Its back is chocolate brown and its underside olive-brown. It has been recorded in wet high-elevation forests of the Tamá Massif.
The specimens are described with chocolate-brown backs and olive-brown undersides. The species has a relatively long tail and enlarged forefeet and claws.
The Tamá Small-eared Shrew inhabits humid highlands of the Tamá Massif along the Colombian–Venezuelan border. Its environments include mountain forest adjoining high-elevation grassland.
A 2017 report documented one specimen found in Tamá National Natural Park on 24 July 2014. A well-preserved dead shrew lay on a trail at 2,872 metres in the Orocué sector, within a patch of high Andean forest on the way to páramo grassland.
The researchers preserved it, checked its identity against earlier descriptions and taxonomic revisions, and deposited it in the Universidad de Pamplona museum. They emphasised renewed evidence of occurrence in the poorly documented Colombian Tamá Massif rather than an extension of the known range or elevation. One specimen documented continued presence in this mountain forest.
An extinction-risk assessment has not been added yet.
The 2017 report identifies advancing threats, including hunting and habitat loss, across the Tamá Massif and urges comprehensive conservation management and further biological surveys. Maintaining humid highland forest and documenting occurrence are relevant foundations for conserving the Tamá Small-eared Shrew.
