A new micro-snail species, Clostophis udayaditinus was recently officially described. The tiny specimen’s were identified in a karst – or limestone topographic formation – on Battambang’s Phnom Banan.

The species was named in honour of King Udayadityavarman II (1050-1066), the Angkor ruler who built Phnom Banan Temple, which later became the name of the hill.

The research was conducted in 2024 by Fauna & Flora Cambodia, in collaboration with the Ministry of Environment and specialists from Chulalongkorn University, Mahidol University and KhonKaen University. The expedition received funding support from the EU, through the ‘”Bcoming project”.

Prior to the study, 13 species from five genera of terrestrial snails had been recorded in Cambodian karsts, but no species from the genus Clostophis had ever been documented.

“This discovery marks the first record of the microsnail genus Clostophis (usually less than 2mm) in Cambodia and describes Clostophis udayaditinus as a new species to science — making it the 20th Clostophis species recorded globally,” said a joint statement from Fauna & Flora and the ministry.

Due to their isolated nature, karsts in Cambodia are rich in endemic species. This discovery is significant as it marks the first record of the genus Clostophis in Cambodia, highlighting the uniqueness of these habitats and the importance of their conservation.

Khvay Atitya, environment ministry spokesperson, explained that the discovery is extremely valuable in terms of scientific research into Cambodia’s natural resources and biodiversity.

“The growing number of newly recorded species demonstrates the harmonious relationship between humans and nature. It also reflects our success in preserving natural resources and the environment, allowing continuous biodiversity discoveries,” he claimed.

He added that the ministry will continue its research and encouraged further scientific studies in protected natural areas to identify and document even more biodiversity.
