It is a small bat, weighing only 3.5–4 g (0.12–0.14 oz).
Its forearms are 28–30.4 mm (1.10–1.20 in) long.
Its ears are rounded with smooth margins, measuring 12.3–12.8 mm (0.48–0.50 in) long.
The ears are brown in color, with the base of the ear a lighter brown.
The tragus is white and short, at 7.4–7.6 mm (0.29–0.30 in) long.
Their dorsal fur is ashy-gray, with some hairs tipped in a reddish-orange tint of brown.
Other dorsal hairs are tipped in a charcoal black color.
Their heads, backs, uropatagia, and feet have silver-gold guard hairs.
On their ventral side, their hairs are dark gray at the base, but whitish gray at the tips.
Their thumbs are relatively long, at 8.2–8.8 mm (0.32–0.35 in) long.
The calcar is well-developed, but lacks a keel.[2]
Biology
It eats insects, foraging for them only 2–3 m (6.6–9.8 ft) above the forest floor.
It likely roosts in leaves or hollow trees.[1]
Range and habitat
It occurs in moist, evergreen lowland rainforests in the Narathiwat Province of southern Thailand.
It has only been encountered in the Bala Forest of Hala-Bala Wildlife Sanctuary.[1]
Conservation
It is currently evaluated as critically endangered by the IUCN.
It meets the criteria for this evaluation because its area of occupancy and extent of occurrence are both very small, at less than 4 km2 (1.5 sq mi).
Also, there is a projected decline in the quality and extent of their habitat.
It is threatened by habitat loss due to deforestation and the expansion of agriculture.[1]
