Identification:
These bats are small in size. The body length is 40-50 mm, the tail is approximately 18-25 mm long, the forearm length is < 43 mm, the ear length is 16-19 mm, the foot length is 9-10 mm, the skull length is 18.3 mm, the jaw length is 6.7 mm, and the zygomatic arch width is approximately 8.7 mm. The posterior noseleaf is narrow, with an elongated apex. The mid and posterior nasal regions are raised. The supraorbital region is depressed, not extending the entire length from front to back. The mid and anterior regions are convex but are restricted by the anterior region where the apex meets the supraorbital region. In lateral view, the mid and anterior regions are slightly convex, and the posterior region is depressed.
Biology and Ecology:
This species typically inhabits caves and tunnels, often living in colonies of up to several hundred individuals. They usually leave their roosts to forage at dusk. They fly quickly and at high speeds to capture insects (beetles, dipterans) during the rainy season.
Distribution:
These species are found throughout Southeast Asia, including Thailand, Laos, Vietnam, Malaysia, the Philippines, and Borneo. In Vietnam, this species has been found in Lai Chau (Muong Muon).
Value:
This is a rare species, with scientific research value and the ecological benefit of controlling harmful insects in nature.
