Subspecies

There are three recognized subspecies.[1]

Indolestes gracilis birmanus (Selys, 1891) described from Myanmar is now considered as a distinct species, Indolestes birmanus.[4]

Description and habitat

It is a medium sized damselfly with blue eyes. Its thorax is black on dorsum with a narrow blue mid-dorsal and broad ante-humeral stripes. The lower edge of the black is like a saw-tooth, followed by azure blue on the base of the lateral sides. Wings are transparent with black or dark reddish-brown pterostigma. Abdomen is azure blue on the sides, broadly black on dorsum up to the basal half of segment 9. The apical half of segment 9 and whole of segment 10 are azure blue. There is a black spot on each side of segment 10. Anal appendages are blue; black on old males.[8]

Female is similar to the male; differs only in the eye color and color of the last segments. Segment 9 is black.[8]
