Etymology: Dipylidium is a tapeworm name built entirely from Greek parts, and its meaning is visible in the anatomy it describes. The first element is "di-", meaning "two", and the second comes from "pylis", a gateway or gate, related to "pylē", the word for a gate. Together they mean "two-gated" or "two-doored," a description of the worm's segments, each of which carries a pair of genital openings. The name was coined by the German naturalist Karl Asmund Rudolphi in the early 1800s, when scientists were naming parasites by describing their visible features in classical terms. The term is a modern scientific coinage, so no ancient Greek writer ever used it. Its classical roots gave naturalists a neutral, Latinized vocabulary that could be read across European languages. The worm itself, a parasite of dogs, cats and occasionally humans that spreads through fleas, is the species most often called by this name.

Synonyms: tapeworm genus, cestode
