The colour of their fur varies with latitude, from pale ochraceous in the north to coffee-brown in the south.
...
Because of their small size and low metabolic rate, the bats often enter a daily period of torpor during which their body temperature falls to just 0.5 °C above ambient.
With no references or previous knowledge of this species or specialist knowledge of bats, I would nevertheless bet that variation is to improve their absorption of heat from sunlight, which is more vital the further you get from the equator. Although, hmm, that's kind of hard to associate with this:
They emerge at dusk, and feed for about three hours before returning home to roost; unlike most other bats they do not feed again later in the night.
