Dorytomus chinensis Faust, 1883

MATERIAL. Russia: Primorsky Krai, Kaimanovka Vill., 43°38′39″ N; 132°15′59″ E, in litter under Populus tremula , 14.X 2023, 1 ♂.

HOST PLANTS. This is the first record of Dorytomus chinensis from a host. Its closest ally is D. roelofsi Faust, 1883 , which was collected in numbers by the first author in Khabarovsk City and Khabarovsky Krai on a narrow-leaved Salix sp. and is reported as developing on Salix spp. in Japan ( Morimoto & Enda, 1962). It is thus not unlikely that the only found specimen of D. chinensis was only hibernating in litter under the aspen tree, and is associated actually with some Salix sp. growing nearby. The two females from Suwon City in South Korea ( Hong et al., 2000) are unlikely to have been collected from aspen which is not common in the area whereas willows are rather common there.

DISTRIBUTION. Russia (new country record): Far East (southern Primorsky Krai); North-Eastern China, South Korea ( Hong et al., 2000). The species was included in the key to Dorytomus species from the Russian Far East with a note that it was known only from North-Eastern China ( Korotyaev, 1996), and we have seen no material from Russia since then, so the records from Primorsky Krai ( Legalov, 2010; 2020) have not been verified.
