It occurs in the Great Plains and adjacent regions of North America, with records from Nebraska, South Dakota, Texas, and Mexico. The inhabits open, sparsely vegetated areas.

Identification
As a Trimerotropis , T. pistrinaria likely shares the -typical traits of banded wings and cryptic body coloration. The specific epithet "pistrinaria" (Latin for "of a mill" or "bakery") may allude to pale or dusty coloration. Definitive field identification requires examination of wing banding patterns, hind tibia coloration, and male genitalia. It can be distinguished from the similar T. latifasciata (broad-banded ) by distribution and preferences, as T. latifasciata occurs on lichen-encrusted clay exposures while T. pistrinaria occupies more barren, open terrain.

Habitat
Barren, open terrain with sparse vegetation. The and specific epithet suggest association with disturbed or minimally vegetated ground, possibly including prairie barrens, sandy areas, or overgrazed rangeland.
Distribution
North America: Nebraska, South Dakota, Texas; Mexico (northeastern region). Central America records require verification.
Similar Taxa

- Trimerotropis saxatilisLichen grasshopper is more greenish with speckled pattern, associated with lichen-covered rocks rather than barren terrain.
