Rare Jumping Spider Recorded in India for First Time

Researchers have documented a rare species of jumping spider in Assam, marking its first recorded presence in India and adding a significant entry to the country’s biodiversity records. The discovery highlights the ecological richness of southern Assam and underlines the scientific importance of its forest ecosystems.

First Indian Record of Colyttus bilineatus

The species, identified as “Colyttus bilineatus”, was recorded by researchers from Assam University, Silchar. The documentation was made at Loharbond in the Inner Line Reserved Forest of Cachar district. This forested area lies close to the borders of Mizoram and Manipur and forms part of a biologically sensitive landscape in the Barak Valley region.

Significance of the Discovery

Jumping spiders belong to the family Salticidae, known for their excellent vision and active hunting behaviour. The recording of “Colyttus bilineatus” in India extends the known geographical range of the species. Such findings are crucial for understanding species distribution patterns and assessing the health of forest habitats in the eastern Himalayan foothills and adjoining regions.

Biodiversity Value of Southern Assam

The Inner Line Reserved Forest, where the spider was found, is characterised by dense vegetation and varied microhabitats. These conditions support diverse insect and arachnid populations, many of which remain poorly studied. The discovery reinforces the role of southern Assam as an important biodiversity zone and a potential hotspot for future zoological research.

Important Facts for Exams

• Jumping spiders belong to the family Salticidae.
• Species range extension is important for biodiversity assessment.
• Reserved forests play a key role in species conservation.
• North-East India is a recognised biodiversity-rich region.

Implications for Research and Conservation

Scientists note that such findings emphasise the need for systematic faunal surveys in lesser-explored forest areas. Continued research can help identify more undocumented species and support evidence-based conservation planning. The record of “Colyttus bilineatus” from Assam strengthens the case for protecting forest habitats that serve as reservoirs of unique and rare fauna.
