New Damselfly Species Discovered:Euphaea wayanadensis, a new damselfly species, has been identified in the Wayanad region of the Western Ghats, Kerala.
Significance for Kerala & Western Ghats: The discovery brings Kerala’s recorded odonate (damselfly and dragonfly) species count to 191 and the Western Ghats’ total to 223.
Published Research: The findings were published in the journal ENTOMON.
Initial Misidentification: The species was initially mistaken for Euphaea pseudodispar. Detailed study and genetic analysis confirmed its unique identity.
Distinguishing Features: Key morphological differences include a longer black patch on the hind wing, broader humeral and antehumeral stripes in males, and a unique male genital structure.
Habitat Preference:Euphaea wayanadensis thrives in fast-flowing streams with rocky beds and aquatic vegetation within evergreen and semi-evergreen forests.
Restricted Distribution & Vulnerability: The species has a highly restricted distribution, making it vulnerable to habitat loss and climate change. It is active year-round, except during the dry seasons.
Ecological Importance: Damselflies, including Euphaea wayanadensis, serve as indicators of freshwater ecosystem health due to their sensitivity to water pollution.
Discovery Location: First observed in the Kalindi River, Thirunelli, Wayanad, Kerala. Later sightings occurred in Aralam (Kannur, Kerala) and Coorg (Karnataka).
