[2] It is endemic to Taiwan[2][3][4] and widely distributed at elevations up to 3,000 m (9,800 ft) above sea level.

Skin is rough and covered with pointed tubercles of various size.

[3] B. bankorensis are found in a range of habitats at elevations up to 3,000 m (9,800 ft):[3][4] broadleaf forests, cultivated fields, mixed forests, and orchards.

[1][3][4] One study found that a temperate population could breed throughout the year, while a subtropical population only bred during the cooler part of year, from September to March.

[5] While B. bankorensis is a common species, habitat loss remains a threat to it.
