Head, thorax, forewings grey, forewings with markings in brownish grey, viz.: an oblique mark on the costa basally, a 2nd at 1⁄3, connecting a diffuse blotch on the discal cell; another distinct spot at the apex of the discal cell; costal apex, and termen with an interrupted marginal series of black scales. Hindwings and abdomen dark grey. ♀︎ similar but generally more pallid. Antennae of ♂︎ setulose in whorls, setulae longer than segment width. Body length (vertex-wing tip) 8.5-9.5 mm (both sexes).
