How did you rule out C. teligera?

Looking at the revision for the genus, the orange line looks thinner in teligera, and the posterior silvery bands are thinner as well while the bands on my individuals are certainly not thin. Plus, the diagram for teligera shows the three white lines closer to the costal margin are layered on top of one another, whereas mine are staggered, as in the diagram of lespedezae. Plus, the white line closest to the costal margin is very small in the teligera diagram, whreas it is long in the lespedezae diagram. Finally, according to the revision, teligera is a more southerly species.
I don't see why it is not lespedezae.

I've noticed a lot of discrepancies between Koster's
descriptions and figures. I would take both with a grain of salt. I have not found a reliable way to separate the two without dissection. The range may help at least a little, but I would be hesitant to place this at the species level (for now).
