Asik SyedA fascinating addition to India’s rich biodiversity has emerged from the lush landscapes of Kerala. Scientists have officially identified a new species of damselfly — Euphaea wayanadensis, named after the Wayanad region where it was first observed. This discovery enriches the odonate diversity of the Western Ghats, raising Kerala’s species count to 191 and the total for the Western Ghats to 223.
Taxonomic Classification and Discovery Journey
Belonging to the Euphaeidae family, Euphaea wayanadensis was first spotted in 2013, fluttering near the Kalindi River in Wayanad. Initially mistaken for Euphaea pseudodispar, the insect underwent extensive examination over the years. Thanks to detailed morphological comparisons and genetic analysis, researchers were finally able to confirm its unique identity.
What Sets It Apart?
This species showcases a blend of subtle but striking features:
- A longer black patch on its hind wings compared to its close relatives.
- Males feature broader and continuous body stripes, offering a key identification clue.
- The structure of the male genital vesicle presents distinct traits, playing a crucial role in differentiating it from other Euphaea species.
Natural Habitat and Behavior
Euphaea wayanadensis favors clear, fast-moving streams with rocky beds and rich aquatic vegetation. It thrives in the evergreen and semi-evergreen forests along stream banks in Wayanad and nearby regions. The species remains active throughout the year, barring the drier months of March and April.
However, its limited range and dependence on pristine freshwater ecosystems make it vulnerable to habitat degradation and climate change — a concern that adds urgency to conservation efforts in the Western Ghats.
