Scotinomys teguina
Scotinomys xerampelinus

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

According to the review of the genus by Hooper (1972),[2] they are found in mountainous areas in Central America, at altitudes of 1000 metres to at least 3500 metres. 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 (for details see Hooper and Carleton, 1976[3]), with S. xerampelinus generally dominant over S. teguina where the species occur together (Pasch et al., 2013[4]).
