Endangered Bat Species Discovered in Corsica

December 20, 2023

Researchers have identified a new and highly rare species of bat on the French island of Corsica, located in the Mediterranean. The discovery, published in the journal Revue suisse de Zoologie in October, highlights the uniqueness and vulnerability of this newfound creature.

Previously Unknown Species

After conducting DNA analysis on tissue samples, scientists determined that the bat discovered in Corsica belongs to a previously unknown species within the genus Myptis, which boasts more than 120 species across six continents. The newfound species has been named ‘nustrale’ in the Corsican dialect, meaning “ours.” The researchers noted that this bat may have been genetically isolated for a significant period.

Characteristics

Described as medium-sized, measuring approximately an inch and a half in length, the ‘nustrale’ bat is characterized by its grey color, long ears, and a hairy face. Notably, it features a distinctive dark spot on its lower lip, setting it apart from other members of the Myptis genus.

Habitat and Behavior

These bats are found in Corsica’s mountainous terrain, hunting in dense evergreen forests and roosting in cliffs and rocky outcroppings. Researchers also discovered a colony of around 60 individuals in an artificial tunnel. The species appears to be localized to mountain forests, making it unique to Corsica.

Vulnerability

Given its limited distribution, small population size, and restricted connectivity, the ‘nustrale’ bat is deemed highly vulnerable to climate change. The researchers emphasize that the species should be classified as endangered due to these factors. The findings underscore the importance of conservation efforts to protect this newly identified and vulnerable species in Corsica.
