Taxonomy and etymology
It was described as a new species in 2005. The holotype was collected in 2003 just outside the Tsingy de Bemaraha Strict Nature Reserve in Madagascar. Its species name "tandrefana" is Malagasy for "from the west".

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.
