( 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.

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.
