This highland shrew has specimen records from Costa Rica and Panama. It has a relatively long tail; locomotor analyses suggest it is unlikely to be truly semi-aquatic, although the classifications remain uncertain.
Its tail is relatively long compared with many other species in the genus. It lacks the short hair fringes along the digits and tail that are typical of semi-aquatic shrews.
The Talamancan Broad-clawed Shrew inhabits the mountains of Costa Rica and Panama. Its genus extends from North America to northern South America, with many species occupying separate mountain regions.
A 2021 study sequenced mitochondrial DNA from thirteen tissue samples representing eleven species, then combined additional published gene sequences in a broader analysis. The analyses supported a close relationship with Central American relatives and also tested alternative relationships with a group found mainly in South America.
The authors proposed alternative explanations: ancestors may have moved from Central to South America more than once, or the ancestor of this species may have moved back north from South America. Studying one small mountain mammal thus opened questions about the historical movements connecting its distant relatives.
An extinction-risk assessment has not been added yet.
The 2021 study warns that high-elevation habitats and restricted distributions can make small-eared shrews vulnerable to warming and habitat destruction, and calls for greater conservation attention to these mountain mammals. For the Talamancan Broad-clawed Shrew, the mountain environments of Costa Rica and Panama are therefore central conservation considerations.
