This shrew is recorded in southern Vietnam and northeastern Cambodia. The original description reports dark gray dorsal fur that becomes paler underneath and specimens from several forest settings.
In described specimens, dorsal fur is dark gray and grades to a paler underside. The tail is moderately long with bristles near its base, and the dorsal feet are paler than the body.
The rearmost lower molar has a simple back portion, retaining one cusp. It lacks the basin bounded by several structures found in the similarly sized Crocidura indochinensis.
The 2010 description illustrated a Cambodian specimen beside a Vietnamese C. indochinensis. Tooth shape, together with tail and skull proportions, distinguished the two. The description used thirteen specimens from four localities, including Ma Da material collected in 1994, Virachey specimens from 2006 and Vietnamese survey specimens from 2007.
An extinction-risk assessment has not been added yet.
The 2024 Fauna & Flora report describes forest degradation from historical logging in Virachey National Park, a confirmed locality for this shrew. It also reports that an adjoining biodiversity conservation corridor was incorporated into the park in 2023, expanding the protected area.
