The Honduran Small-eared Shrew is a small shrew recorded in the highlands of south-central Honduras. It is separated from a similar-looking species by features of its skull and teeth.
It looks much like C. gracilis but differs in skull and dental features. It was also reported to have a longer tail than C. nigrescens merriami.
The Honduran Small-eared Shrew inhabits the highlands of central Honduras, including pine and mixed pine–oak forest. Other small-eared shrews in the region differ in their body and forelimb proportions.
A study published in 2015 compared skins, skulls and limb skeletons from western Honduran shrews and described three species previously included within another species. The already-named Honduran Small-eared Shrew was used in the comparisons.
The Celaque species was reported to have broader forefeet and longer, broader foreclaws than the Honduran Small-eared Shrew. Its upper-arm bone was also larger and more robust. The Omoa species showed the same contrasts. Comparing feet and claws, alongside overall size, revealed distinct anatomical combinations among these mountain shrews.
An extinction-risk assessment has not been added yet.
The Honduran mammal study published in August 2026 lists this species from Uyuca Biological Reserve and La Tigra National Park and identifies feral and domestic cats as a significant threat. Its pine and mixed pine–oak habitat, together with exposure to cats, are relevant considerations for local conservation.
