|Western yellow bat|
Goodman, Jenkins & Ratrimomanarivo, 2005
It was described as a new species in 2005. The holotype had been collected in 2003 just outside the Tsingy de Bemaraha Strict Nature Reserve in Madagascar. Its species name "tandrefana" is Malagasy for "from the west".
It has a forearm length of approximately 47 mm (1.9 in), a tail length of 46 mm (1.8 in), and an ear length of 13 mm (0.51 in). The holotype weighed 14.2 g (0.50 oz). The fur of its back is dark brown, while its belly fur is a medium shade of brown. It uses echolocation to navigate and find prey: it utilizes steep frequency-modulated echolocation (FM) as well as that of a quasi-constant frequency (QCF). Its echolocation reaches maximum energy around 48.2 kHz. Minimum frequency is 42.2 kHz, while maximum frequency is 91.2 kHz.
As of 2008, it is listed as a data deficient species by the IUCN. It meets the criteria for this classification because only a few individuals have ever been documented and no data is available regarding its population size or the threats the species faces.
As of March 2015, the IUCN Red List of Threatened Species identified 6087 data deficient species in the Chordata phylum (Animalia kingdom).List of bats described in the 2000s

Bats are one of the major components of the indigenous mammalian fauna of Madagascar, in addition to tenrecs, lemurs, euplerid carnivores, and nesomyine rodents. Forty-six bat species have so far been recorded on Madagascar, of which thirty-six occur only on the island. However, new species continue to be discovered, causing the number of species to rise rapidly; for example, Nick Garbutt's Mammals of Madagascar (2007) listed only 36 species. Most Malagasy bats have their origins in nearby mainland Africa, but on at least three occasions—Pipistrellus raceyi, Pteropus rufus, and the species pair Emballonura atrata–E. tiavato—bats have colonized Madagascar from Asia.List of data deficient mammals
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 783 data deficient mammalian species. 14% of all evaluated mammalian species are listed as data deficient.
The IUCN also lists 30 mammalian subspecies as data deficient.
Of the subpopulations of mammals evaluated by the IUCN, four species subpopulations have been assessed as data deficient.
This is a complete list of data deficient mammalian species and subspecies evaluated by the IUCN. Species and subspecies which have data deficient subpopulations (or stocks) are indicated. Where possible common names for taxa are given while links point to the scientific name used by the IUCN.Scotophilus
Scotophilus is a genus of vespertilionid bats commonly called yellow bats. They are found in southern Asia and Africa.Vespertilioninae
