Fly species resembling a bamboo stalk discovered in Western Ghats

In a significant scientific breakthrough, researchers have discovered a new species of damselfly in the Western Ghats of Kerala.
The species, named “Agasthyamalai Bambootail” (Melanoneura agasthyamalaica), was discovered in Manjadininnavila, Thiruvananthapuram district, near the Peppara Wildlife Sanctuary.
The discovery was made by a team of scientists from MIT World Peace University, Pune, Christ College, Kerala, and the Society for Odonate Studies. Lead researcher Vivek Chandran explained that the species’ name honours the Agasthyamalai landscape where it was found.
The Agasthyamalai Bambootail is only the second known species in the Melanoneura genus, joining the Malabar Bambootail (Melanoneura bilineata) found in the Coorg-Wayanad region.

It is characterised by a long cylindrical abdomen resembling a bamboo stalk, which inspired its common name.
Genetic analysis revealed over seven per cent variation in the mitochondrial cytochrome oxidase-I gene between the new species and its closest relative. The Agasthyamalai Bambootail is distinguished by its long black body with brilliant blue markings and unique structural features.
Interestingly, the species was first observed in streams flowing through home yards into the Karamana River, outside the reserved forest area. This finding highlights the importance of non-protected ecosystems in biodiversity conservation.
The damselfly has also been recorded in Ponmudi Hills and Bonacaud within the Agasthyamalai landscape.
Vivek Chandran emphasised the need for urgent conservation efforts in the Western Ghats, a recognised biodiversity hotspot, given the species’ restricted range.
Dr. Pankaj Koparde from MIT World Peace University stressed the importance of extending conservation efforts beyond protected forest boundaries.
