NAME: Otonycteris leucophaea (Severtzov, 1873) hemprichi
COMMON NAMES: Desert lpng-eared bat
DIMENSIONS: Body mass 17-30 g, head and body length 66-82 mm, tail
length is about 60 mm, forearm length 57-67 mm, wingspan 35-40 cm.

This bat was for decades treted as a synonim of O. hemprichi
Peters, 1859 (originally described from Egypt). However specific
distinctiveness of O. leucophaea was shown recently on the
basis of molecular and morphological data (Benda, Gvozdik, 2010).
DISTRIBUTION: From N. Iran, Tajikistan, Kyrgizstan, Turkmenistan,
Afghanistan, Pakistan and Kashmir. In mountain rich elevations up
to 2400 m ASL.
NATURAL HISTORY: Inhabits arid landscapes Use rock splits and human
buildings as day roosts. Foraging flight is low to the earth surface.
Feed on insects and small vertebrates; can hover over the prey and
take it from the substrate surface. Echolocation calls are low intensive,
sweep from ca. 40 to 18 kHz, with maximum energy at around 30-32
kHz. Natural history is poorly investigated. In summer females can
make nursing colonyes up to 60 individuals. Two newborns in litter,
reproduction is poorly known.
STATUS: Rare poorly investigated species. IUCN: "LR: lc".
