It is a medium sized dragonfly with bottle-green eyes. Its thorax is dark metallic-blue, marked with citron-yellow. There is a narrow mid-dorsal carina, a humeral spot and a narrow stripe on mesepimeron. Abdomen is black, marked with citron-yellow. Segment 1 has a triangular spot on mid-dorsum. Ssegment 2 has a small diamond-shaped spot on mid-dorsum. Segment 3 has its base dorsally and sub-dorsally narrow yellow and a stellate spot on mid-dorsum. Segments 4 to 9 are similar to 3; but the lateral spots much smaller. Segment 10 is entirely black. Anal appendages are black. Female is similar to the male.[6]
