The genus Centris contains circa 250 species of large apid bees occurring in the Neotropical and Nearctic regions, from Kansas to Argentina. Most females of these bees possess adaptations for carrying floral oils rather than (or in addition to) pollen or nectar. They visit mainly plants of the family Malpighiaceae to collect oil, but also Plantaginaceae, Calceolariaceae, Krameriaceae and others. Recent studies have shown they are sister to the corbiculate bees, the most well-known and economically important group of bees 
At earlier technology nodes, when features were larger, a greater range in variation in etch depth, line or space width, or profile angle could be accommodated without affecting device performance. Similarly, occasional particles remaining on feature surfaces did not jeopardize device reliability. At the 1x/10nm node, however, the slightest differences in etch depth, line or space width, or profile angle can be fatal flaws in chip manufacture. And defect-free surfaces are equally essential.
