Hylaeamys acritus
The name is derived from the Greek word ακριτος 'confused, doubtful', because it could easily be confused with species such as H. megacephalus and Euryoryzomys nitidus.It is known only from northeastern Bolivia; its type locality is within Noel Kempff Mercado National Park.[1] The rodent is terrestrial and is found in moist lowland semideciduous forest and savanna.[1] It has olive brown coloration on its back; the cheeks and flanks are amber, and the top of the head is dark.Chest fur between the front legs is thick and 3 to 4 mm long.
