Scotinomys teguina
Scotinomys xerampelinus

Scotinomys is a genus of rodent, the singing mice, in the family Cricetidae.[1] Together with Baiomys, it forms the tribe Baiomyini. It contains the following species:

They are found in mountainous areas in Central America, at altitudes of 1000 m to at least 3500 m.[2] As their common name indicates, they are notable for their acoustic communication. They are insectivorous. The two species show substantial divergence in behaviour and reproduction,[3] with S. xerampelinus generally dominant over S. teguina where the species occur together.[4]
