This species presented itself to me in May 2019 at 1400m in the Sierra Nevada near Granada in Spain. They are small, even for a Pseudophilotes, but were flying plentifully in an upland scrubby pasture. Very active and easily disturbed, it took ages to snap presentable butterfly images.

I understand the white highlighting of the black forewing mark is a useful distinguishing feature of the species where it flies with panoptes.
