Phyllonorycter sp. 5 ( cf. dakekanbae Kumata )

Material examined. Russia: SO, Sakhalin Island, Yuzhno-Sakhalinsk, Gagarin Park , 46.96N, 142.75E, 69 m alt., Betula platyphylla , 11.VII.2017, 1 larva, NK621 , MK 403716 , deposited in INRA.

Leaf mine. The mine is similar to one of Ph. ulmifoliella on Betula platyphylla ( Fig. 12B ). Pupation in the mine.

Trophic specialization. Monophagous on Betula platyphylla (Betulaceae) .

Distribution. Russia: RFE—SO.

Remarks. BIN of unknown species—BOLD: ADM2521. In East Asia, four species of Phyllonorycter develop on Betula : Ph. cavella (Zeller) , Ph. dakekanbae (Kumata) , Ph. ulmifoliella (Hübner) , and Ph. ermani (Kumata) ( De Prins & De Prins 2018) . The first three species are known to colonize Betula platyphylla , the latter species develops only on B. ermanii . The nearest neighbor to Phyllonorycter sp. 5 is Ph. ulmifoliella with a genetic distance 3.0% ( Table 2 ). The other two Betula -feeding species, Ph. cavella and Ph. ermani , are genetically more divergent (>11%) comparing to Phyllonorycter sp. 5 ( Table 2 ). No DNA barcode sequences of Ph. dakekanbae exist in genetic databases. Keeping in mind that it feeds on the same host plant as Phyllonorycter sp. 5, the latter could be Ph. dakekanbae .
