McDunnough, 1922) original description,

"Size and general maculation of glitranana Kft. but of a much darker appearance, due to the fact that the pale areas between the dark bands are only slightly lighter in color than the bands themselves. Basal area of primaries black, overlaid heavily with brown and ochreous scaling and interrupted by several bluish-silvery dots; median band similar in color to basal area, in shape much as in glitranana; the paler space between basal area and median band is defined by two subparallel bands of bluish-silvery spots the included area being scaled with brown, without the underlying blackish color. A triangular anal spot and broad subapical band similar in color to median band, all their edges defined by silvery scaling; remaining areas similar to antemedian band in color. A row of dark spots along costa bordered with pale ochreous and a dark terminal line. Fringes deep smoky, slightly paler below apex. Secondaries deep smoky, almost black, with pale fringes." - Note: glitranana was synonymized with galaxana which is extremely variable.
