( J. Fischer , 1829)

The spur sheath tail ( Centronycteris maximiliani ) is a tropical bat species from the family of the smooth-nosed cantilever tails (Emballonuridae). Because of her shaggy hair, she is known as the Shaggy Bat in English . Together with the Thomas spur sheath tail ( Centronycteris centralis ), which was considered a subspecies of the spur sheath tail until 1998, it forms the genus Centronycteris . The art epithet honors Maximilian zu Wied-Neuwied .

features

The spur sheath tail resembles a ball of fluff. The head-torso length is 41 to 57 mm, the tail length 20 to 32 mm, the hind foot length 7 to 9 mm, the forearm length 41.5 to 49.0 mm, the ear length 17 to 19 mm and the weight 4.5 to 6.0 grams. The top is smoke brown with a yellowish-orange tint. The fur hair is very long and woolly. The head, including the nose and chin, is woolly hairy. The ears have protruding parallel ridges on the inner edge. The long tail protrudes to the middle of the tail membrane. The outstretched tail membrane is longer than the legs. It is heavily marked with parallel rows of spots that are crossed by protruding branched veins. The reddish body hair extends to the base of the tail membrane. The underside is a little more yellowish than black. In contrast to most of the other representatives of the Diclidurini tribe , there are no sack-shaped glands on the wings.

distribution and habitat

Distribution map of the spur sheath tail

The spur sheath tail inhabits primary and secondary rainforests. The distribution area extends from northeastern Peru over Brazil , Colombia , French Guiana , Guiana and Suriname to southern Venezuela .

Way of life

The spur sheath tail feeds on insects that are preyed on in flight. When foraging for food, which was observed in the late afternoon, it makes slow, flapping wings. His sleeping places are in tree hollows.

status

The IUCN lists the spur sheath tail in the category “not endangered” ( least concern ). However, deforestation poses a potential threat.
