The Vietnamese brown horseshoe bat is medium-sized for a horseshoe bat, with a forearm of 43.8–47.2mm and a weight of 9–9.5g. The dorsal fur is bicoloured, yellowish-brown at the base and cinnamon-brown at the tips, the underside is paler, and the flight membranes are uniformly dark brown (Wikipedia, general species account).
The general species account places it in Cambodia, Laos, Myanmar, Thailand and Vietnam; the Mammal Diversity Database also lists China, so its occurrence there is unconfirmed here.
