Fernaldella Ferguson, 2008

one of three species of Fernaldella in North America
Identification
Distinction from F. fimetaria is difficult as underside patterns in both vary, and upper sides are rarely photographed; genitalia are apparently similar. Images posted on internet web sites (when just underside is shown) may sometimes be misidentified (generally, if shown, the underside disc of the front wing of F. fimetaria should be a darker more even brown, and that of F. stalachtaria lighter, more yellowish, with darker cross-bands).
Upperside of F. stalachtaria is yellowish with indications of narrow dark cross bands. In F. fimetaria the upperside is more evenly brownish with yellowish markings near front edge of front wing.
It is conceivable that the two names represent color variations within a single species (?).
F. fimetaria is more wide-ranging across western North America from the Plains to near the west coast and from s. Canada to Mexico.
Range
Rocky Mountain region, Western North America (reported in literature from New Mexico, Colorado, Wyoming, and Oregon).
