Male: Forewing length ca. 11.5 mm, hindwing length 13.0 mm, body length 12.5 mm; general color dark brown ( Fig. 5 View FIGURE 5 ). Head mostly dark brown except the areas between posterior ocelli to compound eyes are yellow brown. Antennae and palpi brown. Pronotum disc dark brown to black, rugosities present medially, and the smooth longitudinal band among the centerline not striking ( Fig. 6A View FIGURE 6 ). Legs dark brown, femora becoming pale basally; wings hyaline, veins dark brown. Abdomen dark brown and slightly sclerotized. Posterior margin of tergum 10 darkly sclerotized, recessed medially and rearward, extending as a process, with wide lateral grooves on surface, and perpendicular to tergum 10 posteriorly ( Fig. 6B View FIGURE 6 ). Vesicle reduced as a pale spot on posterior margin of sternum 8 ( Fig. 6C View FIGURE 6 ). Paraprocts sclerotized, distally swollen, with a basal sclerotized bar; apex ending with a short papillary cone ( Fig. 7 View FIGURE 7 ). Aedeagus membranous, without conspicuous sclerites; ventrally extending laterally into a pair of ridges with a median round knob; bearing a patch of basal and median ventral spines except the apex ( Figs. 8–9 View FIGURE 8 View FIGURE 9 ).

Female: Forewing length 15.0 mm, hindwing length 14.0 mm, body length 13.5 mm. Body coloration similar to male ( Fig. 10 View FIGURE 10 A–B). Abdomen yellowish, posterior margin of tergum 10 darkly sclerotized and extending as a process similar to male.
