1. Two New Earthworm Species Unearthed in Tripura

Context: In a remarkable boost to India’s biodiversity records, scientists have discovered two new species of earthworms in the state of Tripura, underscoring the ecological wealth of the Eastern Himalaya–Northeastern Hill region. These species — Kanchuria tripuraensis and Kanchuria priyasankari — are the latest additions to the genus Kanchuria, which is endemic to Northeast India. With these discoveries, the total species count within this genus has now reached 10, and the number of megadrile earthworm species documented in Tripura climbs to 38.

A Glimpse into the Species:

Kanchuria tripuraensis:

• Named after the state of Tripura, this species was found thriving in rubber and pineapple plantations, highlighting the rich soil biodiversity that persists even in agriculturally transformed landscapes. What sets this species apart is its unique anatomical feature — single ventromedian spermathecae located in segments 7 and 8 — a characteristic previously unrecorded in its genus.

Kanchuria priyasankari:

• A heartfelt tribute to Prof. Priyasankar Chaudhuri, a pioneer in earthworm taxonomy whose four decades of research have brought national and international attention to Tripura’s subterranean biodiversity. This species belongs to the turaensis species group and is noted for its comparatively smaller body size and a distinctive spermathecal structure that differentiates it from its close relative, Kanchuria turaensis.

Ecological and Scientific Significance:

• Tripura’s emerging status as a biodiversity hotspot for soil invertebrates is now further strengthened. The discovery of these two species reinforces the importance of microfauna in ecosystem health and the role of earthworms as ecological engineers, improving soil aeration, nutrient recycling, and plant productivity.

Such findings are particularly important at a time when concerns are rising about the impact of tourism and wildlife safaris — such as those in the Kali Tiger Reserve — on sensitive ecosystems. Conservationists argue that greater emphasis should be placed on soil biodiversity conservation, which is often overlooked in mainstream environmental efforts.

India’s Position in Global Earthworm Diversity: 

India is home to over 500 described species of earthworms, many of which remain understudied. The Northeast region, especially the Eastern Himalayan zone, ranks as the second-richest in earthworm diversity in India, after the Western Ghats. These discoveries further highlight the need for comprehensive soil biodiversity assessments, particularly in lesser-explored regions like Tripura.

Final Thoughts: The identification of Kanchuria tripuraensis and Kanchuria priyasankari not only adds new names to taxonomy but also sends a powerful message about the hidden diversity beneath our feet. These discoveries highlight the urgent need to protect below-ground biodiversity, which supports life above the ground — from plants and animals to humans themselves.
