Triaenops menamena is a bat found in the drier regions of Madagascar. Because of its wide range, common occurrence, and tolerance of habitat degradation, it is not considered to be threatened. It often roosts in large colonies and eats insects such as butterflies and moths.
About Triaenops menamena in brief
Triaenops menamena is a bat found in the drier regions of Madagascar. It was known as Triaenop rufus until 2009, when it was discovered that that name had been incorrectly applied to the species. Because of its wide range, common occurrence, and tolerance of habitat degradation, it is not considered to be threatened. It often roosts in large colonies and eats insects such as butterflies and moths. The maximum frequency of the echolocation call averages 94. 2 kHz. Its fur color is variable, ranging from reddish brown to gray, but it is generally darker than the species in the closely related genus Paratariaenops. It is currently one of four living species of the genus Triaanops. An extinct species, Triaonops goodmani, is known from northwestern Madagascar. The specific name is Malagasy for’reddish’, referring to the animal’s coloration.
It has a forearm length of 50 to 56 mm in males and 46 to 53 mm in females, this is a medium-sized bat. In 1881, Alphonse Milne-Edwards described two new species of bat in the genus. They were the reddish Triainop rfus and the larger, gray T. humbloti. A 2009 revision by Petr Benda and Peter Vallo split off the African T. afer and the Yemeni T parvus from T. persicus and removed three other species, including two from Madagascar, to the separate genus Par atriaenips. They found that T menamena was closest to the African species of Paratiaenops from mainland Africa; the species of T men amena and Paratraenops independently reached Madagascar by colonization of the island about 660,000 years ago.
