Diagnosis. Wingspan 20.0–26.0 mm. This species is closely related to Nephelobotys brevis sp. nov., similar in both appearance and genitalia, but can be distinguished from it by the much thinner setae of uncus, the outside sella with dorsal process nearly the same length as the ventral process, the ventral process not extending beyond the ventral margin of the inside sella in the male genitalia ( Fig. 18 ), and by the shallowly funnel-shaped antrum with posteroventral margin shallowly U-shaped and well sclerotized, surrounded by sinuated lamella antevaginalis ( Fig. 25 ).
