The western small-footed bat (''Myotis ciliolabrum''), also known as the western small-footed myotis, is a species of vesper bat native to North America. ==Description== Western small-footed bats are relatively small bats, having a total length of , and a wingspan of about . They weigh just , with females being larger than males. Their fur is yellowish-brown in color, with paler, sometimes white, underparts. The muzzle and chin are black, as are the long ears. The tail is in length, but is almost entirely enclosed within the uropatagium, with only the tip extending beyond it. As the common name indicates, the feet are unusually small, being about half the length of the tibia. The bats have a wing aspect ratio of 6.1 and a wing loading of 6.7 N/m2, which are both relatively low values for bats. They are very similar in appearance to the closely related California myotis, with which they share some of their range; the two species can be distinguished in that the latter does not have the black "face mask" of the small-footed species.〔
