Oreohelix eurekensis uinta had not been found since its original discovery and had never been reported as a living taxon, and this had led to speculation that it is extinct. However, searches for O. e. uinta had been confounded by multiple errors in the original definition of the type locality. The type locality has now been relocated and is here redefined, and O. e. uinta is reported for the 1st time as a living taxon. Although the holotype has been lost, existing specimens believed to be paratypes have been examined, and correction of errors in the literature concerning its size and proportions is provided. O. e. uinta has been detected only in a surprisingly small area (~0.03 ha) where potential threats to its continued existence are evident.
