The word cercoid is derived from the suffix -oid, which means resembling or having the shape of. In this case, cercoid specifically refers to something that resembles or has the shape of a cercus. A cercus (plural: cerci) is a specialized appendage found on the rear of certain arthropods, such as insects and crustaceans. The term cercus itself comes from the Greek word kerkos, meaning tail or appendage. So, cercoid essentially means resembling a cercus.
