(Fig. 10G)

Material examined. Russia: SO, Sakhalin Island, Yuzhno-Sakhalinsk, Gagarin Park, 46.96N, 142.75E, 69 m alt., Acer pictum, 11.VII.2017, 1 larva, NK624, MK 403704, deposited in INRA.

Leaf mine. The mine and the leaf rolls are similar to those of C. acericola and C. gloriosa, however the mine of C. heringi is smaller and the folded leaf margin stage is often missing (instead larvae make a cone from the leaf tip right after vacating mine) (Fig. 10G).

Trophic specialization. Monophagous on Acer pictum (Sapindaceae) (Kumata 1966).
