Where are spiny mice of the subgenus Pyromys found?

Spiny mice of the subgenus Pyromys are found in Sri Lanka, India, and mainland Southeast Asia.1

It is important to clarify that while the term "spiny mouse" is often associated with the genus Acomys (the African spiny mouse), the subgenus Pyromys specifically refers to a group within the genus Mus. These Pyromys species are characterized by flat, channeled spines on their upperparts and undersides, which distinguish them from other mice groups. Their natural range consists primarily of open grasslands or grassy patches within forests.21
