bipuncatus and tiridates. The same contributor also suggested a third possibility for the one next to C.pollux: "Charaxes smaragdales is occurring in Kibale at very low densities, but still, a small chance exists that you will encounter it. The underside of this species is very similar to bipunctatus and tiridates".
One reply stated that it was Charaxes cithaeron, while another stated it was Charaxes tiridates, adding that the middle one behind was Charaxes ethalion. Yet another contributor was of the opinion that the one next to C.pollux was C. xiphares burgessi or smaragdalis ("xiphares is an altitude sp and then may be not the good biotop). tiridates may be but is not his jizz.").

I wish to thank Mr Owen Burnham, Mr Michel Pierson, Mr Gilles Faravel, Mr Freerk Molleman, and Mr Thierry Bouyer for their comments.

But what do you think?

The one on the right, which one is it?(Charaxes tiridates, bipunctus,numenes, smaragdales, cithaeron, xiphares ?)
