Thorax (Fig. 11 ). Thorax dark brown with mesodorsal transversal white line. Collar white. Forewing length: 9.5 mm; forewing ground colour dark brown; basal area without marked patches, white scales scattered near dorsum; median discoidal stigma darker coloured, rectangular, basally and distally thinly edged with white; postmedian patch diffuse, white; postmedian line marked on costal half; subterminal line thick, zigzagging, disrupted distally at M1; margin with large white spots; fringes bronze.

Abdomen. Male sternum A8 posterior margin straight.

Male genitalia (N = 1) (Fig. 56 ). Uncus broad with straight lateral margin, apex truncate, medially slightly incurved. Gnathos reduced to thin band without posterior projection. Valva ventral margin bent dorsad on distal half, dorsal margin slightly convex, apex pointed. Juxta elongated, with base rounded, medially narrowing, apex blunt. Saccus small, pointing dorsad.

Female genitalia Not known.

Distribution.

Known from Mount Susu (975 m) in the Morobe Province (Papua New Guinea).

Phylogenetic relationships.
