Anatomy and physiology

The mouse is the smallest species in its genus, measuring in total "230-255 mm; tail: 107-116 mm; hind foot: 31-35 mm; ear: 21 - 22 mm" and weighing 60-84 grams. [3] On its dorsal side, the mouse has long, dense, soft, dark brown fur, with dark gray ventral fur turning a lighter gray-brown at the tips. Its tail is bicolored, "dark grayish-brown dorsally and nearly white ventrally." [3]

Ecology

The Mount Tapulaou forest mouse lives in old growth cloud forests and regenerating secondary forests at a height of 2024 m, with a lower limit somewhere between 1690 m and 2024 m. It is unknown how extensive chromium mining of the habitat affects the species. [3]

Behavior

The mouse eats seeds and invertebrates such as earthworms. It is nocturnal. [3]
