Researchers have made a groundbreaking discovery in the Siang valley, uncovering two new species of rare solitary bees that highlight the rich biodiversity of the Eastern Himalayas and the need to protect the region’s fragile ecosystem. According to officials, the discovery was made by researchers from the Ashoka Trust for Research in Ecology and the Environment (ATREE), Bengaluru, during the recent Siang expedition.
The two newly discovered species, Elaphropoda triangulata and Habropoda adi, have been published in the European Journal of Taxonomy. Elaphropoda triangulata was named after the triangular markings on its abdomen, while Habropoda adi was named in honour of the Adi indigenous community of Arunachal Pradesh. Each species is currently known from only one male specimen, making the discovery significant and emphasizing the need for further surveys to understand their distribution, ecology, and conservation status.
Solitary bees, like these newly discovered species, play a crucial role as pollinators, maintaining healthy ecosystems and supporting agriculture. Unlike honeybees, they do not live in colonies and usually nest alone. However, their survival is threatened by habitat loss, infrastructure development, and other human activities, stressing the need to conserve the forests and natural habitats of the Eastern Himalayas, one of the world’s recognised biodiversity hotspots.
The discovery adds to the growing list of new species being reported from Arunachal, which is known for its rich wildlife and largely unexplored forests. Deputy Chief Minister Chowna Mein welcomed the development, stating that the discovery of the two rare solitary bee species reflects the state’s extraordinary natural wealth and scientific importance.
Mein congratulated the researchers from ATREE on the achievement, emphasizing that such discoveries strengthen Arunachal’s position as a globally significant biodiversity hotspot, deserving sustained conservation efforts. The findings not only highlight the exceptional biodiversity of the Eastern Himalayas but also reinforce the need to conserve the region’s fragile ecosystems.
