The Scaly-footed Small-eared Shrew is known from the high Andes of Colombia. A comparison with a close relative describes it as paler, with a longer and broader muzzle.
A 2023 comparison with C. huttereri reports a larger body, paler fur, and a longer, broader muzzle.
The Scaly-footed Small-eared Shrew lives in the Colombian Andes. Like other mammals, its cells contain mitochondria that help supply energy. These structures carry genetic information that can help trace relationships with relatives.
A 2019 study used a specimen collected at El Tambo and deposited in the natural-history museum of Universidad del Cauca. Researchers extracted DNA from preserved tissue and sequenced a mitochondrial gene. Publishing the sequence together with its specimen identification made it available for later comparisons.
In the resulting comparison, this shrew and Ecuador’s Cryptotis niausa appeared on closely related branches. Some relationships differed from traditional groupings based on appearance, and the authors called for more genes and specimens. One small museum specimen opened a new route into understanding South American shrew relationships.
An extinction-risk assessment has not been added yet.
The 2019 study found inconsistencies between maps of this species’ range and publicly available collection records. With forest alteration and loss affecting the Colombian Andes, the authors emphasized checking specimen identifications and localities and updating distribution information. Linking reliable records to current habitat would provide a firmer basis for deciding where conservation is needed.
