The Oaxacan broad-clawed shrew is a small shrew recorded in the mountains of Oaxaca, southern Mexico.
The back is dark brown and the underside lighter brown; its feet and claws are broad.
Five shrews were collected in pine and pine–oak forest at 2,330–2,730 metres during the 2010–2011 western Oaxaca survey, adding forest records for an animal known from a wet highland meadow.
Researchers installed one-litre pitfall containers near suitable sites including decaying logs. Five of twelve shrews captured were this species; specimens were preserved and identified using morphological keys.
A 2000 museum revision restricted its name to Cuatro Venados and adjoining Yucuyacua, separating the similar shrews of the southern Miahuatlán range as C. phillipsii.
An extinction-risk assessment has not been added yet.
The 2012 researchers highlighted community-led forest restoration, sound forest management and hunting restrictions in west-central Oaxaca, noting their importance for regional mammals including this narrowly distributed shrew.
