The Striated Grasswren lives in open mallee woodland in South Australia. This entry follows the sandplain subspecies described in the state fact sheet.
It is brown with black and white streaking above and a black stripe on each side of the throat. Females have a chestnut patch below the wing.
It uses open mallee with sparse shrubs and a spinifex-dominated ground layer. It hops on the ground for insects; spinifex also provides seeds, spiders, nesting material, and shelter.
An extinction-risk assessment has not been added yet.
