Description
Little has changed since Creighton’s study. Examination of recent collections suggests that while western populations do average slightly smaller than eastern populations, there is considerable overlap, making reliable separation impossible. Color shows a similar pattern with geographic differentiation but considerable overlap. It seems apparent that these two forms are variants of a single variable species. We therefore consider A. subterranea valida Wheeler to be a junior synonym of A. occidentalis (Emery).
Distribution
This species is found from British Columbia south to California and east to Montana and Colorado.
