Synonyms. Synaptomys kansasensis

Mictomys is reported from six sites within SAM Cave; specimens identifiable to species (M. kansasensis) occur in four of these (Rogers et al. 2000). Although Rogers et al. treat this as a genus, Musser and Carleton (2005) consider it to be a subgenus of Synaptomys, currently represented by the Northern Bog Lemming (Synaptomys borealis).
