Description. Male unknown. Female. Head ( Fig. 24 ): Black with white tipped scales; length of labial palpus ca. 2 times diameter of compound eye, white laterally, distal part of second and third segment grey, shining purple reflection in front view. Thorax: Notum and tegulae black mixed with a few white scales. Forewing length 5 mm; forewing broadly subtriangular, costa genly arched, apex blunt, termen convex, dorsum straight. Ground colour white, with black scales and dots in basal half, a transverse brown band from costa to dorsum just before middle of wing, apical part of wing irregular coloured black, mixed with shiny brown and lead-grey scales and lines. Fringe black, paler a tornus. Hindwing rounded apically, shiny black brown, paler in basal region, fringe white with a black subbasal line. Abdomen: Genitalia ( Fig. 67 ) with papillae anales moderate, apophyses of equal length; sterigma urn-shaped, sternite 7 square, hind margin concave, somewhat crenelated; lamella antevaginalis spinulose, lateral, with small, sclerotized ridges, ostium with rectangular sclerotization, broader than ductus bursae; ductus bursae slender, colliculum about 1/3 length of ductus; corpus bursae ovoid, membranous and spiculated, signum a strongly scobinate plate.

Distribution. Bhutan.

Etymology. The name brunnofasciana refers to the transverse brown band of the forewing.
