Ammopelmatus monahansensis
(Stidham & Stidham, 2001)
Ammopelmatus monahansensis is a of in the Stenopelmatidae, described by Stidham & Stidham in 2001. The Ammopelmatus comprises sand dune species found in the southwestern United States. These flightless orthopterans are characterized by their large size, habits, and activity patterns. A. monahansensis is one of several described species within this genus that are restricted to specific sand dune systems.

Identification
Ammopelmatus monahansensis can be distinguished from other Ammopelmatus by geographic distribution and presumably by subtle morphological differences in body proportions, coloration, and genitalic structures, though specific diagnostic characters require examination of type material. The is characterized by large, robust bodies with abbreviated wings, enlarged hind adapted for digging, and a distinctive rounded . Species-level identification typically requires comparison with described and knowledge of collection locality.
Habitat
Sand dune systems; specifically associated with the Monahans Sandhills region of Texas. The inhabits loose, sandy substrates where it constructs burrows. Vegetation in these typically consists of scattered grasses, shrubs, and other plants adapted to arid, sandy conditions.
Distribution
to the Monahans Sandhills in western Texas, USA. The is restricted to this specific sand dune system, reflecting the pattern of localized characteristic of the Ammopelmatus.
Behavior
and . Like other Ammopelmatus , individuals likely spend daylight hours in burrows and emerge at night to forage. The enlarged hind legs are adapted for digging in sandy substrates. Jerusalem crickets are known to produce sound by drumming their against the substrate, though specific behavioral details for A. monahansensis are not documented.
Ecological Role
As a large, predatory/ in sand dune , likely functions as a of smaller invertebrates and scavenger of organic matter. The burrowing activity may contribute to soil aeration and nutrient mixing in sandy substrates.

Taxonomic Note
The Ammopelmatus was established to accommodate sand dune Jerusalem crickets previously confused with Stenopelmatus. The specific epithet 'monahansensis' refers to the Monahans Sandhills, the type locality in Texas.
Conservation Status
As a narrow restricted to a specific sand dune system, the may be vulnerable to loss from sand mining, oil and gas development, and vegetation encroachment due to altered disturbance regimes. However, no formal conservation assessment has been published.
