( Figs 7 ¯8)

Material. Holotype: ♂, Russia, S. Siberia, Buryatia Rep., Udunga vill. [51°07′29″ N / 105°57′53″ E], 9¯ 12.vii.2012, leg. S. Didenko ( ZISP) ; paratypes: 2 ♂, same data as holotype (MWM, RYB) ; 1 ♂, Mongolia, Central Aimak, 25 km W Erdennesant , 47°22′ N / 104°13′ E,14¯ 15.v. 2003, 1260 m, leg. A. Saldaitis (MWM).

Description. Male. Length of holotype fore wing 20 mm (paratypes 19¯ 21 mm). Thorax and tegula densely covered with grey scales, tegula and patagium grey. Antenna simple, not pectinate. Fore wing grey, rather wide with rounded apex, with thin reticulated pattern of very thin black undulated lines, thin undulated transverse black bands in postdiscal and submarginal areas, wide black field along costal edge in discal area, blurred brown field at cubital veins in discal area. Hind wing grey with thin reticulated pattern of very thin black undulated lines. Fringe on both wings dark at veins, pale between veins.

Female unknown.

Diagnosis. The subspecies differs from the nominal taxon, distributed in northeastern China, Korea and southeastern Russia, possibly by a smaller size (length of male fore wing of the nominal taxon 21¯ 26 mm), paler colouring, finer undulated pattern on the fore wing, less developed dark area on the costal edge of the fore wing. Etymology. The new subspecies is named after the amateur collector Sergey Didenko (Moscow) who collected the holotype of the new species.
