Aphaenogaster uinta Wheeler 1917

A (North American) Great Basin and Colorado Plateau ant that favors arid areas. It can be found in cool desert, pinyon-juiper and coniferious forest habitats. Aphaenogaster uinta nest under wood or stones but will also build in exposed situations, creating nest openings with 6 to 8 cm craters. They forage nocturnally and nests can contain several hundred workers.

A small to medium-sized bicolored species with a yellowish-red head and mesonotum that is partially shiny. The gaster is strongly shining and is much darker than the rest of the body.

Neartic; Nevada, northern California, southwestern Colorado, southern Idaho, Utah and northeastern Arizona.
