“…A lowland and mountain form of M. formosus were also distinguished and referred to M. flavus and M. watasei, respectively (Lin et al 2004;Jiang et al 2010), suggesting that the current taxonomy and species assignments in Taiwanese Myotis do not reflect the real diversity. Molecular studies further challenged the classical taxonomy by showing that taiwanensis was inadequately assigned to M. adversus and should rather be considered as a species on its own (Han et al 2010), and that latirostris was not related to M. muricola, not even to any other species of Myotis (Stadelmann et al 2007;Lack et al 2010;Ruedi et al 2013). However, none of these molecular surveys referred the analyzed specimens directly to available type material for a proper systematic arrangement, implying that their taxonomic recommendation could be questionable, as demonstrated in a recent review of species in the Chrysopteron subgenus (Csorba et al 2014;Kuo et al 2014).…”

In taxonomic accounts, three species of Myotis have been traditionally reported to occur on the island of Taiwan: Watase's bat (M. formosus watasei Kishida), the Formosan broad-muzzled bat (M. muricola latirostris Kishida) and the Formosan mouse-eared bat (M. adversus taiwanensis Linde). The discovery in 1997 of an unknown taxon not fitting to the description of any of these species encouraged us to re-examine more thoroughly the systematics and phylogeny of Myotis bats inhabiting Taiwan. We used a combination of morphologic and molecular methods to aid the identification of the different taxa from this island and reconstruct their phylogenetic relationships. Multivariate analyses based on 17 craniodental characters of 105 specimens caught across Taiwan and further external characters allowed us to discriminate eight taxa of Myotinae co-occurring on this island. A subset of 80 specimens were further sequenced for the cytochrome b gene (1140 bp) and subjected to phylogenetic reconstructions including representative species from adjacent China and from all main lineages of the worldwide Myotis radiation. These molecular reconstructions showed that the Myotinae from Taiwan are phylogenetically diverse and are issued from several independent clades. The genetic results were completely congruent with the phenetic groupings based on craniodental and external morphology, as each of the eight Taiwanese taxa proved to be reciprocally monophyletic. Two unnamed taxa that did not fit into any of the known species were described as species new to science. Furthermore the taxon latirostris usually associated to the Asian M. muricola, was phylogenetically and morphologically distant from any other known Myotis and was assigned here to the fossil (Miocene) genus Submyotodon. Submyotodon latirostris, M. secundus sp. n. and M. soror sp. n. are endemic species from Taiwan, whereas the other five Myotis are more widespread and also found in the mainland. An identification key is provided to ease the discrimination of these Myotinae species in Taiwan and adjacent China.
