Male. Measurements. Holotype TL = 18.3 mm, GW = 8.1 mm, PW = 5.84 mm, PL = 4.20 mm, TL/GW = 2.26, PL/PW = 0.72. EW = 0.25 mm; OW = 0.30 mm. No notable difference in size among paratypes. Head. Two ocelli large, ovoid and protruding (0.40 × 0.30 mm); vertex dark brown with small ridges in rays around upper apex of eyes and extending onto ocellar tubercles; interocellar space concave, dark brown, with two small round indentations. Frons waxy white with brown edges near ocelli; posterior concave with occasional long setae; bound on either side by ridges extending from inner apex of ocelli outwards to lateral edges of clypeus. Anterior portion of frons bulbous and waxy white; clypeal suture with two proximal setae, demarcates waxy white smooth anteclypeus. See Fig. 15d. Pronotum. Pronotum average in size for genus; translucent waxy beige; variable length orange-brown setae along anterior margin; setae on dorsal surface of pronotum thicker and longer laterally; pronotal pattern dark orange-brown “panther face”, not impressed, detail discernible; small lateral and anterior aura. See Fig. 15c. Body. Wing brace present. Legs and body light brown; one specimen with brown maculations laterally on each sternite; subgenital plate light brown with rounded apices. See Fig. 15b. Forewings. Wings extended well beyond abdominal apex (~35% of wing length); blotchy medium to dark brown; surface matte and opaque. See Fig. 15a. Genitalia. Right dorsal phallomere composed of lightly sclerotized, unusually curved, bulbous hook-shaped lobe, articulated with right ventral phallomere on lateral side; medial side of lobe deeply emarginated from medial edge of remainder of phallomere; central field shallow, cupped, lightly sclerotized; medial margin more heavily sclerotized, smooth, with long posterior projecting spine and two medially projecting spines located on anterior third of medial margin. Small central sclerite concave, punctate, with large shagreened medially projecting wide upside down V-shape on ventral edge, point of which extends into small spine; right ventral phallomere extends from articulation to form shagreened rounded structure, with prominent medially projecting spine located posteriorly; attached anteriorly is flanged punctate concave arm that extends slightly beyond depth of rest of phallomere, edge shagreened. Folded anterior portion of left phallomere dramatically modified with sclerotized anterior wall and posteriorly projecting smooth spine located ventrally. Genital hook with short extension to pointed head with short hook. See Fig. 16.
