Melanoneura bilineata[2][1] is damselfly in the family Platycnemididae. It is endemic to Western Ghats in India, restricted to Kodagu and Wayanad districts.[1][3]
It is a medium-sized damselfly with black-capped blue eyes. Its thorax is black, marked with a narrow ante-humeral azure blue stripe and two broad blue stripes on the sides. Its abdomen is black, marked with azure blue broadly on the sides of the segments 1 and 2. Segments 3 to 6 are marked with tiny basal annules. Segments 8 to 10 are blue, marked with very narrow basal black rings. Female is similar to the male; but only matured adult has the blue marks. Others are marked with yellow or bluish-green.[4]
It is similar to Caconeura ramburi; but can be distinguished by the absence of blue basal annules which is very broadly visible in C. ramburi.[4]
It is known only from upper catchments of Kaveri river in Kodagu and western slopes of Wayanad. It is restricted to hill streams with good forest cover.[4][5][6][7][8]
