Trichopteryx carpinata (Borkhausen)

( Fig. 26 )

Trichopteryx carpinata : Beljaev & Mironov 2019: 257 (Sakhalin).

Material examined. 1 ♀, Novoaleksandrovsk, 12.V.2011; 1 ♂, Leonidovo, 12.VI.2017.

Distribution. Russia (S RFE: S and central Sakhalin, S Khabarovskii Krai, S Amurskaya Oblast, Primorskii Krai; S and W Siberia, Urals, European Part, N Caucasus), N China (Gansu), Mongolia, northern Kazakhstan,? Turkey, Europe.

Remarks. The finding of T. carpinata in Sakhalin significantly expands its distribution range to the east. Its larvae are polyphagous on deciduous trees, mainly on the various Betulaceae ( Alnus , Betula , Carpinus ) and Salicaceae ( Populus , Salix ).

Externally and in the genitalia shape, T. carpinata is similar to T. ignorata Inoue. Both species have never been compared in literature and can be easily confused superficially. Since T. carpinata is found in Sakhalin and T. ignorata is known from neighbouring Hokkaido, a key to these species may be useful in distinguishing between them, as their ranges may overlap on these islands. The European moths of T. carpinata and their genitalia, which well conform to the East Asian ones, can be seen in Hausmann & Viidalepp (2012, fig. 268), and on the sites Lepiforum e.V. ( Schön et al. 2023) and Mothdissection.co.uk ( Wheeler et al. 2023). The characters of T. ignorata are compiled based on Yazaki (1978, figs 7, 8, 11), Nakajima & Yazaki (2011, figs 1-051-28, 29), Hashimoto (2021: 61, figs 61A–B, 68), and the site Jpmoth ( Niwakagamania et al. 2021).
