(adults Fig. 19C; male gen. Figs. 39G–39L)

Cleta jacutica: Viidalepp, 1996: 49; Gordeeva & Gordeev, 2007: 122; Mironov et al., 2008: 206; Beljaev & Mironov, 2019: 276.

Material examined. Buryatia: Samarta, 18.VII.2019, 5 ♁ (GenBank ID: OK073236), I. Makhov; Mondy, 2000 m.a.s.l., 14.VII.1965, 1 spm., Gorodkov [ZIN]; Taloy, 18.VII.2007, 2 ♁, T. Gordeeva [IGEB] . Republic of Sakha (Yakutia): Momsky District, Chersky Range, env. of Khonuu, tuberculosis dispensary, 6.VII.2013, 1 ♁ (GenBank ID: MZ148325), S. Nogovitsyna [ISEA].

Distribution. East Siberian, boreomontane. Republic of Buryatia, E and S Yakutia, Magadanskaya Oblast, Kamchatka. Outside Russia in N Mongolia.

Hostplants: unknown.

Genetic note. Appealingly, the species is genetically heterogeneous. We previously assumed that there was the mitochondrial introgression between C. jacutica and C. perpusillaria (Makhov & Lukhtanov 2021) . However, it cannot be ruled out that this pair of taxa is a single widespread species with two or several deeply diverged haplogroups. The study of additional nuclear markers is required.
