The Ixodidae are a family of ticks containing the hard ticks.


They are distinguished from the other main family of ticks, the soft ticks (Argasidae) by the presence of a scutum or hard shield.[1] In both the nymph and the adult, a prominent capitulum (head) projects forwards from the animal's body; in the Argasidae, conversely, the capitulum is concealed beneath the body.

The family contains these genera:[2]
