Soliped, a somewhat uncommon term, refers to a mammal with a single hoof per foot. If you're searching for alternative names to soliped, there are a few others to choose from: odd-toed ungulate, which refers to animals such as horses, zebras, and tapirs; perissodactyl, which refers to even a broader range of odd-toed mammals, including rhinoceroses; and equid, a term that is more familiar as it specifically denotes members of the horse family. While these words aren't as frequently utilized as soliped, they're useful when discussing mammals with this distinctive physical feature.
