Wow Janet that was a big job to go through such big part of the huge Fabaceae list!
I went through the rest, roughly basing myself on available images or herbarium ex. for the genus, and Luetzelburgia is the most likely candidate, as it is not Luetzelburgia guaissara it must be Luetzelburgia trialata, the only other one in that region.
The open flowers on Luetzelburgia guiaisara look very crumpled, it is hard to know how the flowers on mine would turn out when maturing as they are mostly still in bud..
Its synonym Vatairea trialata is interesting as the flowers of that genus look like a match for mine,

The seedpods are a perfect match for the genus!
