Nomada maculata, m, left side, Charles Co. Maryland
The only bidentate Nomada I feel comfortablish identifying.
All the rest blend together morphologically and maybe molecularly. This is one of the largest and most common of the bidentates and has a unique set of tibial spurs (which is not saying much) and some general coloration patterns that are helpful. Collected in Charles County, Maryland USA. Picture by Amanda Robinson.
