Bukit White-bellied Rat

The Bukit white-bellied rat is a medium-sized Niviventer with brown upperparts, sharply contrasting white underparts and a long bicoloured tail. It was formerly entangled with other white-bellied rats, so older records and measurements need specimen-based taxonomic review (Mammal Diversity Database; specialist murid revision).

It is recorded across parts of mainland and Sundaic Southeast Asia. Thai trapping studies have found it in evergreen forest, forest edge and some disturbed ground, but detailed species-specific diet and breeding data remain insufficient for a reliable summary (Thai small-mammal surveys). No national category is stated because it is absent under this name from Thailand Red Data 2025.
