The genus Myotis Kaup, 1829 is unique among mammals in
its high diversity and near-global distribution. The genus
includes over 100 species (Simmons 2005), with representa-
tives in nearly all biogeographical regions. The biogeographic
reconstruction by Ruedi et al. (2013) retrieved East Asia as the
place of origin of the genus, with the divergence between New
and Old World lineages dating from the mid- to late Miocene.
Ruedi et al. (2013) suggested the Bering Strait as the gateway
for New World colonization, with an ancestral form reaching
the Neotropics by the Late Miocene. Early New World Myotis
