Abstract

Wrinkle-lipped Bat (Mops plicatus) is a widespread species but still poorly studied in Vietnam. Prior to the present study, it was recorded from the following provincial localities of Vietnam: Lang Son, Dong Nai, Hanoi, Phu Tho, and Bac Kan. Of which, its distributional record in Hanoi has been purely based on a single specimen collected in 1974. On the other hand, one specimen was collected in 1960 from the “Gulf of Tonkin” of Vietnam without specific information about the locality. Between 2020 and 2021, we conducted a series of bat surveys in northern Vietnam. Results from the surveys included records of a lactating female and its echolocation calls in Ha Long Bay and an adult female in Hanoi. Remarkably, the echolocation parameters of the individual in Ha Long Bay are different from those in published descriptions. This paper provides new data in echolocation and distribution of Mops plicatus in Vietnam.
