Diagnosis. Males and females of N. tiftonensis are most similar to N. texana . See Diagnosis under that species for identifying characters.

Distribution. Nomada tiftonensis is known from Georgia north to Maine and west to Ontario and Wisconsin.

Material examined. 29 specimens were examined from ME, GA, NJ, NH, IN, MD, ON, SC, MI, NY, and WI.

Molecular results. We obtained DNA barcoding data from seven specimens of N. tiftonensis (five females and two males) sampled from widely separated localities (Ontario, Maryland, and South Carolina) ( Table 1). The sequence divergence among these specimens ranged from 0–0.2%

Variation. In N. tiftonensis , most male specimens have a completely black supraclypeal area, while others have vague yellowish patches present, and a few have solid yellow blocks (Fig. 42). In male N. tiftonensis the labrum varies from completely yellow to nearly all dark; the labrum in all observed N. texana males was completely yellow.
