Myotis Blythi

The mouse-eared bats or myotises are a diverse and widespread genus (''Myotis'') of bats within the family Vespertilionidae. The noun "''myotis''" itself is a New Latin construction, from the Greek "''muós'' (meaning "mouse") and "''oûs''" (meaning ear), literally translating to "mouse-eared".

Relationships

''Myotis'' has historically been included in the subfamily Vespertilioninae, but was classified in its own subfamily, Myotinae, by Nancy Simmons in 1998. In her 2005 classification in '' Mammal Species of the World'', Simmons listed the genera '' Cistugo'' and '' Lasionycteris'' in the Myotinae in addition to ''Myotis'' itself.Simmons, 2005, p. 499 However, molecular data indicate that ''Cistugo'' is distantly related to all other Vespertilionidae, so it was reclassified into its own family, the Cistugidae, and that ''Lasionycteris'' belongs in the Vespertilioninae.Roehrs et al., 2010 The genus ''Submyotodon'' has since been added to the subfamily, making it and ''Myotis'' its only members.

Appearance and behavior

Their ears are normally longer than they are wide, with a long and lance-shaped tragus, hence their English and zoological names. The species within this genus vary in size from very large to very small for vesper bats, with a single pair of mammary glands.

Mouse-eared bats are generally insectivores. '' M. vivesi'', and several members of the trawling bat ecomorph ''Leuconoe'', have relatively large feet with long toes, and take small fish from the water surface (they also take insects).

Longevity

''Myotis'' species are remarkably long-lived for their size; in 2018, researchers revealed that a longitudinal study appears to indicate that ''Myotis'' telomeres do not shrink with age, and that telomerase does not appear to be present in the ''Myotis'' metabolism. 13 species of ''Myotis'' bats live longer than 20 years and 4 species live longer than 30 years.Growing old, yet staying young: The role of telomeres in bats’ exceptional longevity
These Bats Don't Seem to Die of Old Age—Can They Help Extend the Human Lifespan?
by Kate Lunau, at '' Vice''; published February 7, 2018; retrieved June 12, 2018 The longest-living species of ''Myotis'', and longest-living bat in general, is thought to be the Siberian bat (''M. sibiricus''); one individual discovered in 2005 was found to be over 41 years old at the time.

Species

Traditionally, ''Myotis'' was divided into three large subgenera—''Leuconoe'', ''Myotis'', and ''Selysius''. However, molecular data indicate that these subgenera are not natural groups, but instead unnatural assemblages of convergently similar species.Simmons, 2005, p. 500 Instead, ''Myotis'' species largely fall in two main clades, one containing Old World and the other New World species. The ITIS presently divides it into three subgenera: ''Chrysopteron'' (containing most reddish-colored Old World species), ''Myotis'' (containing almost all other Old World species), and ''Pizonyx'' (containing all New World species and the Eurasian '' Myotis brandtii'' and '' Myotis sibiricus'', which are more closely related to New World species than to other Old World species). The Asian species ''Myotis latirostris'' falls outside the clade formed by these main groups, and has since been reclassified into a separate genus, ''Submyotodon'', alongside several others.

''Myotis'' is a highly species-rich genus, and the classification of many species remains unsettled. The taxonomy below is based on that of the ITIS in 2021. Some differences in taxonomy from the 2005 third edition of '' Mammal Species of the World''Simmons, 2005, pp. 500–518 are indicated in footnotes.
