New trapdoor spider species discovered in Kolhapur grasslands

Kolhapur: A new species of trapdoor spider has been discovered in the grasslands of Kolhapur district by a joint team of researchers from the Thackeray Wildlife Foundation and Shivaji University, Kolhapur (SUK). The findings were published on Feb 4 in the Journal of Natural History, a prestigious international research publication based in the UK. Named Titanidiops kolhapurensis after its place of discovery, the species is already facing a grim future. Researchers warned that the spider is on the verge of local extinction due to rapid habitat degradation. The discovery is a centerpiece of Satpal Gangalmale's ongoing doctoral research at Shivaji University's department of zoology, conducted under the guidance of entomologist Sunil Gaikwad. The team also included renowned researchers Tejas Thackeray and Akshay Khandekar from the Thackeray Wildlife Foundation. Explaining the naming and characteristics, Satpal Gangalmale said, "These spiders are popularly known as ‘trapdoor spiders'. In Marathi, they are nicknamed ‘darkari koli' because of their unique ability to craft hinged doors for their burrows. Based on their specific tooth structure and the arrangement of their eight eyes, they were classified under the Titanidiops genus." The "dark spider of Kolhapur" has been recorded in specific pockets, including the Shivaji University campus, Shenda Park, the Kolhapur Chitranagari area, and Puikhadi hill. A significant finding of the study was the spider's habitat preference. While researchers found a healthy presence of the species in natural forests and native grasslands, they were notably absent in areas overtaken by exotic tree plantations, such as Gliricidia sepium (commonly known as Undirmari). S.M. Gaikwad emphasised the precarious state of the species' environment. "This spider builds vertical or slanted burrows in flat or sloping grassy meadows. These entrances are masterfully camouflaged to blend with the soil, making them nearly invisible to the naked eye," he said. Gaikwad warned that the spider's survival is tied to the preservation of these specific landscapes. "The habitat near the city is being rapidly transformed by construction, intensive agriculture, and the planting of non-native trees. If these human-induced changes are not checked, this newly discovered species faces a serious risk of vanishing from the region entirely."
