tyche in North America ?

[Kondla, Norbert FOR:EX]

A few years ago a North American book introduced the name Colias tyche to
North America and included taxa like Colias boothi etc in the concept of
tyche without really explaining why we should accept that interpretation. I
vaguely recall someone on this list (from Europe?) expressing disagreement
with that interpretation.  I am interested in any thoughts and especially
data or publications on the topic of the relationships between tyche,
nastes, boothi, thula etc group of butterflies. Thank you.
