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][3]

Description and habitat

It is a small, slim, slender damselfly with violet and black colors. Its thorax is black with lateral violet stripes. Segments 2 to 7 of the abdomen are black on dorsum and violet in the ventral half. Segments 8 and 9 are violet without any marks. Segment 10 is black on dorsum. The lower half of segment 8 is marked with black in A. a. krishna. Female is similar to the male; but paler in colors. Segments 8 and 9 are black and 10 is blue on dorsum.[5][4]

It breeds in ponds, lakes or in slow moving streams.[5][4]
