Thorax: Dorsum mostly naked, dark fuscous, sparsely covered with slender brownish scales. Forewings light brown to stramineous, heavily mottled with various shades of fuscous; basal two-thirds of wing dull white to stramineous, with 3 or 4 rather indistinct fuscous spots along costal cell; a large, slightly curved fuscous spot extending between M2 and CuA1; two triangular fuscous spots situated along hind margin at CuAl and CuA2; a series of smaller, transverse spots scattered over posterior half of wing; a few broad, silvery white scales scattered somewhat randomly over basal two-thirds though concentrated along major veins; outer third of wing whitish, with numerous irregular spots of light brown; a series of mostly confluent spots bordering apex and termen. Hindwings considerably paler; basal two-thirds light grayish brown; outer third whitish with a nearly continuous, broad row of light grayish brown spots bordering outer margin from apex to CuA1.

Male genitalia: Gnathos a slender, uncinate process arising between socii and projecting ventrally. Valvae with a small, slender, bilateral pair of clavate lobes arising from base of sacculus and nearly contiguous along midline. Lateroposterior lobes of anellus bilaterally symmetrical, deeply forked near base, giving rise to two elongate, asymmetrical processes; inner branch more stout, roughly serrated along entire length of outer (lateral) edge. Parameres greatly lengthened, surpassing apex of uncus, densely pubescent over ventral half.
