Micrurapteryx gradatella ( Herrich-Schäffer, 1855)

( Fig. 10C )

Material examined. Russia: AO, Skovorodino , nearby the train station, 53.98N, 123.93E, 431 m alt., Vicia sp., 26. VI .2016, 1 larva, NK589, MK 403682 , deposited in INRA.

Leaf mine. Mine is similar to M. caraganella , but often is smaller as host plant leaves are generally small ( Fig. 10C ). The preceding tunnel on the lower side of the leaflet ( Fig. 10C ) can be much longer than that of M. caraganella . Pupation is on the leaf surface, in a cocoon similar to M. caraganella .

Trophic specialization. Oligophagous on Fabaceae : Lathyrus spp., Vicia amoena , V. sepium (Kirichenko et al. 2016; De Prins & De Prins 2018).

Distribution. Russia: RFE—AO (Baryshnikova 2016); Europe ( De Prins & De Prins 2018).

Remarks: Earlier records in literature mentioning Micrurapteryx gradatella on Caragana arborescens ( Dovnar-Zapol’skiy 1969; Dovnar-Zapol’skiy & Tomilova 1978; Kuznetsov & Baryshnikova 1998; Kuznetzov 1981; Noreika 1997; Baryshnikova 2016) to be attributed to M. caraganella (Kirichenko et al. 2016) .
