Phyllonorycter sp. 3 ( cf. sorbicola Kumata)

Material examined. Russia: AO, Skovorodino, nearby the train station, 53.98N, 123.93E, 431 m alt., Prunus padus, 26. VI .2016, 1 larva, NK566, MK 403696, deposited in INRA.

Leaf mine. The mine is a white elongated contracted blotch, with up to five folds on epidermis-covering mine, along the main vein. Pupation in the mine.

Trophic specialization. Monophagous on Prunus padus (Rosaceae) .

Distribution. Russia: RFE—AO.

Remarks. BIN of unknown species—BOLD: ACY3732. In East Asia, only three Phyllonorycter species are known to develop on Prunus: Ph. cerasicolella (Herrich-Schäffer), Ph. ringoniella (Matsumura) and Ph. sorbicola (Kumata) (De Prins & De Prins 2018) . Additionally, Phyllonorycter laurocerasi Kuznetzov also develops on Prunus, but is known only from Georgia (Kuznetzov 1979b) and from the West Caucasian region of Russia (Baryshnikova 2008). Our DNA barcoded specimen of Phyllonorycter does not match any of these three species in BOLD. No DNA barcode of Ph. laurocerasi exists in BOLD. The nearest neighbor is Ph. sorbicola, with minimal genetic distance of 2% but with different BIN (Table 2). The other two species are distant from Ph. ringoniella (7.9%) and Ph. cerasicolella (10.2%) (Table 2). Phyllonorycter sp. 3 represents a novel BIN in BOLD closely related to Ph. sorbicola .
