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.
