Rare Narrow-Banded Rain Snake Found In Mizoram Highlights India's Hidden Biodiversity
In a significant boost to India's wildlife conservation and biodiversity research, scientists have discovered a new species of non-venomous snake in the forests of Mizoram. Named the narrow-banded rain snake (Smithophis leptofasciatus), the species belongs to the Smithophis genus and was previously misidentified as Smithophis bicolor. The discovery was made by researchers from Mizoram University in collaboration with conservation group Help Earth. DNA analysis and physical traits confirmed it to be a genetically distinct species. The name leptofasciatus from Greek and Latin roots refers to the snake's slim cream-yellow bands over a glossy black body. Locally, it's known as "Ruahrul". The snake was found in the cool, rainy hill forests of eastern Mizoram, near slow-moving mountain streams at elevations of 900–1,200 meters. The species is nocturnal and prefers monsoon conditions, making it elusive and difficult to study. During their research, scientists observed a gravid female in captivity laying six eggs, providing rare insight into the reproductive cycle of the species. Despite its appearance, the snake is completely harmless to humans. This marks the third known species of Smithophis discovered in Mizoram, following Smithophis atemporalis and Smithophis mizoramensis. The finding reinforces the state's reputation as a biodiversity hotspot, especially for under-documented species like snakes. Researchers warn that while the discovery is exciting, the fragile forest ecosystems where the snake was found are under constant threat from deforestation and development. They urge the government and public to take conservation efforts more seriously.

Mizoram University researchers discover new snake species
Agency: PTI Last Updated: Aizawl, Aug 7 (PTI) Researchers from the Zoology Department of Mizoram University have discovered a new species of snake — 'Smithophis laptofasciatus'. The new species was discovered after studying its scales, morphological features and DNA during herpetological expeditions, Professor H T Lalremsanga, who heads the Zoology Department, said. The findings of the new research were published in the international scientific journal, 'Taprobanica' (The Journal of Asian Biodiversity) on August 5, he said. According to Lalremsanga, five Smithophis snake species have been discovered so far worldwide. They are mainly found in India's Northeast and neighbouring regions, he said. Of the five species, two species — Smithophis atemporalis and Smithophis mizoramensis — were discovered in Mizoram, he said. Although the new finding was described as Smithophis bicolour, which was discovered in Meghalaya in 1855, a thorough study revealed that Smithophis laptofasciatus differs from the latter in its DNA and morphological features by 11.5 per cent, which confirmed it to be a new species, he said. Smithophis laptofasciatus is non-venomous and mainly feeds on worms, he said, adding it lives in dense forests.

Rare narrow-banded rain snake found in Mizoram highlights India's hidden biodiversity
Source: TAPROBANICA A rare species of rain snake has been discovered in the montane forests of Mizoram, offering new insight into India's rich but often overlooked biodiversity. Named Smithophis leptofasciatus, or the narrow-banded rain snake, this striking reptile features glossy black scales and incomplete yellow bands. Its discovery reinforces Mizoram's status as a biodiversity hotspot and underscores the urgent need for conservation in the region's fragile forest ecosystems. As habitat loss continues to threaten lesser-known species, this finding serves as both a scientific breakthrough and a call to action for preserving Northeast India's unique ecological heritage. New snake species found in Mizoram: Meet the rare rain snake Smithophis leptofasciatus Smithophis leptofasciatus is visually distinct, featuring a glossy black body with narrow, incomplete cream or lime-yellow bands. These striking patterns, along with its genetic distinctiveness, set it apart from other species in the Smithophis genus. The species was described based on live sightings and two collected specimens. The scientific name "leptofasciatus" combines Greek and Latin roots meaning 'narrow-banded,' reflecting the snake's appearance. The researchers also proposed a local name, 'Ruahrul' in the Mizo language, linking the find to the region's cultural identity. Habitat and behaviour of the rare rain snake Smithophis leptofasciatus This new species thrives in cool, shaded montane forests close to freshwater streams, typically at elevations between 900 and 1,200 metres above sea level. It is a nocturnal and semi-aquatic species, most commonly spotted during the monsoon season. Some notable behavioural traits include Preference for moist, forested stream zones Nocturnal activity pattern Semi-aquatic movement Sightings near flowing water and leaf litter Researchers also had the rare opportunity to observe its reproductive behaviour. A gravid female, kept briefly in captivity for study, laid six eggs—offering valuable insight into the breeding habits of this elusive snake. Mizoram: A growing hotspot for reptile diversity With the addition of S. leptofasciatus, Mizoram now hosts three known Smithophis species, including S. atemporalis and S. mizoramensis. This underscores the rich ecological tapestry of the region and the importance of further scientific exploration. The state's mix of dense rainforests, mountainous terrain, and freshwater ecosystems creates a unique environment that supports a wide variety of life forms, many still awaiting discovery. Why this discovery matters for biodiversity and conservation The discovery serves as a strong reminder of the hidden biodiversity in India's Northeastern states. However, researchers have expressed concern about the narrow habitat preference of the species, which could make it vulnerable to environmental threats such as: Deforestation for development or agriculture Pollution of forest streams Habitat fragmentation due to infrastructure projects Such changes could severely affect the survival of this and other species that rely on undisturbed montane ecosystems. Urgent conservation measures needed to protect Mizoram's rare rain snake and forest biodiversity The study's findings underscore the urgent need for enhanced conservation measures in Mizoram's montane forests. Targeted ecological surveys are essential to identify other potentially undiscovered species that may be hiding in this rich biodiversity hotspot. Protecting forest habitats, especially around freshwater stream zones where the newly discovered rain snake thrives, must be a priority. Sustainable land-use practices should be implemented in these ecologically sensitive areas to minimise environmental degradation. Equally important is raising community awareness and involving local populations in conservation efforts. Safeguarding Mizoram's montane forests is not just crucial for the survival of Smithophis leptofasciatus but also vital for preserving the region's broader ecological integrity. Smithophis leptofasciatus is more than just a new name in science; it represents the fragile richness of our ecosystems and the need to act before it's too late. With every new discovery, the importance of balancing development with environmental responsibility becomes clearer. This find should inspire more research, conservation funding, and environmental education efforts, not just among scientists but also among students, local communities, and young nature enthusiasts across the country.

Creature found as roadkill identified as footlong new species in India. See it
From sharp-toothed sharks to spiders a bit too large for comfort, some animals have earned a scary and intimidating reputation. Snakes are a central part of this group of animal villains, but while boa constrictors or venomous rattlesnakes have earned it, not all snakes warrant a fight-or-flight response. In the lush forests of Mizoram, India, a newly discovered species was described as 'timid' and 'gentle,' and even chose to keep its mouth shut when being handled, researchers said, in a study published Aug. 5 in the peer-reviewed journal Taprobanica. Smithophis leptofasciatus, or the narrow-banded rain snake, was discovered in and around small streams as well as under the leaf litter, rocks and decaying logs on the forest floor, according to the study. While two of the snakes were found living, a third was found as roadkill in the area, and five others were spotted but not collected for the study, researchers said. The narrow-banded rain snake is considered 'small' for its group, though it can measure more than 16 inches long, according to the study. Its coloration is described as a 'shiny dark or a black background intermixed with distinct, narrow and creamish-white or yellowish-lime transverse bands' that are narrow and encircle the body in incomplete bands, researchers said. The snake's head is 'elongated' and 'moderately large' in proportion to its body, with a large and broad snout, according to the study. The eyes are also considered 'moderately large.' The species name, leptofasciatus, is derived from the Greek word 'leptos' and Latin word 'fasciatus' and means 'narrow banded,' referring to the snake's pattern, researchers said. Researchers found the snakes both near and in the water of the streams, suggesting they are at least semiaquatic. The new species is also nocturnal, according to the study. 'All handled specimens were very timid, gentle, showing no inclination to bite when handled,' researchers said. 'In captivity individuals voraciously fed on earthworms.' Researchers also found the brood of a female and noted white, oval and 'leathery' eggs, according to the study. The new species was previously considered part of another known species, Smithophis bicolor, which is found in the Meghalaya region of India. However, recent studies have shown genetic differences between the snakes found there and the ones identified in Mizoram, meaning geographical separation has led to distinct lineages, according to the study. Mizoram is in northeastern India, west of the border with Myanmar. The research team includes Lal Muansanga, Jayaditya Purkayastha, Vanlal Hruaia, Mathipi Vabeiryureilai, Lal Biakzuala, Ht Decemson, Hmar T. Lalremsanga and Sanath C. Bohra.

New species of rain snake recorded in Mizoram
GUWAHATI A team of researchers from Mizoram University and Guwahati-based biodiversity conservation group Help Earth have recorded a new species of rain snake from an elevated tropical forest in Mizoram. The narrow-banded rain snake (Smithophis leptofasciatus) has been described in the latest issue of Taprobanica: The Journal of Asian Biodiversity. The authors of the study — Lal Muansanga, Jayaditya Purkayastha, Vanlal Hruaia, Mathipi Vabeiryureilai, Lal Biakzuala, Ht Decemson, Hmar T. Lalremsanga, and Sanath C. Bohra — proposed 'Ruahrul' as the new-to-science snake's Mizo name. Rain snakes are so named because they become more active and visible during the rainy season. The authors said the description was based on detailed morphological and molecular analyses of two collected specimens, along with observations of several live individuals. The new species is distinguished by its narrow, incomplete creamish-white or yellowish-lime transverse bands on a shiny black body — features that set it apart from its close relatives. 'Our study confirmed that this snake, previously identified as Smithophis bicolor, is a genetically and morphologically distinct species. It not only adds to the growing diversity within the genus Smithophis, but also redefines the distribution of previously known species,' Dr. Purkayastha, one of the corresponding authors, said. The species name leptofasciatus is a Greek and Latin hybrid, meaning 'narrow-banded', referencing the snake's distinctive dorsal markings. The narrow-banded rain snake was found inhabiting humid, shaded microhabitats near small streams in forests between 900 and 1,200 meters above sea level. Its semi-aquatic, nocturnal lifestyle was revealed through field observations during the monsoon. A gravid female observed in captivity laid six eggs, providing rare reproductive data for this elusive group. This is the third Smithophis species to be described from Mizoram after the Smithophis atemporalis and the Smithophis mizoramensis. 'The new species reinforces Mizoram's importance as a biodiversity hotspot. The State plays a central role in the evolution and diversification of this genus,' said Dr. Lalremsanga, the co-author and head of the Developmental Biology and Herpetology Lab at Mizoram University. The study recommended additional surveys and habitat assessments, as the narrow range and forest dependency of the narrow-banded rain snake suggest it may be vulnerable to habitat degradation.
