Type material. Holotype— ♂, Rwanda, Butare, beginning 2014, leg. V. Popoudina ( SZMN).

Description. Forewing length 13.5 mm; forewings light brown speckled by darker scales; other pattern is reduced and consists of one costal antemedial spot, wide diffuse discal spot, apical line directed towards vein M1, and a series of marginal internervular spots; hindwings light brown with three submarginal and one small discal spots. Male genitalia ( Figs. 7–8 ): uncus long and narrow, slightly curved, with large bulbous dorsal projection; valves consisting of wide base and two narrow processes, basal is very short and directed upwards, rounded at apex, apical one is four times longer and straight; juxta broad, saccus triangular, aedeagus straight, with small spines on apex, vesica bag-like, with three separate apical portions, two of them covered with small granulation.

Remarks. The new species differs from the nominotypical one by the bulbous dorsal process on tegumen; short (four time shorter than apical process) and straight basal processes on valves, straight apical valve processes. By the wing pattern, the new species is characterized by reduction of a dark pattern on the forewings without any transversal bands.

Etymology. the species is named after Mrs. А. Popoudina (Novosibirsk, Russia) who collected the new species.
