Cordilura fuscipes Zetterstedt, 1838 (from Sweden)
Cordilura vittipes Loew, 1872 (from Alaska)
The Palaearctic catalog (Ċ ifner, 2008) places this species in Paralleloma. Which is valid depends on zoological nomenclature rules nitpicking.
Explanation of Names
Both fuscipes and vittipes refer to dark leg markings. More often the legs are typically unmarked yellow.
Holarctic south to New Hampshire and New Mexico in mountains, possibly as far south as Maryland
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."
