This small shrew was described from Ke Go Nature Reserve in Vietnam. The paper reports only one holotype, so its range and way of life remain poorly known.
It is very small, with short brownish-grey fur, a short tail and feet, and conspicuous blackish whisker patches above the upper lip.
Crocidura kegoensis has a short snout and a broad, flattened braincase. A deep indentation behind the last upper premolar leaves a crescent-shaped gap before the next tooth. Its small skull has a distinctive outline and tooth arrangement.
In 2004, researchers measured skulls and teeth and compared the shrew with Crocidura wuchihensis. The focal specimen had a shorter skull and braincase than the comparison sample, while measurements of skull breadth fell within that sample’s ranges.
Together, these measurements describe a skull that is broad relative to its length. Comparing length and breadth separately reveals proportions that differ from a uniformly reduced version of a similar shrew. An analysis combining several measurements also separated the name-bearing specimen from the comparison specimens.
An extinction-risk assessment has not been added yet.
Retaining the lowland forest where the shrew was first found and continuing small-mammal surveys would support its conservation. The 2004 original study emphasized further surveys in remaining lowland and mountain forests. The name-bearing specimen came from primary forest inside Ke Go Nature Reserve. Habitat protection and further distribution surveys are complementary priorities.
