Xyrosaris spp. , adults, variability of colouration and wing pattern. 21 A–F, Xyrosaris lichneuta ; 22 A–I, X. melanopsamma . Scale bar 1 mm. Distribution . Russian Far East (Khabarovskii Krai, Primorskii Krai, Sakhalin and Kunashir Islands); South Korea ; Northern, Eastern and Central China ( Hebei , Jiangsu , Henan and Hubei ); Japan ( Hokkaido , Honshu, Shikoku, Kyushu); North–East India ( Assam ). Host plants. Confirmed data are absent. Remarks. Until recently, only two species, X. lirinopa and X. lichneuta , had been recorded in East Asia , but all specimens collected in the area were associated with the last species only. Despite the fact that all collected specimens possess high variability in colouration and wing pattern, the identification of them was made mainly by appearance. Thus, the sample from South Korea identified as X. lichneuta and posted to the Genbank (NCBI) was found to be conspecific with X. insularis based on genetic data ( Ponomarenko & Beljaev 2023 ). Moreover, both mentioned species are well differing by male and female genitalia. Therefore, data on the distribution of northeast Indian species X. lichneuta in Eastern Asia as well as its host plants require verification and clarification.
