Rindge (1959) described eupetheciaria as four potential subspecies. The nominate form, mainly found in Arizona, Glaucina eupetheciaria eupehetciaria was described as similar to Glaucina escaria in most respects except size, being considerably smaller than that species. Form lucida, mainly found in the deserts of southern California, has lighter shading of forewings and more distinct maculation than the nominate form. Form osiana known only from extreme southeast Arizona and Mexico, have evenly dark forewings with almost no trace of AM/PM lines. Form escariola found from extreme southeast Arizona to southwest Texas, is the darkest form of the species, with the difference in females more pronounced including a broad dark terminal hindwing band.

Rindge (1959) listed the range to include southern California, to Clarke County, Nevada, Arizona, southern New Mexico, southwest Texas. (2)

Glaucina utahensis has a deeper indentation of the forewing PM line at the fold and male hindwings are white except for a band of gray shading at the inner margin.
