About Mortonagrion santha:
- It is a new species of damselfly.
- It was discovered around a small farm pond surrounded by a coconut plantation in Dasarathpur, Rangat tehsil, in the Andaman and Nicobar Islands.
- It belongs to a genus of insects known for their incredible secrecy, often blending perfectly into the shaded coastal vegetation.
- The Mortonagrion santha’s physical distinct features separate it from its closest known relative, Mortonagrion arthuri, a species found further east in Southeast Asia.
- The new damselfly has unique pale-blue, crescent-shaped postocular spots located just behind its eyes.
- It also has a distinctive bright-blue splash of colour on its ninth abdominal segment.
- Under a microscope, M. santha also shows a uniquely shaped, three-lobed collar area (the prothorax) and different proportions in its tail-like mating appendages, where the upper parts are only about half the length of the lower parts.
