This species is recognized by the structure of the hind femur, with the basal group of peglike setae lacking lines, the distal carina being weakly developed, and the basal carina being abruptly curved dorsally. There is considerable variation among specimens under this name, and more than one species might be involved. FIGURES 99–106.
