SubspeciesEdit
Fraser considered the specimen found in northeast as Aciagrion approximans and in south as Aciargion hisopa race krishna.[6][5] A recent study revealed that the subspecies krishna found in south is not conspecific with A. hisopa and found to be very close to A. approximans found in northeast; but differing at the level of subspecies.[4][3]
