The little long-fingered bat is small and has seasonal variation in coat color. It hunts insects at night and roosts in groups in caves and other sheltered places.
Its coat ranges seasonally from gray-black to pale fawn, and it is smaller than a close relative described in the account.
The Little Long-fingered Bat (Miniopterus australis) was captured at 2,117 metres above sea level on Mount Wilhelm, Papua New Guinea. Nets along the elevation transect caught two bats; the other was at 1,718 metres. The paper compared these with a previous highest record of 1,500 metres: the two sites are 617 and 218 metres above it, respectively.
At 2,117 metres, the net stood beside a human-made track in closed-canopy primary forest. This point lay on the north-facing Mount Wilhelm transect, which covered elevations from 200 to 3,700 metres. Table 1 lists the two captured bats as one female and one male.
