Caconeura ramburi[2][1] is a damselfly species in the family Platycnemididae. It is commonly known as the Coorg Bambootail[3] or Indian blue bambootail.[4] It is endemic to the Western Ghats.[1][5]
It is a medium-sized damselfly with black-capped blue eyes. Its thorax is black on dorsum and azure blue on the sides. There is a very narrow azure blue antehumeral stripe and a narrow black stripe on the postero-lateral suture on each side. Wings are transparent with black, diamond shaped pterostigma. Abdomen is black with azure blue stripes on segment 1 and 2. Segment 3 to 7 have broad basal rings in azure blue. Segments 8 to 10 are azure blue on dorsum, with black basal annules. The lateral side of segment 10 is black. Female is similar to the male; but the markings more greenish-blue or even yellow, except in very old specimens.[6]
It is larger and more slender insect than Caconeura gomphoides and breeding at a lower altitude. The broad blue basal annules will help to distinguish it. The larger size, differently shaped pterostigma, the absence of a ventral spine on the base of the superior appendages, and the underside of the head entirely black, will help to distinguish it from Caconeura risi.[6]
It breeds in forest streams. Commonly found perched on riparian vegetation along shaded streams.[6][7][8][3][4]
