Two ocelli large, ovoid and protruding (0.45 × 0.40 mm); vertex brown with small ridges in rays around upper apex of eyes and extending onto ocellar tubercles; interocellar space only slightly concave, brown, with three small round indentations at points of an equilateral triangle. Posterior frons concave, brown grading into waxy beige, with horizontal corrugations; anterior portion of frons bulbous and waxy beige; waxy beige smooth anteclypeus. See Fig. 93d. Pronotum. Pronotum large, translucent waxy beige; dorsal surface of pronotum with short orange-brown setae that are thicker and longer laterally; pronotal pattern orange-brown “panther face”, with little discernible detail; no aura.

Legs and body light brown; some specimens with brown maculations laterally on each sternite; subgenital plate orange-brown; asymmetrical with rounded apices. See Fig. 93b. Forewings. Wings extended well beyond abdominal apex (~35% of wing length); blotchy orange-brown to medium brown; surface opaque and matte. See Fig. 93a. Genitalia. Right dorsal phallomere composed of lightly sclerotized bulbous hook-shaped lobe, articulated with right ventral phallomere on lateral side; central field lightly sclerotized with deep open rectangular area posterior-medially; medial margin more heavily sclerotized, with short toothed region at posterior end, and prominent flat spine adjacent, remainder of margin uneven. Small central sclerite with uneven margins nearly flat and finely punctate; anterior end bent posteriorly, shagreened with uneven toothed edge; right ventral phallomere extends from articulation to form smooth rounded structure, punctate, corrugated and narrowed anteriorly; attached anteriorly is mildly dorsally projecting flanged concave punctate arm that extends beyond depth of posterior portion of phallomere. Genital hook with moderate extension to rounded head with moderate hook; arm delicate with distinct bend. See Fig. 94.
