Dodia kononenkoi Tshistjakov & Lafontaine, 1984

( Figs 2I, J , 3A, B )

Dodia kononenkoi Tshistjakov & Lafontaine, 1984: 1553 , figs 5, 6, 9, 12. Holotype ♂ (ZISP). Type locality: USSR, Magadanskaya Oblast’, Bolshoy Annachag Range.

Material examined. Paratype: 1 ♂, [USSR], Magadan Oblast’, Paren’ River , 30.VI.1972, N. Dokuchaev leg. ( FSCEATB) ( Figs 2J , 3A ) . Other material: 1 ♂, Russia, East Yakutia , Tomponsky district , 45 km ENE Razvilka village, 227th km of road R-504 «Kolyma», Suntar-Khayata Range , headwaters of the Vostochnaya Khandyga River, mountain near the mouth of Kyurbelyakh River, rubble scree of the southern slope, 1000–1200 m, 18.VI.1991, A.G. Belik leg. ( ABC) ; 1 ♂, Russia, Zabaykalsky Krai , 22 km SE Udokan village, SW part of part of Udokan Range , upper reaches of Naminga River, scree, 1985 m, 21.VII.1998, A.G. Belik leg. ( ABC) .

Diagnosis. Adults of this species have a uniform brownish-gray coloration of wings and body, almost indistinguishable from that of D. transbaikalensis and D. sikhotensis , but usually darker than theirs ( Figs 2I, J ). In male genitalia, apical processes broad, rounded, equal in size or the lower one larger. Notch between processes narrow, rather deep. Uncus is shorter and broader than in D. transbaikalensis and D. sikhotensis ( Figs 3A, B ). The aedeagus is thickened distally. The vesica is simple, elongated, and usually has two clusters of spicular cornuti at the base and at the apex (see Fig. 9 in Tshistjakov & Lafontaine 1984, and Fig. 12 in Rekelj & Česanek 2009). A male from the Suntar-Khayata Range has two clusters of cornuti near the apex of the vesica ( Fig. 3B ).

Genetic data. COI gene sequences of Dodia kononenkoi specimens from different localities in the boreal zone of Asia and North America are nearly identical (BOLD; Fig. 1 ; Table 2 ).

Distribution. A Holarctic boreal species found in the mountains of the northern part of the Russian Far East (East Yakutia, Magadan Oblast’, Southern Chukotka), Northern Transbaikalye (Barguzin and Udokan Ranges) and Canada (Yukon Territory) ( Tshistjakov & Lafontaine 1984; Tshistjakov 1988; Rekelj & Česanek 2009; Dubatolov 2010; Zahiri et al. 2017; Dubatolov 2023; our study). The indication for the Polar Urals and Norilsk ( Murzin 2003) is probably wrong.

Ecology. Inhabits dry mountain tundra. Flight period from mid-June to the end of July. Larval biology and host plants are unknown.

Notes. The Dodia kononenkoi type series includes specimens from two continents. However, it is inappropriate to distinguish a possible separate North American subspecies, given the high similarity in habitus and genital structure, and the minimal differences in COI gene sequences.

The southern limit of the species distribution in the Russian Far East needs to be clarified. The indication of Dodia kononenkoi for the Myaochan Range from the Gorny village in the Lower Amur Basin ( Dubatolov 2009) ( Fig. 6 ), based on a low-resolution photos of a single female initially identified as « Dodia spec. » and D. albertae in Ivinskis & Saldaitis (2001, 2004), needs further verification.
