16-17mm. The size and dark blue colour are as in montana but the
species has the forewing margin straighter, and also the diffuse postmedial. The
hindwing ocellus is elliptical, oblique, the black centre very narrow and the
yellow surround very much broader on the anterior side of the ellipse. The male
genitalia are similar to those of montana but the aedeagus lacks a bundle
of cornuti in the vesica.
