It was also compared with M bocagii (which is sympatric and similar in size), M daubentonii from Europe (which several authors reported as being very similar), and M scotti (another sub-Saharan African species of similar size). Based on cranial and external morphology and morphometric data, Adam's specimen was found to be a new species. It differs in having the combination of a very weakly concave forehead region of the skull, relatively long feet, wing membranes attached to the bases, of the tibiae, and no backwardly-curved hairs on the margin of the interfemoral membrane. It was collected in a limestone cave at Loudima in the Republic of Congo, in degraded rainforest near a river.Keywords: bat; new species; nomenclature; taxonomy; Africa; Central Africa; Congo; Eastern Hemisphere; Sub-Saharan Africa; World; Chiroptera; Megalopus; Myotis; Myotis longipes; Vespertilionidae Central Africa; Description; Myotis megalopus; Myotis sp. nov.20052015-12-11
