We study weak isosinglet vectorlike leptons that decay through a small mixing with the tau lepton, for which the discovery and exclusion reaches of the Large Hadron Collider and future proposed hadron colliders are limited. We show how an e+e− collider may act as a discovery machine for these τ′ particles, demonstrate that the τ′ mass peak can be reconstructed in a variety of distinct signal regions, and explain how the τ′ branching ratios may be measured.
