Geographic range

Mainland China (Hainan, Hong Kong, Macau), Japan (Ryukyu Islands), Taiwan.

New record for Hainan.

Ecology

Collected in primary forest, secondary forest, rubber and agro-rubber plantations.

Comments

This species has previously only been recorded from the Ryukyu Islands, Taiwan, Hong Kong and more recently in Macau ( Brassard et al. 2020). This disjunct geographical range was proposed as an indication of its presence in other parts of southeast China, including Hainan ( Tang et al. 2019). Hence, with more sampling efforts, it should be recorded in surrounding provinces such as Fujian and Guangdong.
