The recent discovery by researchers from the Taiwan Endemic Species Research Institute (TESRI) of the bat species Myotis adversus taiwanensis and Barbastella in the mountains of Nantou County has brought the number of known mammal species in Taiwan to 69.
直到最近「台灣省特有生物研究保育中心」在南投山區記錄到「高山鼠耳蝠」與「寬耳蝠」，如今台灣哺乳動物已多達六十九種。
