Indolestes davenporti[1] is a species of damselfly in the family Lestidae. It is known only from Western Ghats, south of Palakkad Gap.[2]
Fraser described this damselfly in 1930 as Ceylonolestes davenporti.[3] Later it was considered as a subspecies of Indolestes gracilis. Kimmins re-evaluated it as a good species, Indolestes davenporti.[4][1][2]
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.[5]
Female is similar to the male; differs only in the eye color and color of the last segments. Segment 9 is black.[5]
It is found south of the Palakkad Gap, from 4,000 to 6,000 feet in Western Ghats. It is found around grassy edges of ponds, streams and marshes in the hills.[3][5][6]
