The upperside is dark chocolate-brown with a row of 4 to 5 subapical dots surrounded by a diffuse, rust-orange patch. The underside has a greyish frosting, with a faint, slightly darker median band and a white median spot; no hindwing eyespots. The only similar species in Alberta is the Common Alpine (E. epipsodea), but the latter always has hindwing eyespots. There are no described subspecies; the Taiga Alpine was thought to be the same species as E. disa until Layberry et al. (1998) provided evidence of separate species status. The type locality of mancinus is Rock Lake, near Jasper, AB.

Undescribed. Adults fly among partially shaded, open spruce stands in spahgnum bogs, and are often found together with Jutta Arctics. The life cycle takes two years to complete, and adults may be present only in alternate years at a particular site (Klassen et al. 1989).
