Description of region, plus list of endemic species per Paulsen & Smith (2005)

The Monahans Sandhills is a belt of active and vegetated dunes approximately 110 km long and 32 km wide on the Pecos Plain running from extreme southeastern New Mexico to Crane County, Texas, in the south. The sandhills are a recent geologic feature formed within the last 12,000 years as the region became more arid (currently ~30 cm/yr precipitation) and windblown sands accumulated (Machenberg 1984). Monahans Sandhills State Park is situated near the middle of the dunes system in Winkler and Ward counties, Texas. Though the sandhills are relatively young, they are home to a variety of endemic psammophilous (sand-loving) plants and animals.

Beetles endemic to the Monahans Sandhills region include:
