About the Discovery
Scientists from the Zoological Survey of India identified two previously unknown spider species during biodiversity surveys conducted in the forest ecosystems of Nagaland. The discovery reflects the ecological richness of Northeast India, which is considered one of the world’s biodiversity hotspots.
The newly discovered spider species belong to unique arachnid groups and were found in dense forest habitats that remain largely unexplored scientifically.
Such discoveries help scientists understand:
- Ecological balance
- Evolutionary biology
- Forest ecosystem health
- Species diversity
- Climate adaptation mechanisms

Newly Discovered Spider Species in Nagaland
The Zoological Survey of India discovered two new spider species named:
- Psechrus ntu
- Psechrus phenshunyu
Both species belong to the Psechrus genus under the family Psechridae, which is known for building large horizontal sheet webs in humid forest habitats. These spiders were named after the villages in Nagaland where they were first discovered — Ntu and Phenshunyu.
The discovery further strengthens Northeast India’s status as a major biodiversity hotspot and highlights the importance of scientific exploration in the region.
