This small shrew is recorded from montane forest in northwestern Sulawesi. The original description reports specimens from mountains at about 1,400–1,600 m.
Its coat is nearly uniform brown, including the feet, ears, and tail. The tail is shorter than head-and-body length and has bristles along about three-quarters of its length.
On Mount Dako, this shrew and Crocidura lea both occur around 1,600 metres. Both belong to the island’s small-bodied shrews; C. lea also occurs lower down the mountain.
Mount Buliohuto showed a different pattern. Researchers compared morphology and genetic evidence to distinguish species. In the samples reported in 2021, this species occurred at 1,375–1,390 metres and C. lea at 400–1,210 metres, without overlap in their recorded elevations. The authors proposed investigating how body size, feeding ecology and leaf-litter environments relate to coexistence.
An extinction-risk assessment has not been added yet.
The 2021 description documented this shrew in montane forests on Dako and Buliohuto. The authors recommended surveys in mountains west and south of Dako and east of Buliohuto. Retaining known forest habitat and clarifying its occurrence on surrounding mountains would provide a foundation for conservation.
