Definition
"Genus Micromyx" is a deprecated term used in the past for classifying certain small rodents, particularly harvest mice, within the Muridae family. This classification is no longer accepted in modern taxonomy, as the species previously assigned to *Micromyx* have been reclassified into other genera. Think of it as an outdated map; it once showed the way, but now there are more accurate and detailed maps available. Modern molecular and morphological studies have led to a more refined understanding of rodent phylogeny, resulting in these taxonomic revisions. The name *Micromyx* is still encountered in older scientific literature.
