Argasidae

Pronunciation: ar-gas′i-dē

Definition: Family of ticks (superfamily Ixodoidea, order Acarina), the soft ticks, so-called because of their wrinkled, leathery, tuberculated appearance that fills out when the tick is engorged with blood. Argasidae contains four genera: Argas, Ornithodoros, Otobius, and Antricola; argasid ticks, chiefly species of Ornithodoros, harbor and transmit spirochetes of the genus Borrelia that cause relapsing fever in birds and mammals.
