The Hispid Cotton Rat, Sigmodon hispidus, is a rodent species long thought to occur in parts of South America, Central America, and southern North America. However, recent taxonomic revisions, based on mitochondrial DNA sequence data, have split this widely distributed species into three separate species. Carroll et al. (2004) indicate that the southern edge of the S. hispidus distribution is likely near the Rio Grande River where it meets the northern distribution of S. toltecus (formerly S. h. toltecus). The range of S. toltecus extends from northern Mexico south into Chiapas where it occurs in sympatry with S. hirsutus (formerly S. h. hirsutus). They have been used as laboratory animals.
