Unfortunately, there are no synonyms for the word "duplicidentata" in the English language. This term specifically refers to a type of rodent that has two pairs of front teeth. The scientific name for this group of rodents is Aplodontidae, and it includes only one living species, the mountain beaver. While there may be other animals that have two pairs of front teeth, they would not be classified as duplicidentata unless they belong to the Aplodontidae family. It is important to note that using proper scientific names and terminology helps to avoid confusion and ensures accuracy in communication within the scientific community.
