On 28 January, Dr. Wiyawat Jaitrong, a senior specialist researcher at the National Science Museum, stated that Thai researchers have discovered a new ant species in a rubber plantation near Khao Ting Cave, Lallipang Subdistrict, Palian District, Trang Province. It is scientifically named Tetraponera sirindhornae Yodprasit, Tasen & Jaitrong, 2025, in honor of Her Royal Highness Princess Maha Chakri Sirindhorn, who plays a vital role in promoting science, natural resource conservation, and biodiversity in the country. Tetraponera sirindhornae is medium-sized with a smooth, shiny body and distinctive morphological traits. It is the first species in the Tetraponera genus to have two worker sizes, whereas others have only one. A key identifying feature is a clear gap between the mandible teeth when closed, a characteristic never before seen in this genus.
Associate Professor Dr. Nopparat Phutthakan from the Biology Department, Faculty of Science and Technology, Rajamangala University of Technology Thanyaburi, who participated in the research, explained that the ants build nests in dry rubber tree branches still attached to the tree, with only one nest found. The habitat faces risks as the rubber plantation area near Khao Ting Cave—a significant tourist site—is being transformed into shops and facilities. Since the initial discovery, researchers have not found the ants again. This finding underscores the need for land development and tourism management that balances biodiversity conservation alongside land use, to prevent the extinction of rare or newly recognized species.
