The paired palps are located on either side of the hypostome and the medially-located chelicerae. Each palp consists of four distinct segment (= articles). In ixodid ticks (Family Ixodidae), the fourth palpal segment is reduced and located in a cavity in the terminal end of segment three. In argasid ticks (Family Argasidae), all four palpal segments are similar in length. The palps provide sensory information about the condition of the host skin in preparation for selecting a site for feeding.
