Two males and a female of Zaitzevia posthonia Brown 2001 were collected from a shallow riffle in a swift, second-order stream west of the continental divide near Lincoln, Montana. This new record confirms the presence of the species in the state, and extends the range of the species 267 km northeast of the nearest previously known record.
