C. levicula is among the smallest shrews on Sulawesi with average body size of approximately 4.4 grams (Esselstyn et al. 2021). It is found from lower to mid-montane tropical to upper montane rainforests at altitudes up to 2,000 m asl (Esselstyn et al. 2021). There is no information available on whether or not it can adapt to anthropogenic habitats outside of forest.

The species has been found in the northern part of the west-central area of endemism (Mts. Rorekatimbo and Torompupu, Central Sulawesi Province), in two lowland areas near the boundary between the west-central and south-east areas of endemism (Wasponda and Tolala, Central Sulawesi Province), and in the east-central area of endemism (Mts. Katopasa and Tompotika, Central Sulawesi Province (Esselstyn et al. 2021). It is found across a broad elevational range, from approximately 400 m up to 2,000 m asl (Esselstyn et al. 2021).

It occurs in some protected areas such as Lore Lindu National Park, Central Sulawesi. Further studies are needed on the distribution, abundance, natural history and threats to this species.
