Crunomys is a genus of rodent in the family Muridae widespread to the Southeast Asian. They are mid-sized rodents, similar to rats, that live on the ground of tropical rainforests. There they build nests, padded with fallen leaves from trees. They feed on roots, fallen fruit, and other plants, as well as insects. All species are shy and avoid food from humans.
Taxonomy
This genus previously contained only four species, namely C. celebensis, C. fallax, C. melanius,C. suncoides, and C tompotika. Then in 2025 through mitochondrial and nuclear differentiation, the genus Maxomys which was considered a separate species was synonymized to the genus Crunomys and now 24 species have been identified.[1]
