The Palawan Pencil-tailed Tree Mouse is a poorly documented, tree-using rodent endemic to the Palawan faunal region. Records include forest, bamboo thickets, and coconut plantations.
A diagnostic key identifies it as a large species in its genus, with ochraceous-brown dorsal fur. The underside ranges from ochraceous-white to reddish, with a yellow stripe between the upper and lower fur.
It is described as arboreal. It has been recorded in forest, coconut plantations, bamboo thickets, and buildings, but members of the genus are difficult to capture and detailed natural-history information is scarce.
An extinction-risk assessment has not been added yet.
