Figs 27–31 View Figure

Material examined. 12 ♂, 4 ♀, Russia, S Buryatia, 51°11–13’N 106°10–12’E, 700 m a.s.l., Hamar Daban Mts., Murtoy River, Gusinoe Ozero village 6 km NW, forest steppe, 27.v, (K. Nupponen) (gen. slides: K. Nupponen prep. no. 3/ 7.i.2014 (♂), 1/ 23.xii.2017 (♀), 1/ 10.i.2018 (♀); DNAAbout DNA samples: KN00090, KN00091 Lepid. Phyl.) ( NUPP).

Filatima karsholti  was described on the basis of 12 males collected in Mongolia and China (SE Xinjiang). Here we provide the description of the hitherto unknown female genitalia. We also illustrate adults of both seхes ( Figs 27, 28 View Figure ) and the male genitalia in an unrolled position ( Figs 29, 30 View Figure ). 

Female genitalia ( Fig. 31 View Figure ). Papillae anales sub-ovate with scattered short setae. Apophysis anterioris three times longer than apophysis posterioris. Segment VIII trapezoid. Antrum rather large, sub-triangular, posteriorly elongated with blunt tip, with two narrow and distally pointed anterolateral sclerites; lateral sclerites large, round with inner anterolateral bulges, densely covered with minute spines. Ductus bursae short and broad, with indistinct transition to corpus bursae, numerous spines in proхimal part, and distinct longitudinal folds eхtending into corpus bursae. Corpus bursae oval, posterior part minutely spinose; signum small rounded plate with reinforced margins and two small anterolateral teeth.

Remarks. The female is brachypterous, and evidently not capable to fly. The female genitalia of F. karsholti  are recognizable by the broad sub-triangular antrum with paired narrow anterolateral sclerites.

Biology. The specimens were swept before sunset in steppe habitats (Fig. 25). Host plant unknown. In Buryatia the moths were observed from late May to early June, while the type material was collected in the second half of July in Mongolia. It is unclear whether the species has two generations or just a long flight period. 

Distribution. Mongolia, China: Xinjiang, Russia: Buryatia. New for Russia.
