Myotis izecksohni

Myotis izecksohni is a species of mouse-eared bat that is endemic to Brazil and Argentina.

Taxonomy
M. izecksohni was described as a new species in 2011. The holotype had been collected in 2005 in Tinguá Biological Reserve. The eponym for the species name "izecksohni" is Brazilian biologist Eugênio Izecksohn.

Description
It is a medium- to large-bodied mouse-eared bat among those found in South America. It has a forearm length ranging from 33.1-38.3 mm. Its fur is long with a silky texture; the fur of its back is bicolored, with the basal two-thirds of individual hairs dark, while the distal third is dark-brown to medium-brown. The fur of its belly is also bicolored, though overall lighter brown than the back fur. It lacks hairs along the outer edge of the uropatagium, which is a useful field identification characteristic.

Range and habitat
M. izecksohni was first documented in southeastern Brazil and has since been discovered in far northeastern Argentina. It has been found at a range of elevations from 760-1000 m above sea level.
