Indian Scientists Describe New Legless Amphibian Gegeneophis chandgadi from Maharashtra Backyard

Scientists have described a new species of legless amphibian from a village backyard in Maharashtra, adding a fresh branch to the family tree of caecilians, the burrowing amphibians that most people never see. The species, Gegeneophis chandgadi, was formally named in a multi-institutional study led by the Zoological Survey of India, and it was found not in a remote forest sanctuary but beneath wood piles and damp leaf litter close to human homes in Buzawade village.

Caecilians are limbless amphibians in the order Gymnophiona, adapted for a life spent largely underground. They have elongated, cylindrical bodies, reduced or absent external limbs, and eyes that are often small and may be covered by skin or bone. They live in moist soil, leaf litter, or near streams in tropical regions, which is why they are so easily overlooked. In India, most caecilians occur in the Western Ghats, a biodiversity hotspot that runs down the western side of the peninsula.

The new species belongs to the genus Gegeneophis, a group of Indian caecilians known from the Western Ghats. According to reports, the discovery raises the total count of Gegeneophis species in India to 12, with 11 of them endemic strictly to the Western Ghats. India currently records 41 caecilian species among its 458 total amphibian species.

The animal was first encountered during field surveys in August 2025 in Buzawade village, in the Chandgad region of the northern Western Ghats. Researchers found it beneath wood piles and damp leaf litter very close to human homes, and local residents told them the creatures are quite common locally, frequently unearthed by domestic chickens that eat the younger, smaller ones. The formal description followed in the Records of the Zoological Survey of India on September 2, 2026.

Key Facts

The Hindu reported on September 12, 2026, that scientists had discovered the new subterranean, legless amphibian from Maharashtra. The species was named Gegeneophis chandgadi, and the paper describing it was published under the title Exploring cryptic diversity in Gegeneophis Peters (Amphibia: Gymnophiona: Grandisoniidae) with a novel species from the northern Western Ghats, Maharashtra, India. The paper states that the taxon does not fit the descriptions of any known species.

The Hindu also reported that the discovery was made by a multi-institutional team from the Zoological Survey of India WRC Pune, Yashwantrao Chavan Mahavidyalaya Halkarni, Savitribai Phule Pune University, and the Mhadei Research Centre in Goa. The authors are Sahil Shikalgar, Rahul N. Patil, Pranjal Adhav, Nirmal U. Kulkarni, N. C. Hirgond, N. P. Gramapurohit, Basudev Tripathy, and K. P. Dinesh.

IBG News reported on September 12, 2026, that the species was formally published in the Records of the Zoological Survey of India on September 2, 2026, and that it was subsequently listed by Amphibian Species of the World, the database maintained by the American Museum of Natural History. The listing confirms its taxonomic status and type locality.

Research Matters reported on September 5, 2026, that the discovery was made during field surveys in August 2025 and confirmed using DNA barcoding plus detailed physical inspection. Comparing the genetic code of the Buzawade specimens with other known species such as Gegeneophis mhadeiensis proved this was a unique lineage.

GKToday reported on September 7, 2026, that caecilians are limbless amphibians in the order Gymnophiona, adapted for burrowing, and that G. chandgadi is worm-like and flesh-coloured, with primary body rings along the full length and secondary rings on the posterior half. These ring-like folds, called annuli, are used in caecilian identification. The species is named after the local Chandgadi dialect of Marathi. A Zoological Survey of India press statement said the species was found residing in human-inhabited, residential, and agricultural landscapes, proving that critical subterranean biodiversity persists outside protected forest boundaries.

Analysis

What this really means is that the discovery is less about a single animal and more about what it says regarding how much of India's subterranean biodiversity remains undocumented. The fact that a new vertebrate species can be found in a village backyard, under wood piles and leaf litter, suggests that the boundaries of scientific exploration are not the same as the boundaries of protected areas. The Zoological Survey of India statement makes this point directly, noting that critical subterranean biodiversity persists outside protected forest boundaries.

The team's methods also highlight a shift in how such cryptic species are identified. Identification combined molecular data with detailed morphological and meristic analysis in a group often mistaken for earthworms or blind snakes. DNA barcoding was essential, because the animal's outward appearance overlaps with close relatives. Research Matters reported that comparing the genetic code of the Buzawade specimens with other known species such as Gegeneophis mhadeiensis proved this was a unique lineage.

The naming choice carries its own analytical weight. By calling the species Gegeneophis chandgadi after the Chandgadi dialect, the authors connect the scientific name to the linguistic heritage of the region. It also acknowledges local residents whose traditional ecological knowledge aided in locating the species. This is a small but meaningful shift in how taxonomic work credits the people who live alongside the biodiversity being described.

The bigger picture here is that India's caecilian checklist is still moving. India currently records 41 caecilian species among its 458 total amphibian species, and the Gegeneophis count now stands at 12, with 11 endemic strictly to the Western Ghats. A region that keeps yielding new species in backyards is a region whose natural history is far from completely documented.

Why It Matters

The discovery matters because caecilians are among the least studied amphibians in the world. They live underground, look like worms, and are often mistaken for earthworms or blind snakes. That combination makes them easy to miss and hard to count. When a new species is described from a residential and agricultural landscape, it changes the assumption that important biodiversity is confined to pristine forest.

The Western Ghats is a biodiversity hotspot and a major centre of amphibian diversity, spanning Maharashtra, Karnataka, Kerala, Tamil Nadu and Goa. Most Indian caecilians occur in the Western Ghats, where most species are endemic and inhabit tropical rainforests. Outside the Western Ghats, caecilians are also known from humid forests of northeastern India and a few humid regions of the Eastern Ghats. Each new species adds a data point to a region already recognised as globally important.

The team recommends listing the new species as Data Deficient until more surveys determine its population and range. That recommendation is a reminder that describing a species is only the first step. Conservation status depends on knowing where the animal lives, how many there are, and what threatens it. For now, G. chandgadi is known from a type locality in Buzawade village, Chandgad tehsil, Kolhapur district.

Next Up

Researchers noted that the northern Western Ghats is a hotspot for these animals, suggesting at least four other unknown lineages may still await a formal name. Future surveys will need to establish the population and range of G. chandgadi, and to test whether the other suspected lineages hold up under genetic scrutiny. The paper's DOI is 10.26515/rzsi/v126/i3/2026/173052.

For the scientists involved, the immediate task is to move the species from description to assessment. The International Union for Conservation of Nature status remains Data Deficient for now, and that will not change until the fieldwork catches up with the taxonomy.
