but otherwise cannot be reliably separated from the other species of the complex by external characters. The male genitalia are characterized in particular by the distally widened valva with a moderately long, pointed dorsal process, a character which is only shared with

Head with dark grey-brown vertex, mottled with white, frons cream-white; first segment of labial palpus dark brown, second segment cream-white on inner and upper surface, ventral and outer surface predominantly dark brown, dark brown mixed with few whitish scales on segment three; antenna black, weakly ringed paler. Thorax and tegula dark brown anteriorly, posterior half mixed cream with dark brown and some rusty brown mottling. Abdomen grey to whitish grey on ventral surface. Forewing dark brown, mottled with greyish white on dorsal margin; white transverse fascia from fold to costa at one-fifth; white medial spot occasionally extended towards costal and dorsal margin; white costal and tornal spots separate; fringes basally dark brown, distal part paler. Hindwing light grey.
