The straight-billed reedhaunter has a relatively small range, extending from the states of Santa Catarina and Rio Grande do Sul in extreme southern Brazil, through to southern Uruguay and eastern Argentina in the provinces of Entre Ríos and extreme north-east Buenos Aires. Within this range, the straight-billed reedhaunter is very sparsely distributed, but is locally common in appropriate habitats (2).

The straight-billed reedhaunter is most commonly found in marshland, but also occupies stands of short trees and shrubs bordering wet areas up to elevations of 1,100 metres. This species has a close association with the spiny herb commonly called caraguata (Eryngium species), which grows around marshes and in upland thickets (2).
