Dodia diaphana arctica Tshistjakov, 1988

( Figs 2B , 3 J )

Dodia diaphana arctica Tshistjakov, 1988: 641 , fig. 7. Holotype ♂ (ZISP). Type locality: [USSR], Magadan Oblast’ , 18 km N Kulu, 800 m.

Material examined. Paratypes: 3 ♂, [USSR], Magadan Oblast’, 18 km from Kulu, upper Kolyma Basin , larch bog, 600 m, 11.VII.1980, Kononenko leg. ( FSCEATB) ; 1 ♂, same data, but altitude 800 m and date 13.VII.1980 ( FSCEATB) . Other material: 1 ♂, [USSR], Magadan Oblast’ , research station «Aborigen», 15.VII.1982, Kononenko leg. ( FSCEATB) .

Diagnosis. The original description states that the moths are distinguished from the nominate subspecies by «more intense dusting of dark, almost black scales and relatively narrow, almost twice as long as wide, forewings» ( Tshistjakov 1988). In fact, the expression of these features in Magadan specimens varies greatly. Some moths are indistinguishable in coloration and forewing shape from those collected from different localities in Siberia and the southern Far East ( Figs 2A, B, C ). Compared to the nominate subspecies, the apical part of the valva is narrower, and the processes are longer and narrower and almost equal in size. Ventral diverticulum of the vesica with 5–6 small spines ( Fig. 3J ).

Distribution. This subspecies is known from a few localities in the Magadan Oblast’ ( Russia), where it is rare ( Tshistjakov 1988; Rekelj & Česanek 2009).

Notes. The FSCEATB collection has four paratypes of this taxon from the vicinity of Kulu, and they are without type labels. I have provided these specimens with red labels with the text « PARATYPUS ♂ / Dodia diaphana arctica Tshistjakov, 1988 / E.S. Koshkin des., 2024» .

The status of this taxon needs to be clarified. BOLD has a COI sequence of a specimen of D. d. arctica from the Magadan Oblast’ (BOLD sequence ID TIPSY574-12), which differs greatly from specimens from the mountains of Southern Siberia and the south of the Far East (7% p-distance). If this is not a mistake and further molecular genetic studies confirm these differences, this should indicate the species status of D. d. arctica Tshistjakov, 1988.
