S. nigripes vs. H. analis

I have verified differences given below on BG images of mating couples; not any of the individual BugGuide observations of either species is correctly identified.
If it is not clearly seen if profemora are toothed, or not, or colour pattern of underside is not verified, discrimination works as follows:

Front tibiae straight = H. analis female;

Front tibiae curved: H. analis male, or S. nigripes (both sexes);

If head behind eyes long, and parallel-sided = H. analis male;

(parallel-sided also in female, but shorter - compare previous link)

The neck behind eyes is widened behind in both sexes of S. nigripes, but this may not be of easy observation in photographs:
