I vacillated a bit over this one, Ken, not that I doubt the ID, but just that a fresh female calcaris can be very similar to a female icteromelas, and ideally you need a good side-on view of the thoracic patterning. On balance, I think what you can discern from the first photo (of a female) points to calcaris; and I've no doubt about the male in the second photo being calcaris. To further complicate the situation, both A icteromelas and A calcaris, as well as Griseargiolestes intermedius (Alpine Flatwing), all occur at this precise location.
