Murinum

Murinum is a Latin adjective meaning mouse-like or of a mouse. In biological nomenclature, murinum functions as a species epithet that can be attached to different genera to form a binomial name. It does not designate a single taxon; rather, it appears across various groups to convey a perceived resemblance to mice or a small size.

The root in murinum comes from Latin muris, meaning mouse, with the suffix -inus forming an adjective meaning belonging to or resembling. In botanical and zoological naming, the ending of an epithet agrees with the gender of the genus: murinus, murina, or murinum may appear depending on the genus’s grammatical gender. The same linguistic heritage underlies the English term murine, which describes things related to mice or rodents in general.

Usage and interpretation can vary by taxon and namer’s intent. Because epithets are reusable across many groups, the presence of murinum in one species name does not imply close evolutionary relationship to another species bearing the same epithet. Instead, it reflects a descriptive remark by the classifier at the time of naming.
