Van Sung's Brown-toothed Shrew is known from Mt. Tay Con Linh in northeast Vietnam and Yunnan, China. On the Vietnamese mountain, it has been recorded at 1,300–2,100 m in several habitats.
The dorsal fur is slate gray with a dark-brown tinge; the ventral fur is slate gray with a pale-brown tinge. The tail tip lacks a long-hair tuft, and its dorsal surface is naked at the tip.
A 2021 survey collected it at 1,300–2,100 m on Mt. Tay Con Linh in dense bamboo, disturbed forest, and a Chinese-cardamom plantation.
An extinction-risk assessment has not been added yet.
