Broad-banded Nomad Bee Nomada signata

I attempted to catch this for closer examination but it failed to cooperate so I only have these photos to go on. Superficially similar to Flavous Nomad Bee Nomada flava, the Nomada species I seem to encounter most often, this differed in the following ways: the spots on the propodeum are yellow; the basal tergite is extensively yellow (usually red on flava); and the yellow bands on the next tergites are broad and entire, not significantly narrowing at the centre. I think that's enough to name it as signata.
