Question about Black and Yellow Argiope Spiders

I am new to this website and am creating a collection of insects and spiders for my local county extension agent. I collected a spider tonight that I think is a black and Yellow Argiope but the coloration is a little different than others I've seen and photographed. The primary color is more black and the spots are more white with some yellow markings just along the side. Rest of the body shape matches black and yellow argiope.

Thanks for any input. I'll try to post a photo tomorrow.

Images for Black & Yellow Argiope question

Here are my images . . . The spots seem more isolated and less yellow and the side markings are much smaller than I'm used to seeing on the Black & Yellow Argiope aurantia. The body also seems more squared off at the bottom, less rounded in shape.

But we have always had Argiope aurantia around the house - so I'm guessing this is just a variation, but I wanted confirmation.

Thanks,
Mary Ann Melton

Three Argiope common in Texas, we think:

aurantia:

argentata:

trifasciata:

Plus possibly Argiope blanda?
If you can post an image, that would be great
