Remarks
James (1955) wrote, treating this species as Cordilura vittipes Loew:
"This is an extremely variable species; it is little wonder that it has been described under six different names. Loew described vittipes from a male and lutea from a female, both from the same locality and presumably on the same date and by the same collector. Typically, the male is predominantly black with a yellow face and yellow legs; the female typically has a yellow thorax, but the abdomen may vary from wholly yellow to wholly black. Extremes in color variation may occur within a single series, so there seems to be no way of distinguishing geographic subspecies on the basis of color variants. An occasional male may have a partly yellow thorax and an occasional female a wholly or largely black one. The femora may or may not be vittate with black."
