Myotis izecksohni

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 (1.30–1.51 in). 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.^[3]

M. izecksohni was first documented in southeastern Brazil and has since been discovered in far northeastern Argentina.^[2] It has been found at a range of elevations from 760–1,000 m (2,490–3,280 ft) above sea level.^[1]
