Ears are relatively long and narrow, with small but distinct notch; tragus is narrow, straight, slightly bend forward near pointed tip, and about one-third the ear length. Wings attach at base of outer toe, and feet are ¢.50% oftibia length. Frontal region of skull rises gently, nearly flat at tip; lambdoidal and sagittal crests are absent; rostrum is narrow in front; canines are relatively small and only slightly higher than their respective posterior premolars; all premolars are within their tooth rows, although P* and P, are much smaller than the others; and lower molars are myotodont.

Habitat. Lowland and montane forest habitats at known elevations of 40-2600 m.

Food and Feeding. The Long-toed Myotis eats small insects captured in air.

Breeding. Births of Long-toed Myotis probably occur in May-June, depending on elevation, because lactating females have been reported during this time. Males with enlarged testes were reported in August-March.

Activity patterns. Long-toed Myotis roost in artificial subterranean roosts (e.g. tunnels) and caves where breeding females have been reported roosting in small holes or crevices. They probably use tree hollows.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Least Concern on The IUCN Red List. The Longtoed Myotis appears to be widespread and relatively common in Taiwan. It does not face any known major threats, but roost disturbance might be a local threat.
