Hosts.

Micrurapteryx baranchikovi sp. nov. ( Gracillariidae ).

Distribution.

Republic of Khakassia.

Remarks.

Morphologically, the specimens of Campoplex sp. aff. borealis from Khakassia are very similar to Campoplex borealis from the Western Palearctic (Zetterstedt, 1838) (Andrey I. Khalaim det.), with hind femur dark reddish brown to black, as was already recorded in the specimens from north-west of European Russia (Yu et al. 2016). However, DNA barcoding highlights a significant divergence (i.e., 7.3%) between the Khakassian specimens and C. borealis identified from Germany (Fig. 3, Suppl. material 3: Table S3). Such a divergence may suggest the presence of a cryptic species in Khakassia. To test this hypothesis, a special study, involving more sampling across the distributional range of C. borealis , would be needed.
