This long-snouted rodent is known only from Mount Tapulao in Zambales Province on Luzon. The original description records it in mossy primary forest near the peak.
The golden-brown back contrasts sharply with the mainly white underside. The female specimen had pale-gray areas on the throat and parts of the belly. The upper side of the tail is dark over about its basal two-thirds and unpigmented toward the tip.
Researchers recorded it in primary mossy forest near the peak. All three captures were on the ground in earthworm-baited traps; it was not found in the surveyed lower secondary forest or disturbed montane forest.
An extinction-risk assessment has not been added yet.
