Earlier it was considered as a subspecies of Ischnura aurora, distributed from Australia and Pacific Islands.[4] There are strong differences in DNA between the Asian forms of the species and specimens from the Pacific.[4] There is also some morphological differences; dorsal side of segment 8 and 9 are entirely blue in Asian forms compared to only 1/3 of length of segment 8 is blue in specimens from the Pacific.[5] The form found in Indian subcontinent and Iran is Ischnura aurora rubilio Selys, 1876 and is now considered as a good species, Ischnura rubilio.[3]
