Idia occidentalis (Smith, 1884) , REVISED STATUS

Fig. 22

Based on differences in the genital morphology between Idia lubricalis (Smith, 1895) , from the eastern U.S., and Idia lubricalis occidentalis , from southern California, I elevate the latter to species status as originally proposed by Smith. Superficially, I. occidentalis is larger and considerably paler than I. lubricalis . The male valve of occidentalis ( Fig. 22 ) is straighter than that of lubricalis ( Fig. 23 ) at the point where the valve makes a more pronounced outwards angle. Consistent with its Latin name, I. occidentalis occurs from California as far north as Wyoming, and east to New Mexico and Arizona. The type locality is Havilah, Kern County, California. Idia lubricalis occurs in the eastern U.S. and reaches the Pacific Northwest, where it is sympatric with I. occidentalis .
