Remarks. Euscrobipalpa chitensis was described from a single male ( Fig. 22) collected in the environs of Kyra village, Zabaikalskiy krai, Russia. The species is very similar to S. bidzilyai (for the differences see under that species). Here we describe the female genitalia of S. chitensis for the first time.

Female genitalia ( Figs132,133). Papillae anales subovate,covered with long setae at base; apophyses posteriores 4 times as long as apophyses anteriores; segment VIII about as broad as long, sternum VIII densely covered with microspines, subgenital plates 1/3 width of sternum VIII, parallel-sided, lobes of ventromedial depression broad, rounded and separated by triangular incision anteromedially, not extending beyond anterior margin of sternum VIII; apophyses anteriores as long as segment VIII and 2–2.5 times length of ductus bursae; ductus bursae moderately broad, of even width except narrowed posterior portion; corpus bursae rounded, 1/3 length of ductus bursae; signum with large, subtriangular basal plate and straight or weakly curved acute process directed anteriorly.

Molecular data. BIN: BOLD:AEC6928. The intraspecific average distance of the barcode region is 0 % (n=4). The minimum distance to the nearest neighbour, S. bidzilyai ( Povolný, 2001) (BIN: BOLD:AEC6545), is 3.04% (p-dist) ( Fig. 3).

Distribution. Russia: Buryatia (new record), Zabaikalskiy kraі ( Povolný 2001: 188); China: Shaanxi, Ningxia ( Li & Bidzilya 2019: 122).
