It is a medium- to large-bodied mouse-eared bat among those found in South America.
It has a forearm length ranging from {{cvt|33.1-38.3|mm|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.

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 {{cvt|760-1000|m|ft}} above sea level.
