New to Thailand. All previous records from Thailand as this species are considered to be Chilades putli. The first reliable record from Thailand is obtained a male specimen by Mr.Supat Sophonviwatkul on 14.Apr.2014 in Sa Kaeo dist., E.Thailand. The butterfly is very localized species and found in fields at low elevations.
No records from Laos have been confirmed and confirmation by reliable specimens is necessary in the future.
