This Luzon mouse has a very long muzzle and small eyes. The confirmed type-specimen locality for this species is Mount Data; its muzzle and small teeth suggest it may eat soft-bodied invertebrates.
It has a long, slender muzzle, small eyes, and short, dense fur. The upperparts are dark brown, the underside gray, and the short tail and feet are brown.
Its long muzzle and small teeth may indicate specialization for soft-bodied invertebrates. This is an inference from its anatomy, not a direct feeding observation.
An extinction-risk assessment has not been added yet.
