Geophilus is a genus of centipedes that contains more than 200 species, all of which are carnivorous predators. Although there are many species, there are not many synonyms for the word Geophilus, as it is relatively specific to this genus of centipedes. Some possible synonyms for Geophilus might include soil centipedes, earth centipedes, or ground centipedes. These terms are more general, but still refer to the same general group of centipedes that belong to the Geophilus genus. Other possible synonyms could include lithobiids, which are another type of centipede that is found in soil habitats.
