Geographic range

Native: mainland China (Yunnan), India (north), Malaysia (Peninsular), Nepal, Singapore, Thailand, Vietnam.

Introduced: mainland China (Hainan, Hong Kong, Macau), Mascarene Islands, India (Kerala).

New record for Hainan.

Ecology

Collected in rubber plantations and urban parks in Hainan, and rubber plantations, secondary forest and mature forest for Thailand and Vietnam. Elevation from 140 to 902 m.

Comments

The tramp status of the species was suggested in Tang et al. (2019) given its association with relatively disturbed habitats in Hong Kong and a recent record from Mauritius. New records from Hainan Province also originated only from habitats such as rubber plantations and urban parks. Its presence in Guangdong and Guangxi provinces (possibly as a tramp species), as well as in Myanmar, Laos and Cambodia (as a native species) is also likely. We thus recommend further sampling, in particular within anthropogenic habitats (e.g., urban parks) to detect the potential presence of this species within China and nearby countries.
