A new species of Nebria Latreille (Coleoptera: Carabidae: Nebriini) from the Grand Canyon, Arizona

Nebriageorgei, new species (Colcoptera: Carabidae: Nebrinii), is described from the riparian zone along the Colorado River in the Grand Canyon, Arizona (type locality - Arizona, Coconino County, Grand Canyon National Park, Colorado River). The first new Alebria described from North America in more than two decades, this species is most closely related to Alebria desolata Kavanaugh and Alebria navajo Kavanaugh, based on characters of external and male and female genitalic form and structure, and on preliminary DNA-sequence comparisons. This species is named in honor of George l. Eugene Ball, who first recognized specimens of this taxon, sent to him for identification, as likely representing an Undescribed species.
