Template:Italic title Template:Speciesbox Aciagrion approximans,[1] Indian violet dartlet,[2] is a species of damselfly in the family Coenagrionidae. It is found in east[3][4] and south[5][2][4] of India. The range extends to Thailand, China and Cambodia.[5][2][4]
Subspecies
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][2]
