Exaeretia lepidella (Christoph, 1872)

Material examined. RUSSIA: ALTAI REPUBLIC: Aktash vill., 50°19′12″N, 87°36′00″E, grassy steppe, rocks, 1400 m, 21.vi.2015, 3 ƋƋ, 24.vi.2019, 4 ƋƋ, J. Šumpich leg. ( NMPC);Aktash env., road to 9. station (below “Zavod“), 50°19′14″N, 87°42′57″E, mountain meadows, 2260 m, 22.–23.vi.2015, 1 Ƌ (gen.slide DEEUR 6172 P. Buchner), (Barcode TLMF Lep 23282), J. Šumpich leg. ( NMPC); Kosh-Agach Distr., Kurai env. (15 km SW), Dzhangyskol lake, 50°10′49″N, 87°44′19″E, coniferous forest/steppe, 1830 m, 24.–25.vi.2015, 1 Ƌ, J. Šumpich leg. ( NMPC); Kosh-Agach Distr., Kurai env. (6.5 km SW), 50°10′35″N, 87°53′55″E, grassy steppe, 1550 m, 9.–10.vii.2014, 1 Ƌ, J. Šumpich leg. ( NMPC); Kosh-Agach Distr., Kurai env.(15 km SW), Dzhangyskol lake, 50°10′49″N, 87°44′19″E, steppe, 1830 m, 7 ƋƋ, J. Šumpich leg.( NMPC).

Molecular data. BIN BOLD: ACX7885 (n = 5, 1 public, 2 from Altai). E. lepidella and E. nebulosella (Caradja, 1920) are not distinguishable in their barcodes, and therefore BOLD generated only one BIN for both taxa. However, the two species differ highly in habitus. The average intraspecific divergence of the barcode regions of both taxa is 0.27% (maximum 0.48%).

Distribution. Russia, Kazakhstan, Mongolia ( LVOVSKY 2013).

Exaeretia lvovskyi Buchner, Junnilainen & Nupponen, 2019

Material examined. RUSSIA: ALTAI REPUBLIC: Aktash vill., 50°19′12″N, 87°36′00″E, grassy steppe, rocks, 1400 m, 24.vi.2019, 1 Ƌ, J. Šumpich leg. ( NMPC); Chulyshman valley, 45 km N of Ulagan vill., 51°01′03″N, 88°00′39″E, grassy steppe, rocks, 600 m, 26.–27.vi.2019, 1 Ƌ, J. Šumpich leg.( NMPC); Kosh-Agach Distr., Chagan-Uzun env., Krasnaya Gorka hill, 50°05′00″N, 88°25′15″E, rocky steppe, 1870 m, 1.–3.vii.2019, 11 ƋƋ 2 ♀♀, J. Šumpich leg. ( NMPC).

Molecular data. BIN BOLD: ADC5991 (n = 6; 3 public, 4 from Altai). The average intraspecific divergence of the barcode region is 0.19% (maximum 0.32%).

Distribution. Russia (Southern Ural, Altai Mts., Buryatia) ( BUCHNER et al. 2019).

Remark. The species description is partly based on the specimens collected in the Altai Mts. by the second author in 2015.
