Xenochodaeus simplex

Members of Xenochodaeus can be distinguished from related genera by genitalic characters, particularly the structure of the male aedeagus. X. simplex specifically may be separated from congeners by subtle differences in body proportions and elytral punctation, though precise identification often requires examination of genitalia.

Sandy habitats including sand dunes, riverine sands, and other loose sandy substrates in arid and semi-arid landscapes. The species is specifically associated with psammophilic (sand-loving) environments.

Western North America: United States (Arizona, Colorado, Montana, Nevada, New Mexico, Oregon, Texas, Utah), Canada (Alberta, Manitoba, Saskatchewan), and northern Mexico (Chihuahua).

Adults have been observed active on sand surfaces, particularly during evening hours. Like other Ochodaeidae, they are likely nocturnal or crepuscular, burrowing into sand during daytime.

As a psammophilic beetle, likely contributes to nutrient cycling in sandy ecosystems through feeding and burrowing activities. Specific ecological functions remain poorly documented.
