adult Haller's organ posterior capsule
A cavity on the dorsal surface of the tarsus of leg I that contains a number of single-walled multiporose olfactosensilla and other apparently non-sensory setae. The sensilla are innervated by as many as 29 sensory neurons. In most ixodid ticks, the roof ofthe capsule has a thin, narrow slit. In a species of the genus Ixodes, the opening is large and circular. In some argasid ticks, the roof of the capsule is perforated with a reticulated lattice instead of a simple roof.
