This skunk occurs in forests of the northern Yucatán Peninsula. Camera traps in a small urban vegetation fragment in Mérida recorded it at night.
An adult female collected at Chichén Itzá on 2 March 1936 measured 270 mm in total length, including a 104 mm tail. It was described as smaller than S. angustifrons, with smaller teeth and a narrower tooth row, and with black feet rather than the white feet of S. pygmaea.
The study site in northeastern Mérida was a roughly 38-ha vegetation fragment. It was originally tropical dry forest and had become secondary vegetation after agriculture and urban growth. Camera traps recorded the skunk at night.
An extinction-risk assessment has not been added yet.
