Triaenops menamena is a bat in the genus
Triaenops found on
Madagascar, mainly in the drier regions. It was known as
Triaenops rufus until 2009, when it was discovered that that name had been incorrectly applied to the species.
Triaenops rufus is a
synonym of
Triaenops persicus, a closely related Middle Eastern species.
Triaenops menamena is mostly found in forests, but also occurs in other habitats. It often roosts in large colonies and eats insects such as
butterflies and moths. Because of its wide range, common occurrence, and tolerance of
habitat degradation, it is not considered to be threatened. With a forearm length of 50 to 56 mm (2.0 to 2.2 in) in males and 46 to 53 mm (1.8 to 2.1 in) in females, this is a medium-sized bat. Its fur color is variable, ranging from reddish-brown to gray, but it is generally darker than the species in the closely related genus
Paratriaenops which also occur on Madagascar. The skull contains a pronounced swelling around the nose and the second upper
premolar is displaced outside the toothrow. The maximum frequency of the
echolocation call averages 94.2 k
Hz and the species can easily be recognized on the basis of its call. (
