Percival's small-eared trident- leaf -nose ( Cloeotis percivali ) is a small bat species that occurs in a disjointed range in southern and southeastern Africa. The species was named after the British gamekeeper Arthur Blayney Percival , who worked in East Africa.
features
Percival's small-eared trident leaf noses reach a head-trunk length of 2.4 to 3.6 cm and a wingspan of 20 to 23 cm and are thus the smallest African round-leaf noses . The fur is soft, dense and silky. In the middle of the back, the hair is 7 to 8 mm long. The fur on the back is light gray-brown, slate gray or light brownish-orange. The face is light, yellowish or almost white and brown or gray around the eyes, the nasal sheet and the mouth. The wings are gray to gray-brown. Both sexes are colored the same. The nasal blade is small, almost round and has three jagged protrusions in the rear area. The muzzle is short, wide and flat. The ears are gray-brown, round, clearly separated from each other and partially covered by fur. The calcar is weak and poorly developed. The tail only protrudes over the tail membrane with a vortex. In the upper jaw, the incisors have a second point.

Habitat and way of life
Percival's small-eared trident-leaf nose is found in Swaziland and neighboring areas of South Africa, a large part of Zimbabwe , some areas of Zambia, southern Katanga and two small areas in southeastern Kenya and on the coast of Tanzania. The distribution area is of different forest types, such as dry and wet miombo , mopane passed and various mixed forest types. During the day, Percival's small-eared trident-leaf nose rests in loose groups (ie without physical contact) of a dozen to several hundred specimens. Percival's small-eared trident-leaf nose feeds almost exclusively on moths. The shape of the wings suggests that they are hunted in dense vegetation. The locating calls of the animals have a frequency of 208 to 212 kHz. This prevents the moths, which can best hear frequencies of 20 to 50 kHz and are deaf in the frequency range of the calls of Percival's small-eared trident-leaf nose, from being able to avoid the approaching bats. Percival's small-eared trident-leaf noses get a single cub. More details about reproduction are not yet known.
