Peruvian Butterflies

[Tony Hoare]

Does anyone know if Colias lesbia is found in the Urubamba valley,
upstream from Ollantaytambo?  I have taken some photographs of a
butterfly that is a dead ringer for C. lesbia pyrrhothea according to
D'Abrera Vol 1 Butterflies of the Neotropical Region p104. but the
distribution given doesn't seem to match.  My pictures naturally only
show the underside.
All the best
