Oligia rampartensis. Revised status from Schmidt and Anweiler (2010a). This species differs from O. violacea in having a reddish rather than white hindwing, a unicolorous thorax (reddish center in O. violacea), and numerous differences in the genitalia and DNA. They occur sympatrically in many areas of western North America, although O. violacea predominates on the West Coast states and O. rampartensis is mainly in the interior.
